Estimates for a small start in Australia, not guarantees.

What it is

A back-of-house rebuild service. Garages remove the gearbox and send it to you, and you strip, rebuild, test and return it. You do not deal with the public, so you need less shopfront and less marketing.

Your first three steps

  1. Choose a few gearbox types you can rebuild well and work out your price and turnaround for each
  2. Set up a small workshop or shared unit with a bench, press, parts washer and test equipment
  3. Offer trial rebuilds to three or four local garages and ask for repeat work
Who pays

Independent mechanics, tyre and service centres, and small fleet workshops without in-house transmission skills.

How it makes money

Rebuild price per unit plus parts, often at trade rates, with repeat work from a handful of regular garages.

Skills that help

  • Reliable turnaround times

  • Relying on a few garages for most of your work
  • Safe disposal of used oil, solvents and parts washer waste, check local rules
  • Council approval if you use a shed or home-based premises
