Service4Service repairs automatic gearboxes for drivers right across Guildford, and automatic gearboxes are all we focus on. Over 18 years we have completed more than 20,000 gearbox rebuilds, from single-component faults to full transmission overhauls.
Modern automatics are complicated. A DSG or dual-clutch box relies on a mechatronic unit, a CVT on a belt and pulleys, and a conventional automatic on its valve body and solenoids. A general garage can read a fault code; we find out why it was triggered. Every job starts with a full diagnostic, including a fluid check, live shift analysis, fault code reading and a sensor and solenoid assessment.
If your car can't be driven, we can arrange collection or recovery from your home or workplace anywhere in Guildford, from Stoughton and Burpham to Merrow and Onslow Village, subject to availability, and keep you updated until it's back with you.
Serving every Guildford postcode, from the town centre to the surrounding villages.
No need to drive a struggling gearbox across town. Subject to availability, we collect from your home or workplace and bring the car back once it's fixed.

Covering GU1, GU2, GU3, GU4 and GU5
Guildford is tough on automatic transmissions. Peak-time queues on the A3 Guildford bypass, the town-centre gyratory, and slow traffic on the A31 Hog's Back, the A281 towards Shalford and Bramley, and the A320 towards Woking all mean plenty of crawling and stop-start driving. That is exactly the kind of use that wears dual-clutch packs and overheats transmission fluid fastest.
If your DSG judders when pulling away in queues, your CVT whines climbing out of the town centre, or your automatic hesitates when joining the A3, get it checked early. A targeted repair now usually costs far less than a rebuild later.
Gearbox faults rarely fix themselves and usually get worse if ignored.

It is best not to. Limp mode restricts the car to protect the transmission after a fault is detected, often caused by low fluid, a faulty solenoid or a wiring problem. Driving on it can turn a small repair into a larger one, so arrange a diagnosis or collection instead.
No. We explain the diagnostic findings and confirmed costs before proceeding, and if further work is identified we call you first. No additional repair is carried out without your authorisation.
