Estimates for a small start in Canada, not guarantees.

What it is

A small shop in a rented unit or bay that diagnoses transmission problems, does fluid services and clutch work, and rebuilds or swaps automatic and manual gearboxes for cars, vans and light trucks.

Your first three steps

  1. Price up a small unit with a hoist or lift bay and check the zoning allows auto repair
  2. Get a quote for core equipment (lift, transmission jack, scan tool, flush machine) and ask suppliers about parts accounts
  3. Visit nearby independent garages and tow companies to introduce yourself and arrange referrals
Who pays

Local drivers, small businesses with work vans, and independent garages that don't do transmission work themselves.

How it makes money

Fixed or quoted price per job, covering labour, parts and a warranty. Smaller jobs like fluid services and diagnostics bring in steady work between bigger rebuilds.
