Suzuki CVT, AGS automated-manual, conventional automatic and manual gearboxes can develop valve-body, actuator, clutch, solenoid, torque-converter, bearing or selector faults. Shuddering, harsh changes, delayed drive, warning messages or unusual noises should be diagnosed early. We identify the fault before work begins.



Tell us what your Suzuki is doing and we will point you in the right direction. CVT, AGS, automatic, manual gearbox, clutch and ALLGRIP diagnostics and repairs 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.
Suzuki models use CVT systems, AGS automated manuals, conventional four/six-speed automatics, five/six-speed manuals, hybrid transaxles and electric drive units. We identify the exact transmission fitted before recommending any repair.
We collect your Suzuki 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 repair Suzuki CVT, AGS, conventional automatic, manual gearbox, clutch and ALLGRIP systems across London, with savings of up to 60% on full replacement costs. Work uses approved or equivalent-quality parts and is completed by qualified transmission technicians. Collection and delivery is available.
Suzuki transmissions vary by model and year, but CVTs, AGS automated manuals, conventional automatics, manuals and ALLGRIP drivetrains each develop recognisable fault patterns. Common faults reported by London customers include:
We use Suzuki-compatible diagnostics to identify the gearbox and fault. You receive a fixed price for the required CVT, AGS, automatic, manual, clutch, rebuild or replacement work.
We cover Suzuki hatchbacks, estates, crossovers, SUVs, 4x4s, older vehicles and imports. The exact transmission is confirmed from the registration, VIN and gearbox code.
Hybrid and electric models: Swace Hybrid uses a hybrid e-CVT transaxle, while Across uses a plug-in hybrid transaxle with electric AWD. The e VITARA uses electric drive units rather than a conventional gearbox. Please call with the registration, VIN or gearbox code so we can confirm the exact drivetrain before booking.
We confirm the repair warranty, document the work and explain any manufacturer or third-party authorisation requirements before work begins.

Service4Service London carries out Suzuki 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 CVTs, AGS automated manuals, four/six-speed automatics, five/six-speed manuals, clutches, differentials and Suzuki ALLGRIP systems.
Where a repair is not economical, we can supply and fit a quality reconditioned Suzuki gearbox as an alternative to replacing the transmission with an untested used unit. A reconditioned unit is stripped, inspected, rebuilt to specification and tested before fitting.
We also carry out CVT valve-body, belt, pulley, torque-converter, AGS actuator, clutch, flywheel, solenoid, selector, bearing, differential, transfer-case and transmission-control repairs alongside full rebuilds.
We collect and return Suzuki vehicles for gearbox repair from across Central, North, South, East and West London, including Croydon, Enfield, Wembley, Bromley, Richmond and surrounding areas.
If your Suzuki cannot be driven, vehicle recovery may also be available. Call 02039056741 to arrange collection or request a fixed quotation.
Many Suzuki owners expect a routine service, but CVT shudder, AGS judder, harsh engagement, delayed selection, rev flare, slipping, warning messages or whining mean the vehicle also needs diagnosis.
At Service4Service London, we specialise in Suzuki CVT and AGS diagnosis, conventional automatic repair, manual gearbox and clutch work, ALLGRIP driveline repairs and complete gearbox rebuilds.
For suitable Suzuki gearbox repairs, we use the correct oil, fluid, filter and service parts. Fresh fluid alone cannot repair a worn CVT belt or pulley, AGS actuator, torque converter, valve body, bearings, selector or control fault.
If your Suzuki 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 02039056741Delayed engagement, harsh shifting, CVT shudder, rev flare, selector faults, warning messages or loss of drive can point to hydraulic, electrical, control or internal problems.
We diagnose CVT valve-body, belt and pulley faults, AGS actuator problems, conventional automatic faults, manual gearbox wear, selectors, differentials and Suzuki ALLGRIP driveline problems across the range.

Gearbox repair is all we do. Here is what that means for you.
CVTs, AGS automated manuals, conventional automatics, manuals, clutches, flywheels, differentials and Suzuki ALLGRIP systems are within our specialist workload.
Component repair can cost far less than replacing the complete gearbox. The saving depends on the model, unit, parts 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 Suzuki is not driveable, ask us about recovery options so the vehicle can reach us safely for inspection and repair.
Common questions from Suzuki owners in London, answered by our transmission specialists.
Suzuki CVT shudder, rev flare or harsh engagement can be caused by valve-body pressure faults, worn belt or pulley surfaces, torque-converter lock-up problems, solenoid faults, contaminated fluid or bearing damage. AGS judder can involve the clutch, actuator or calibration. The gearbox should be tested before parts are replaced.
A warning can be caused by CVT pressure or slip, AGS actuator or clutch faults, valve-body, solenoid, selector, speed-sensor, overheating, wiring, control-unit or internal faults. The vehicle may enter emergency mode, so prompt diagnosis is recommended.
It depends on the model, gearbox and failure. A CVT valve-body or belt/pulley fault, AGS actuator repair, torque-converter repair, conventional automatic repair, manual bearing replacement, clutch repair and full gearbox rebuild are very different jobs. We provide a fixed quotation before work begins. Call 02039056741 for an initial indication based on the model, year and symptoms.
A warning message, CVT slip, rev 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 CVT belts and pulleys, AGS clutches or actuators, gears, bearings, pumps, valve bodies, torque converters, ALLGRIP components or differentials. Recovery may be arranged when the vehicle is not safe to drive.
Many Suzuki transmission faults can be repaired without replacing the complete unit. Valve bodies, pressure solenoids, torque converters, CVT belts and pulleys, AGS actuators, clutches, selectors, bearings and conventional automatic components may be repairable individually. Where internal damage is extensive, reconditioning the original gearbox is often more economical than fitting an untested used unit.
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 a manufacturer, aftermarket or third-party warranty, check the claim-authorisation requirements before work begins.
Common faults include CVT shudder, valve-body pressure failure, solenoid faults, belt or pulley wear, AGS clutch or actuator problems, delayed selection, harsh engagement, torque-converter lock-up faults, fluid leaks, selector faults and bearing damage. The correct repair depends on the exact transmission and drivetrain codes rather than the model name alone.
