Torque converter

The fluid coupling between engine and gearbox that lets the engine idle with the car stationary, and locks up at cruise for efficiency.

Also called converter, TC.

How you know it is this

  • A shudder at light throttle around 60–80 km/h — the classic lock-up clutch judder
  • Stalling as the car comes to a stop
  • Slipping under load with a gearbox that shifts cleanly
  • Overheating gearbox fluid

Worth knowing before you buy

  • The judder at cruise is the lock-up clutch and is the most recognisable converter symptom there is.
  • When a converter fails it sends its debris through the whole gearbox. That is why a converter and a rebuild are so often quoted together.
  • Always replaced with a rebuilt gearbox. Reusing the old one reintroduces the contamination that killed the box.
  • The gearbox has to come out either way, so the labour is the same as a gearbox job.

What we need to quote it. The gearbox code and the engine code. The chassis number settles the generation, the body and usually the engine in seventeen characters — it is on your mulkiya. A photograph of the old part helps where there is more than one version.
