Torque converter
Transfers engine torque through fluid in a compatible automatic gearbox.
Between engine and torque-converter automatic transmission.
Pump, turbine and stator manage fluid torque transfer; a lockup clutch can reduce slip.
Two fans facing each other, coupled through moving fluid.
Shudder or delayed drive needs checks of control, fluid and the wider transmission system.
Use the exact gearbox and axle service guidance. Loads, seals, lubricant condition and driving use influence wear.
An accessible mount or seal differs from internal transmission work. Gearbox identification and diagnosis are essential to a useful quote.
BMW automatics with a torque converter work differently from dual-clutch transmissions.
BMW rear-drive, front-drive and xDrive applications as equipped; layouts differ by platform.
