Common questions

Frequently Asked Questions

Understanding your vehicle's maintenance needs, and addressing issues promptly are key to maintaining your car's performance and reliability. If you have specific questions about your vehicle or a repair issue, don't hesitate to call Service4Service on 0808 164 0418 for guidance.

The cost of a gearbox repair depends on the vehicle, the gearbox type, the fault, and whether a targeted repair, rebuild or replacement unit is needed. A targeted repair is usually the cheapest option, and a rebuild costs a fraction of a new gearbox. Service4Service runs a full diagnostic first and gives you a complete quote to approve before any work begins.

Rebuilding is usually the better option when the gearbox casing and main components are sound. A gearbox rebuild, also called reconditioning or refurbishment, strips the gearbox down, replaces worn parts and tests it to manufacturer specification, at a fraction of the cost of a new unit. Replacement is only recommended when a repair or rebuild won't restore reliable performance.

Many automatic gearboxes last well over 100,000 miles, and some last the life of the car. Lifespan depends on the gearbox type, how the car is driven and whether the transmission fluid has been kept in good condition. Heavy towing, frequent short stop-start journeys and ignored warning signs all shorten it.

Common signs your automatic gearbox needs repair include slipping between gears, delayed engagement, jerky or harsh gear changes, whining or grinding noises, fluid leaks, a burning smell and a transmission warning light. Catching these early usually keeps the repair cost down, so book a diagnostic as soon as you notice them.

An automatic car that won't go into gear usually has low or degraded transmission fluid, a faulty gear selector or cable, a failed solenoid or valve body, a transmission control unit fault, or a brake switch fault stopping the selector moving out of Park. A diagnostic will show which it is before any parts are replaced.

A whining automatic gearbox usually points to low or worn transmission fluid, a failing fluid pump, worn bearings, or wear in the torque converter or planetary gears. Grinding or clunking can mean more advanced internal wear. Gearbox noise is an early warning sign, so get it diagnosed before it becomes a bigger repair.

An automatic gearbox slips when it can't hold a gear, so the engine revs rise but the car doesn't accelerate as it should. Common causes are low or burnt transmission fluid, worn clutch packs or bands, faulty solenoids or valve body faults, and a failing torque converter. Slipping that's worse when the gearbox is hot usually points to worn fluid or internal wear.

No. A gearbox warning light means the transmission control system has detected a fault, and continuing to drive risks turning a minor repair into a much bigger one. If the light is on or the car feels different to drive, have it checked as soon as possible. Service4Service can arrange collection or recovery, subject to availability.

Jerking or juddering when changing gear usually points to worn clutch packs, a failing solenoid, degraded transmission fluid or a torque converter fault. It's especially common in DSG and dual-clutch gearboxes, where worn or contaminated clutches cause judder when pulling away. Left undiagnosed it typically gets worse, so have it checked before it leads to a bigger repair.

Service4Service repairs, rebuilds, reconditions and replaces automatic gearboxes of all types, including DSG, CVT, Powershift and other dual-clutch gearboxes, and hybrid transmissions. Work includes full diagnostics, mechatronic unit repairs, valve body and solenoid repairs, clutch replacement and reprogramming, across all major manufacturers.

Yes. Every automatic gearbox repair and rebuild is guaranteed for 12 months or 12,000 miles on parts and labour. Service4Service fits OEM (original equipment manufacturer) or manufacturer warranty-approved parts, meaning parts made by or for the vehicle maker, so the work protects your existing manufacturer's warranty.

Limp mode is a safety feature that activates when the transmission control system detects a fault. It restricts the car to one or two gears and reduced speed to prevent further damage. Common causes include low transmission fluid, a faulty solenoid, a sensor or wiring fault, or a control unit fault. Have it diagnosed rather than continuing to drive on it.
