What it is
A small workshop that diagnoses gearbox faults, removes and refits gearboxes, and repairs or rebuilds manual and automatic transmissions. Many also supply reconditioned units and fit clutches.
Your first three steps
- Price up a small unit with a ramp or lift, and check the permitted use with the landlord and council
- Work out which makes and gearbox types you will specialise in, then line up parts and reconditioning suppliers
- Visit local independent garages and offer to take on their gearbox jobs at trade rates
Who pays
Private drivers with a failing gearbox, independent garages that sub out transmission work, and small van fleets.
How it makes money
Fixed or quoted prices for diagnosis, repair, rebuild and fit, plus parts margin. Regular work from local garages helps fill quieter weeks.
Skills that help

- Fault diagnosis
- Clear quoting and honest customer communication
Watch out for

- Consumer law: work must be done with reasonable care and skill, so keep clear records and offer a written warranty
