What it is

A workshop with one or two lifts where you diagnose transmission problems, replace or rebuild gearboxes, and do fluid services and clutch work for cars, trucks and vans.

Your first three steps

  1. Price out a small leased bay or unit in your area and check that zoning allows auto repair
  2. Get quotes for a lift, transmission jack, diagnostic scan tools and general liability and garage insurance
  3. Visit independent garages and tow companies nearby to offer your shop as their transmission referral partner
Who pays

Local drivers, small fleets and tradespeople with work vans, plus independent garages that send over jobs they don't want to handle.

How it makes money

Labor and parts on each repair or rebuild, plus fluid services and diagnostics. Rebuilds are larger tickets, and repeat business comes from referrals and local garages.

Skills that help
  • Transmission diagnosis and rebuilding (ASE certification is a plus)
  • Estimating jobs clearly and honestly
  • Customer service and explaining repairs in plain language
Watch out for
  • Check your state for auto repair shop registration or licensing, and any written estimate rules
  • Check city or county zoning and your local business license requirements
  • Used fluid, filters and old parts have disposal rules, so check with your state environmental agency
  • Garage liability and garagekeepers insurance to cover customers' vehicles, and workers' compensation once you hire
  • Warranty claims and comebacks on rebuilds, so set clear written warranty terms
