Mitsubishi CVT, automatic, Twin Clutch SST, manual, hybrid and 4WD drivetrains can develop recognisable warning signs when a clutch, valve body, solenoid, torque converter, control unit, bearing or internal component begins to fail. If your Mitsubishi is changing harshly, shuddering, slipping, refusing to select drive or reverse, displaying a transmission warning, or producing whining and clunking noises, early diagnosis can prevent further damage. Our technicians specialise in Mitsubishi gearbox, clutch and driveline repairs and identify the fault before any work begins.



Tell us what your Mitsubishi is doing and we will point you in the right direction. CVT, INVECS automatic, Twin Clutch SST, manual, clutch, S-AWC, 4WD and PHEV drive-unit diagnostics are covered.
Not sure what the fault is? Describe the symptoms and we will help identify the likely next step.
* Timeframes are estimates based on typical jobs. Actual turnaround depends on the specific fault, parts availability and current workshop capacity. We confirm a firm timeframe when you book.
Mitsubishi models use CVT and INVECS systems, Twin Clutch SST performance gearboxes, conventional automatics, manuals, 4WD/S-AWC drivetrains and PHEV drive units. We identify the exact transmission fitted before recommending any repair.
We collect your Mitsubishi from home or work anywhere in London, carry out the gearbox repair, and bring it back once the job is done. No drop-off required.

We work on a wide range of Mitsubishi CVT, INVECS automatic, Twin Clutch SST, conventional automatic, manual, clutch, S-AWC, 4WD and PHEV drive systems across London, with savings of up to 60% on main dealer prices. Every job uses manufacturer-approved or equivalent-quality parts and is completed by qualified transmission technicians. Collection and delivery can also be arranged where applicable.
Mitsubishi transmissions vary by model and year, but CVT units, conventional automatics, Twin Clutch SST gearboxes, manuals and 4WD drivetrains each develop recognisable fault patterns. Common faults reported by London customers include:
We use Mitsubishi-compatible diagnostic equipment to identify the gearbox and drivetrain fitted and the cause of the fault. You receive a fixed price for the exact repair required, whether that is CVT pressure or valve-body work, SST clutch or mechatronic repair, torque-converter repair, manual gearbox work, S-AWC driveline repair, full rebuild or replacement unit.
We cover Mitsubishi hatchbacks, saloons, estates, SUVs, pickups, MPVs, performance cars and electrified models commonly found in the UK, together with older and imported vehicles. Exact transmission and drivetrain availability is confirmed from the registration, VIN and gearbox code.
Hybrid and electric models: the Outlander PHEV and Eclipse Cross PHEV use electric motors and dedicated hybrid transaxles rather than a conventional automatic gearbox, while the i-MiEV uses an electric reduction drive. Please call with the registration or VIN so we can confirm whether the required hybrid or electric-drive work is within our service before booking.
Where Block Exemption rules apply, you are entitled to use a qualified independent specialist without automatically losing the manufacturer warranty, provided the correct-quality parts and procedures are used. We document the work completed and explain the warranty supplied with the repair.

Service4Service London carries out Mitsubishi gearbox repairs and transmission reconditioning across London and surrounding areas. Every job is completed by qualified transmission technicians using the correct specification parts and fluids.
We work on Mitsubishi CVT and INVECS systems, Twin Clutch SST gearboxes, conventional automatics, manuals, clutches, S-AWC and 4WD systems, transfer cases, differentials and PHEV drive units.
Where a repair is not economical, we can supply and fit a quality reconditioned Mitsubishi gearbox as an alternative to main dealer replacement pricing. A reconditioned unit is stripped, inspected, rebuilt to specification and tested before fitting.
We also carry out CVT valve-body and pressure repairs, solenoid, actuator, SST clutch and mechatronic, torque-converter, bearing, differential, transfer-case and transmission-control repairs alongside full rebuilds.
We collect and return Mitsubishi vehicles for gearbox repair from across Central, North, South, East and West London, including Croydon, Enfield, Wembley, Bromley, Richmond and surrounding areas.
If your Mitsubishi cannot be driven, vehicle recovery may also be available. Call 02039056741 to arrange collection or request a fixed quotation.
Many Mitsubishi owners book in expecting a routine gearbox service, but the reason they called is often that the transmission is already showing signs of a fault: harsh shifting, CVT flare or judder, SST clutch shudder, delayed selection, slipping, a warning light, whining or unusual noises. In those cases the vehicle needs diagnosis as well as fresh fluid.
At Service4Service London, we specialise in Mitsubishi CVT and INVECS diagnosis, conventional automatic repair, Twin Clutch SST clutch and mechatronic work, manual gearbox and clutch repairs, S-AWC and 4WD drivetrains, PHEV drive units and complete rebuilds.
As part of a suitable Mitsubishi gearbox or drivetrain repair, we use the correct specification oil, fluid, filter or service components for the unit fitted. Fresh fluid alone will not repair a worn CVT belt or pulley, damaged SST clutch, failing torque converter, valve-body wear, actuator faults, worn bearings or an electronic control problem.
If your Mitsubishi gearbox does not feel right, early diagnostics can often reduce consequential damage and avoid replacing parts that are not responsible for the fault.
We carry out the appropriate work after identifying the transmission and the fault. If servicing is all the vehicle needs, that is what we quote for. If testing finds a more serious issue, you receive a fixed quote before any repair begins.
Call 02039056741When a Mitsubishi gearbox or drivetrain fault appears, the right diagnosis matters. Delayed engagement, harsh shifting, CVT judder or flare, SST clutch shudder, torque-converter vibration, warning messages or loss of drive can each point to different hydraulic, electrical, control or internal problems.
We diagnose CVT pressure and pulley faults, conventional automatic valve-body and torque-converter problems, Twin Clutch SST mechatronic and clutch issues, manual gearbox wear, selectors, S-AWC differentials, transfer cases and PHEV drive-unit problems across the Mitsubishi range.

Gearbox repair is all we do. Here is what that means for you.
CVT and INVECS units, Twin Clutch SST gearboxes, conventional automatics, manuals, clutches, S-AWC and 4WD systems, transfer cases, differentials and PHEV drive units are within our specialist workload.
Approved or equivalent-quality parts and specialist transmission work without main dealer labour rates. The exact saving depends on the model, gearbox and fault.
We find the fault, give you a fixed price, and only start work when you have approved it. The £30 diagnostic fee comes off your repair bill if you go ahead.
We collect from home or work across London and return the car once the job is done. No need to arrange a drop-off.
The warranty supplied is confirmed on your quotation and relates to the repair or reconditioned unit fitted. We document the work completed.
If your Mitsubishi is not driveable, ask us about recovery options so the vehicle can reach us safely for inspection and repair.
Common questions from Mitsubishi owners in London, answered by our transmission specialists.
Mitsubishi shudder, hesitation, slipping or harsh shifting can be caused by torque-converter lock-up faults, valve-body wear, pressure-control solenoids, contaminated fluid, adaptation errors, SST clutch wear, mechatronic faults, CVT belt or pulley wear, actuator problems or internal bearing damage. The gearbox and drivetrain should be tested before parts are replaced.
A gearbox warning can be triggered by a valve-body or solenoid issue, SST mechatronic or clutch problem, CVT pressure fault, selector or actuator fault, overheating, torque-converter issue, wiring problem, control-module error or internal slip. The vehicle may enter reduced-power mode, so diagnostic testing should be carried out promptly.
It depends on the model, gearbox and failure. A clutch repair, synchro or bearing replacement, solenoid or valve-body repair, torque converter, SST mechatronic fault, CVT repair, 4WD driveline issue and full gearbox rebuild are very different jobs. Our prices can be up to 60% less than main dealer pricing, depending on the repair. We provide a fixed quotation before work begins. Call 02039056741 for an initial indication based on the model, year and symptoms.
A warning light, SST clutch slip, CVT flare, loss of drive, delayed engagement, overheating, whining, grinding or heavy clunking should not be ignored. Driving under load with an active fault can damage clutches, gears, bearings, pumps, valve bodies, torque converters, CVT components, S-AWC parts, PHEV drive units or differentials. Recovery may be arranged when the vehicle is not safe to drive.
Many Mitsubishi transmission faults can be repaired without replacing the complete unit. Selectors, actuators, SST clutch components, solenoids, valve bodies, torque converters, CVT components and differentials may be repairable individually. Where internal damage is extensive, reconditioning the original gearbox is often more economical than fitting a replacement unit. We diagnose first and recommend the most sensible option.
Using an independent specialist does not automatically cancel a vehicle warranty. The position depends on the vehicle, age, warranty terms, parts used and whether the repair is connected to a warranty claim. For a vehicle covered by an aftermarket or third-party warranty, check the claim-authorisation requirements before work begins.
Common faults include torque-converter shudder, valve-body and solenoid wear, delayed drive, harsh shifts, fluid leaks, SST clutch judder, mechatronic faults, CVT flare or pressure loss, actuator problems, selector faults, S-AWC driveline wear and internal bearing damage. The correct repair depends on the exact transmission and drivetrain codes rather than the model name alone.
