What it is & what it does

A torque converter is a fluid coupling between the engine and a conventional automatic gearbox — it lets the engine keep spinning while the car is stopped, multiplies torque as you pull away, and locks up at cruise for efficiency.

It’s why a traditional auto creeps forward at idle and takes off so smoothly.

Signs of trouble & how we help

A worn converter (or its lock-up clutch) causes shudder at light throttle around 60–100 km/h, slipping, overheating transmission fluid, or a rattle. Degraded fluid accelerates all of it — the fluid service protects the converter too.

We read transmission data and test for converter shudder vs other causes before recommending work.
