Transmission Repair Cost UK: Price Guide and Warning Signs Every Driver Should Know

There is a very particular kind of dread that arrives when your car does something it has never done before. A clunk travelling up through the gear lever. A hesitation when you pull away from a roundabout. A faint burning smell that was not there last week. For most drivers, that moment is followed immediately by one question: how much is this going to cost me?

The transmission, or gearbox as it is more commonly called in the UK, is one of the most complex and expensive systems in any vehicle. Whether you drive a manual hatchback through Farnborough every morning or an automatic SUV on longer runs into Surrey, a failing transmission affects every journey you take. Catching it early, understanding what it means, and knowing your options can be the difference between a manageable repair and a bill that calls the whole car into question.

This guide gives you a clear, honest breakdown of what transmission repair costs in the UK, what the warning signs look like before they become emergencies, and how to make a confident, informed decision when you are sitting across from a mechanic with a quote in hand.

What Does a Car Transmission Actually Do?

The transmission is the mechanical bridge between your engine and your wheels. Every time the engine produces power, the transmission decides how much of it reaches the road and at what speed ratio. Without it, the engine would either stall at low speeds or overspeed at high ones. It manages torque, controls gear ratios, and keeps your car moving smoothly whether you are crawling through Aldershot town centre or joining the A31 dual carriageway.

In a manual gearbox, the driver makes those decisions using the clutch pedal and gear lever. In an automatic, the system handles them through hydraulic pressure, planetary gear sets, solenoids, and an electronic Transmission Control Module, or TCM. Modern dual-clutch and CVT transmissions are even more electronically complex. That complexity is precisely why transmission problems are expensive to fix, and why catching them early almost always saves money.

Stat: 78% of new cars sold in the UK now feature automatic transmission, meaning the majority of drivers on UK roads face higher repair complexity and higher potential costs when their gearbox develops a fault.

Stat: Most modern gearboxes are designed to last between 150,000 and 200,000 miles when properly maintained, yet low or contaminated fluid remains the single most common cause of avoidable gearbox failure across all transmission types.

6 Warning Signs Your Transmission Needs Attention

The earlier a transmission problem is caught, the cheaper it is to fix. A minor fluid service or solenoid replacement can become a full rebuild if the warning signs are ignored for long enough. Here is what to look out for, and what each sign means mechanically.

Warning Sign	Urgency	Likely Cause	Typical Next Step
Slipping gears	Book soon	Low fluid, worn clutch plates	Fluid check and diagnostic
Delayed engagement	Book soon	Low ATF, valve body fault	Fluid top-up and inspection
Grinding or whining noise	Book now	Worn synchros or bearings	Specialist inspection
Burning smell	Book now	Overheating, burnt fluid	Stop driving if severe
Fluid leak under car	Book now	Worn seal or gasket crack	Seal repair and fluid refill
Dashboard warning light	Stop and check	TCM fault, limp mode	Diagnostic scan required

1. Slipping or Jumping Gears

If your engine revs climb but your car fails to accelerate in proportion, the transmission is slipping. It feels as though the car has momentarily forgotten what gear it is in. In a manual, this is often linked to a worn clutch or low gearbox oil. In an automatic, worn clutch plates or low ATF are the most common culprits. Left unaddressed, slipping gears can progress from an irritating hesitation into a complete loss of drive.

Drivers around Tongham and Ash Vale who do a lot of stop-start commuting often report noticing this symptom first at slow speeds before it starts appearing at higher speeds too. That progression is a sign the damage is spreading, and the repair window is narrowing.

2. Delayed Engagement When Pulling Away

You shift into drive or first gear and there is a pause before the car moves, as though the gearbox needs a moment to decide. This delayed engagement is one of the clearest early warnings of an ATF problem or a valve body fault. Valve bodies are the hydraulic control systems inside automatic gearboxes that direct fluid to the right clutch packs at the right time. When they fail, gear engagement becomes sluggish and unpredictable.

This is the kind of symptom that is easy to dismiss because the car still moves eventually. Do not dismiss it. The longer the valve body is left under strain, the more likely it becomes that the damage spreads to surrounding components, turning a targeted repair into a much larger rebuild.

3. Grinding, Whining, or Clunking Noises

Unusual sounds from a transmission carry specific meanings. A whining noise that increases with speed usually points to worn bearings. Grinding during gear changes in a manual suggests damaged synchromesh rings, the components that allow smooth shifts between gear ratios. A clunking sound when changing gear or pulling away can indicate worn transmission mounts or excessive play in internal components.

No new noise from a gearbox is harmless. Even if the noise appears only occasionally at first, it will become consistent as the underlying wear progresses. Getting a specialist to listen during a test drive is far cheaper than waiting for the noise to become constant. It is also worth noting that a grinding noise when braking can sometimes be mistaken for a drivetrain or gearbox fault, so separating the two through a proper inspection saves both diagnostic time and unnecessary expense.

4. A Burning Smell From the Bonnet or Cabin

Transmission fluid has a distinctive sweet smell when fresh. When it overheats, degrades, or leaks onto hot exhaust components, that sweetness turns into something unmistakably burnt, like scorched rubber or hot metal. That smell means the fluid is no longer protecting the internal components it was designed to protect. Friction builds, temperatures rise further, and the damage accelerates rapidly.

A burning smell combined with any other warning sign on this list is a reason to stop driving and call a garage. Continuing to drive in that condition can take a repairable transmission and turn it into one that needs a full replacement.

5. Red or Brown Fluid Leaking Under the Car

Healthy automatic transmission fluid is bright red and semi-transparent. If you notice a red or reddish-brown puddle beneath your car after it has been parked overnight, that is ATF leaking from a worn seal, a cracked transmission casing, or a failing drain plug. Manual gearbox oil is darker and amber in colour. Either way, fluid under the car is never something to park and ignore.

Fluid leaks are among the most straightforward transmission repairs when caught early. A seal replacement is a fraction of the cost of the damage caused by a gearbox running without sufficient fluid. Drivers in Fleet and Farnham who notice a small wet patch on their driveway in the morning should treat it as an urgent prompt, not a minor inconvenience.

6. Dashboard Warning Lights

Modern vehicles are equipped with OBD-II diagnostic systems that continuously monitor transmission behaviour. When the system detects a fault, it may trigger the check engine light, a dedicated transmission symbol, or cause the vehicle to enter limp mode, a protective state that locks the gearbox into a single low gear to prevent further internal damage.

A warning light alone does not confirm a gearbox fault, it also flags issues with the TCM, solenoids, or sensors. But a warning light alongside any other symptom on this list is a strong signal that a diagnostic scan is needed without delay. Many garages in and around North Camp and Ash offer diagnostic checks for well under £100, which is a small price for the clarity it provides.

How Much Does Transmission Repair Cost in the UK?

There is no single figure that covers transmission repair costs because the price depends on what type of gearbox your car has, what has gone wrong inside it, how long the repair takes, and the labour rates at your chosen garage. What the ranges below can do is help you understand whether a quote you receive sits in a reasonable bracket and whether a repair, rebuild, or full replacement is the more sensible route for your situation.

To keep your vehicle running reliably alongside any transmission work, a thorough car service is always worth considering at the same time, particularly if the transmission fault has been developing gradually over several thousand miles and other systems may have been affected.

Stat: Labour typically accounts for approximately 50% of the total transmission repair bill in the UK. Garage labour rates in the South East, including Hampshire and Surrey, range from £60 to £80 per hour on average, compared to £40 to £60 per hour in northern regions.

Stat: UK garage labour rates have risen by approximately 15% year-on-year in recent years, making early intervention and preventive maintenance more financially important than ever for UK drivers.

Manual Gearbox Repair and Replacement

Repair Type	Complexity	Typical Cost Band
Fluid leak or seal repair	Low	Entry level
Solenoid replacement	Low to medium	Low range
Bearing replacement	Medium	Low to mid range
Clutch plate replacement	Medium	Mid range
Full gearbox rebuild	High	Upper range
Full replacement, reconditioned unit	High	Mid to upper range
Transmission fluid change	Very low	Entry level
Diagnostic scan	Very low	Entry level

Manual gearboxes are generally the more straightforward and less expensive option to repair. Their internal architecture is simpler: gears, shafts, synchromesh rings, bearings, and a clutch system rather than the hydraulic and electronic complexity of an automatic. Common failures include worn synchromesh, damaged bearings, and clutch-related wear. The clutch is technically a separate system but is often addressed alongside gearbox work as the two are removed together during a full repair.

A basic repair targeting a specific fault is the most affordable route. A full rebuild involves stripping the entire unit, replacing worn components, and reassembling to specification. A full replacement with a reconditioned unit is the most thorough option and carries the best warranty coverage.

Automatic Transmission Repair Costs

Repair Type	Complexity	Typical Cost Band
Fluid leak or seal repair	Low to medium	Low range
Solenoid replacement	Medium	Mid range
Clutch pack replacement	High	Mid to upper range
TCM replacement	High	Upper range
Full rebuild	Very high	Premium range
Full replacement, reconditioned unit	Very high	Upper to premium range
ATF flush and refill	Low	Low to mid range

Automatic gearboxes are significantly more expensive to repair than manuals because of their internal complexity. A modern automatic contains hundreds of individual components including planetary gear sets, torque converters, clutch packs, solenoid valves, hydraulic circuits, and an electronic control module. When one component fails, the diagnostic process alone is more involved, and the labour time for disassembly and reassembly is substantially longer.

Drivers who use automatic vehicles for regular school runs around Farnborough or longer commutes into Guildford tend to accumulate gear-change cycles faster than motorway drivers, which accelerates wear on clutch packs and solenoids over time. This makes fluid changes and regular servicing particularly valuable for automatic gearbox owners in urban and semi-urban areas.

DSG, Dual-Clutch, and CVT Gearbox Costs

DSG and dual-clutch gearboxes occupy the upper tier of repair complexity and cost. They combine the speed of a manual with the convenience of an automatic by using two separate clutches to pre-select the next gear. When the mechatronic unit, the combined electronic and hydraulic control system inside a DSG, develops a fault, the repair reflects both the specialist knowledge and the premium components required.

CVT transmissions, found in many hybrid and economy models, use a belt-and-pulley system instead of fixed gears. Belt wear and pulley degradation are the main failure points. The cost of a CVT repair or replacement reflects both the specialist parts required and the limited number of garages trained to work on them correctly.

Transmission Fluid and Diagnostic Costs

A transmission fluid change is the lowest-cost and highest-preventive-value service you can give your gearbox. ATF changes for automatics are more complex and more expensive than a straightforward manual gearbox oil swap, but both are a fraction of the cost of any mechanical repair. A diagnostic scan is similarly excellent value as a first step before any major work is approved, because it isolates the fault code and prevents misdiagnosis. Never authorise significant gearbox work without a proper diagnostic scan first.

What Affects the Cost of Transmission Repair?

Understanding what drives the final bill helps you have a far more confident conversation with a garage and makes it easier to judge whether a quote is reasonable. Five main factors determine where your repair cost will land.

1. Vehicle make and model. A Ford Fiesta or Vauxhall Astra gearbox is produced in large volumes, which means parts are widely available and relatively affordable. A BMW 5 Series or Mercedes E-Class gearbox involves specialist components that may need to be sourced from the manufacturer or imported, which drives both the parts cost and the waiting time upward. Luxury and performance vehicles consistently sit at the higher end of every repair category.
2. Transmission type. Automatic and DSG gearboxes are more expensive to repair than manual units across every category of work. More components, more labour time, and more specialist tools all contribute to the higher price. A manual gearbox repair is often the most cost-effective option if your car offers the choice and the fault permits it.
3. Severity and extent of damage. A targeted repair addressing one failed component costs significantly less than a full rebuild where multiple internal parts have degraded simultaneously. Catching a fault early, before a failing solenoid contaminates the fluid and causes clutch pack damage, can be the difference between a minor repair and a major one. This is why prompt diagnosis matters so much.
4. Parts source: OEM versus pattern parts. Original Equipment Manufacturer parts are made to the exact specification of the vehicle manufacturer and carry the highest quality assurance. They cost more than pattern parts, which are aftermarket alternatives that meet the specification but are not made by the original supplier. A reputable garage will discuss both options with you, particularly for older vehicles where OEM parts availability may be limited.
5. Location and labour rate. Garage labour rates in the South East of England, which includes Aldershot, Farnham, and Fleet, typically run higher than the national average due to higher operating costs. A specialist transmission garage may also charge a premium over a general workshop because of the expertise and tooling required. That premium is usually justified, particularly for automatic, DSG, or CVT repairs requiring specialist diagnostic equipment.

Repair, Rebuild, or Replace: What Is Right for Your Car?

When a garage confirms your transmission has a fault, you will typically be presented with three options. Understanding what each one delivers is the key to making the right call rather than simply accepting the first recommendation.

Targeted Repair

A targeted repair addresses the specific component that has failed, whether that is a solenoid, a seal, a bearing, or a clutch plate, without dismantling the entire gearbox unit. This is the most affordable option and the fastest to complete, often within 24 hours for straightforward faults. It makes the most sense when the gearbox is otherwise in good condition, the car has lower mileage, and the failed component is clearly identified through a proper diagnostic scan.

The limitation of a targeted repair is that it only covers what was found on the day. If the gearbox has broader underlying wear, that wear will surface again in the future. A reputable specialist will flag this during the assessment and help you weigh the risk honestly.

Full Rebuild or Recondition

A full rebuild involves stripping the gearbox completely, inspecting every internal component, replacing all worn or damaged parts, cleaning the casing, and reassembling to original specification. This is the most thorough form of repair and the closest outcome to a new gearbox without the cost of a complete unit replacement. Reputable UK gearbox specialists typically back a full recondition with a 12-month, unlimited-mileage warranty as standard.

This route takes longer, typically 3 to 7 days depending on parts availability, but delivers a transmission that should last 60,000 to 80,000 additional miles when properly maintained. For a vehicle in otherwise good condition, a rebuild is often the most cost-effective long-term solution.

Full Replacement

A full replacement swaps the existing gearbox for either a new unit, a reconditioned unit from a specialist, or a used unit from a salvage source. New units offer the longest service life but are the most expensive and are often only available through main dealers. Reconditioned units offer a strong balance of quality and value, typically backed by a 12-month warranty. Used or salvage units carry the highest risk and the shortest warranty coverage, sometimes as little as 3 months or 3,000 miles, and should only be considered where repair or reconditioning is not viable.

Under the Consumer Rights Act 2015, parts and workmanship on vehicle repairs are legally protected for up to six years, regardless of any shorter warranty offered in writing by the garage. A written warranty from the garage is a goodwill gesture. The Act is law, and it is important to understand that distinction before authorising any significant gearbox work.

Stat: Reconditioned gearboxes from reputable UK specialists typically carry a 12-month unlimited-mileage warranty and can represent savings of up to 40% versus a full service exchange price. A properly maintained rebuild is expected to deliver 60,000 to 80,000 miles of additional reliable service life.

Is It Worth Repairing a High-Mileage Car’s Gearbox?

This is the question that sits at the heart of most transmission repair conversations in the UK. The car has high mileage, the gearbox repair quote is substantial, and the question becomes whether to invest in fixing it or whether that money is better used towards a different vehicle altogether.

The most widely used practical guide among experienced mechanics and automotive community members is to avoid spending more than 50 to 60 percent of the car’s current market value on a single repair. If the car is worth £3,000 and the repair is £1,800, that is a genuinely difficult call. If the car is worth £6,000 and the repair is £1,800, it is a far more straightforward decision.

But the market value calculation is only part of the picture. The other part is what you know about the vehicle. A car with a full service history, no other known faults, and a reliable engine is a very different proposition from one that has had persistent issues across multiple systems. Spending on a gearbox repair for a car you trust and know the history of is often a better financial decision than replacing it with a used vehicle of unknown history at a significant premium.

Community experience from UK automotive forums consistently reinforces this point. One driver described spending £1,500 on a transmission rebuild for a car worth £2,500, justified on the grounds that every other aspect of the vehicle was solid and a replacement of equivalent specification would have cost at least £4,000 in the current used car market. Three additional years of reliable service proved the decision right.

The reverse is equally true. If the transmission fault has developed alongside other warning signs across the car, brakes, engine, suspension, or cooling, then the gearbox may simply be the most urgent fault in a longer queue. In that context, the honest calculation often points toward replacing the vehicle rather than investing further. A trusted local garage serving areas like Ash and Tongham can give you an honest assessment of the vehicle’s overall condition before you commit to any major repair.

5 Steps to Check if a Gearbox Repair Quote Is Fair

One of the most common anxieties around transmission repair in the UK is not the fault itself, but the quote. Drivers regularly report receiving quotes from two different specialists that differ by hundreds of pounds for what appears to be the same job. Knowing how to evaluate a quote gives you control over the situation.

1. Get at least three quotes. Contact at least two or three transmission specialists rather than general service garages. Transmission repair requires specialist tools and diagnostic equipment that general garages may not have, and the quotes you receive will reflect that expertise gap. A wide discrepancy between quotes is often a sign that one garage is proposing a full unit replacement where a targeted repair would suffice.
2. Ask for a written, itemised estimate. Any reputable garage should be willing to provide a written estimate that separates labour cost, parts cost, fluid cost, and diagnostic fees. A verbal quote over the phone is not enough for a repair of this scale. The written estimate also gives you a document to compare across garages and a reference point if the final invoice differs from what was agreed.
3. Clarify what parts are being used. Ask directly whether OEM or aftermarket parts will be fitted. Both have their place, but you should be making that choice consciously rather than discovering it after the fact. For newer vehicles or complex gearbox types such as DSG or CVT, OEM parts are generally the safer long-term investment.
4. Ask what the warranty covers and get it in writing. A standard benchmark for a good transmission repair warranty is 12 months and unlimited mileage. Ask whether the warranty covers both parts and labour. Ask what circumstances would make the warranty void. Get the answer in writing before any work begins. A garage unwilling to provide warranty terms in writing is a garage worth walking away from.
5. Know your legal rights before you sign anything. Under the Consumer Rights Act 2015, work on your vehicle must be carried out with reasonable care and skill, and any parts fitted must be of satisfactory quality and fit for purpose. These legal protections apply for up to six years from the date of repair, regardless of what any written warranty document says. This legislation is your foundation for a claim if a repair fails within a reasonable timeframe and the garage disputes liability.

How to Make Your Transmission Last Longer

The most expensive transmission repair is the one that could have been prevented. With consistent, straightforward maintenance habits, a well-cared-for gearbox can last the full lifespan of the vehicle. Most modern gearboxes are designed to reach 150,000 to 200,000 miles before major work is required, but that figure assumes the fluid is changed regularly, the vehicle is driven sensibly, and early warning signs are acted on rather than ignored.

Change the fluid on schedule. Automatic transmission fluid should be changed every 30,000 to 60,000 miles as a general guide, and manual gearbox oil every 30,000 to 50,000 miles. Always check your vehicle manufacturer’s recommendation first. Degraded fluid loses its ability to lubricate, cool, and maintain hydraulic pressure, and that degradation is one of the leading causes of avoidable gearbox damage.

Do not believe the “lifetime fluid” label. Many modern sealed gearboxes on VAG and BMW platform vehicles carry a “filled for life” designation on the transmission fluid. This does not mean the fluid never degrades. Transmission specialists consistently recommend changing this fluid at 60,000 to 70,000 miles regardless of the label, particularly if the vehicle is used in stop-start conditions such as commuting through Aldershot or short journeys around Farnborough.

Warm up before working the gearbox hard. Cold transmission fluid is thicker and flows less freely, meaning the first few minutes of driving after a cold start offer reduced lubrication. Gentle driving during that warm-up period reduces early-morning wear significantly, particularly on automatic clutch packs and solenoid valves.

Avoid aggressive gear engagement. Snatching gears, pulling away sharply from standstill, and engaging reverse without coming to a complete stop all place unnecessary stress on transmission components. These habits are particularly damaging to automatic and DSG gearboxes where the transition between clutch packs is electronically managed and calibrated for smooth, progressive input.

Check for leaks regularly. A quick glance at the ground beneath your car after it has been parked overnight takes seconds. A small red or amber-coloured puddle beneath the gearbox area is an early leak that is straightforward and inexpensive to fix at that stage. Left unchecked, even a minor leak can drop fluid levels to the point where internal components begin running dry.

Include the transmission in your regular service. A thorough service that checks fluid levels, inspects for leaks, and reads diagnostic fault codes catches transmission problems at their earliest and cheapest stage. Drivers in Fleet, North Camp, and across north Hampshire and Surrey who keep their vehicles on a consistent service schedule consistently avoid the larger repair bills that follow from deferred maintenance.

Gearbox Type	Recommended Fluid Change Interval	Key Benefit
Manual gearbox	Every 30,000 to 50,000 miles	Prevents bearing and synchro wear
Automatic, ATF	Every 30,000 to 60,000 miles	Maintains hydraulic pressure and clutch pack life
DSG or dual-clutch	Every 40,000 miles despite “lifetime” label	Prevents mechatronic unit degradation
CVT	Every 30,000 to 60,000 miles	Protects belt and pulley surfaces

Stat: A transmission fluid change costs a fraction of any mechanical repair and is the single most effective preventive measure available to UK drivers. Changing ATF every 60,000 to 70,000 miles can significantly extend the working life of an automatic gearbox regardless of manufacturer labelling.

Transmission issues rarely develop in isolation. If your vehicle has been pulling, vibrating, or making noises that you cannot quite place, it is worth establishing whether what you are feeling comes from the gearbox or from the braking system. Brakes that squeak at low speed can sometimes produce sensations that overlap with drivetrain or gearbox symptoms, and separating the two through a proper inspection saves significant diagnostic time and cost.

Conclusion

That clunk in the gear lever. The hesitation at the roundabout. The faint smell you have been trying to rationalise for two weeks. All of these are your transmission telling you something before the situation becomes urgent. The drivers who act early, who book a diagnostic when the first sign appears rather than waiting for the second or third, are almost always the ones who pay the least and drive away with the most life left in their vehicle.

Transmission repair in the UK is genuinely complex and genuinely expensive at the severe end of the spectrum. But the vast majority of gearbox problems, particularly fluid degradation, minor leaks, solenoid faults, and early-stage bearing wear, are entirely manageable when they are caught at the right time. The warning signs are clear, the options are well-defined, and the tools to evaluate a fair quote are now in your hands.

Whether you drive through Ash Vale on your morning commute, cover regular miles between Aldershot and the M3, or keep a higher-mileage vehicle that you are not ready to part with, the same principle applies. A small investment in knowledge and early action is always worth more than a large bill paid in a crisis.

Frequently Asked Questions

How much does transmission repair cost in the UK?

Transmission repair costs in the UK vary significantly depending on the type of gearbox, the severity of the fault, and the labour rates in your area. Minor repairs such as a fluid leak or solenoid replacement sit at the lower end of the scale, while a full rebuild or replacement of an automatic or DSG gearbox can reach the upper range. The best starting point is always a diagnostic scan, which clarifies exactly what is wrong before any larger work is approved.

What are the early warning signs of gearbox failure?

The most common early signs are slipping or jumping gears, a hesitation or delay when pulling away, grinding or whining noises during gear changes, a burning smell from the bonnet or cabin, a red or brown fluid leak beneath the car, and a dashboard warning light such as the check engine or transmission symbol. Any single sign warrants an inspection. Two or more appearing together is a reason to act without delay.

Is it worth repairing a gearbox on a high-mileage car?

It depends on the cost of the repair relative to the vehicle’s current market value and its overall condition. A widely used practical guide is to avoid spending more than 50 to 60 percent of the car’s market value on a single repair. However, a vehicle with a strong service history, a reliable engine, and no other significant faults is often worth investing in, particularly given the current premium on quality used replacements.

How long does a gearbox repair take?

A targeted repair addressing a specific fault such as a seal or solenoid can often be completed within 24 hours. A full gearbox rebuild typically takes 3 to 7 days depending on parts availability. A replacement using a reconditioned unit can often be completed in 1 to 3 days if the right unit is in stock. Always ask for an estimated timescale in writing so you can arrange alternative transport if needed.

What is the difference between a gearbox repair, rebuild, and replacement?

A repair targets and fixes a specific failed component without dismantling the entire unit. A rebuild strips the gearbox completely, replaces all worn internal components, and reassembles it to specification, essentially restoring it to near-new condition. A replacement swaps the complete unit for a new, reconditioned, or used gearbox. Each option suits a different level of damage and a different budget.

Can I drive with a faulty transmission?

Driving with a confirmed transmission fault is not recommended. Slipping gears can cause a sudden loss of drive, which is a safety risk particularly at speed. If the transmission has entered limp mode, the vehicle is protecting itself from further damage and continuing to drive it will worsen the situation and increase the eventual repair cost. If you notice any of the warning signs described in this guide, book a diagnostic inspection without delay.

How often should transmission fluid be changed?

For automatic transmissions, the general recommendation is every 30,000 to 60,000 miles. Manual gearboxes typically require an oil change every 30,000 to 50,000 miles. DSG gearboxes, despite often being labelled as lifetime fill, should have their fluid changed every 40,000 miles as a precaution. Always check your vehicle manufacturer’s handbook for the specific interval recommended for your make and model.

Does a reconditioned gearbox come with a warranty?

A reputable reconditioned gearbox should carry a 12-month, unlimited-mileage warranty as a minimum. Some specialists offer 24 months. Used or salvage units typically carry much shorter cover, sometimes as little as 3 months or 3,000 miles. Always obtain warranty terms in writing before authorising any work, and remember that the Consumer Rights Act 2015 provides up to six years of legal protection on parts and workmanship regardless of what the written warranty document states.

What is limp mode and what should I do if my car enters it?

Limp mode is a protective state activated by the vehicle’s onboard computer when it detects a serious fault, including a transmission fault. In limp mode, the gearbox locks into a single low gear to prevent further internal damage. The car will still move but performance is severely restricted. If your vehicle enters limp mode, do not continue driving normally. Pull over safely, switch the engine off and back on to see if the mode clears, and then drive directly to a garage for a diagnostic scan. Do not attempt a long journey while in limp mode.
