What does a torque converter do?
It sits between the engine and automatic gearbox and transfers power using transmission fluid.
At cruising speed, a lock-up clutch can connect more directly to improve efficiency.
What does torque-converter shudder feel like?
The vehicle may vibrate as though it is driving over a rough road at a steady speed.
It often appears under light acceleration when the lock-up clutch is applying.
What other symptoms can appear?
- Revs rise without matching acceleration
- Slow pull-away
- The engine stalls when a gear is selected
- The gearbox overheats
- Whining or rattling
- Metallic debris in fluid
- A transmission fault code
Can fluid cause converter shudder?
Incorrect, degraded or contaminated fluid can affect lock-up operation.
A fluid service cannot repair damaged converter parts.
Can a torque converter be repaired?
Specialist repair may involve rebuilding or replacing the converter.
The gearbox and cooler should also be checked for contamination.
Can I keep driving?
Continued shudder or slipping creates heat and may spread debris. Stop if the car loses drive, stalls or overheats.
