CHRYSLER – 42RE TECHTRAN MANUAL – ATSG (Automatic Transmission Service Group)

A three element torque converter is used for all applications in the 42RE. Torque converter elements consist of the turbine, stator and impeller. The converter also contains an overrunning clutch and a converter clutch plate.

The converter clutch is electronically controlled. The converter clutch provides reduced engine RPM and greater fuel economy when it is engaged. Converter clutch engagement also provides much reduced transmission fluid temperatures.

The converter clutch will engage in 4th gear, and in 3rd gear when the overdrive control switch is in the OFF position.

The overrunning clutch is mounted in the stator hub, and prevents the stator from rotating in a direction opposite to the engine rotation. This retains the torque multiplication feature of the converter.

The torque converter should be replaced as an assembly when diagnosis indicates a malfunction has occured.
