Specialist Gearbox Repairs in London

From DSG and Powershift faults to CVT and hybrid transmission problems, our London repair centres diagnose, repair and rebuild every major gearbox type, with every job backed by a 12-month/12,000-mile warranty on parts and labour.

Gearbox Replacement

A replacement isn't always the first option. We always check whether a repair or reconditioned unit could fix the fault first, as it's often the more cost-effective route. Where replacement is genuinely the right call, we fit quality units backed by our 12-month/12,000-mile warranty.

With 18+ years' experience and over 20,000 completed rebuilds, we've helped thousands of London drivers make the right call on repair versus replacement, with no pressure towards the more expensive option.
