Transmission and Gearbox Repair
Transmission and gearbox work covers everything that carries power from the engine to the wheels: manual gearboxes, automatics, CVT and DCT units, differentials, drive shafts and CV joints. Symptoms include jerky or delayed gear changes, difficulty selecting gears, whining, slipping and clicking on turns. Work ranges from an oil change to a full overhaul, so diagnosis comes first and the repair is quoted from what it finds.

Workshop
How a job runs
Same four steps every time, whether we come to you or you come to us.
Describe the symptom
You do not need to know the cause. Tell us what you hear, feel or smell and when it happens.
We inspect it
At your location where the job allows, otherwise at a workshop with the right equipment.
You get a price
Parts and labour, itemised, before anything is taken apart. You decide whether to go ahead.
We fix it
Parts matched to your exact vehicle. The old ones come back to you if you want them.
At your door, or in the workshop?
Some of this work needs equipment that does not travel. Here is the split for this category.
How we work
Four things we do on every job, in every category.
Diagnosis before quote
We find the fault first. A price given over the phone for a noise nobody has heard is a guess.
The price is agreed first
You approve the work and the cost before a spanner is picked up. Extra work means another call.
Parts you can check
We tell you whether a part is genuine, OEM, aftermarket or used, and what each one costs.
Old parts returned
Ask and we will hand back whatever we replaced. It is the simplest proof that the job was done.
