Torque Converter: Description and Operation

The torque converter is similar in function and design to other Chrysler torque converters. The torque converter clutch engages or disengages the turbine assembly to the impeller housing. The application of the converter clutch is controlled electronically by the solenoid assembly and valve body. The torque converter transmits torque from the engine crankshaft to the input shaft of the transaxle.

The torque converter clutch may engage (under the right conditions) in either 2nd, 3rd or 4th gears. The torque converter clutch engagement is normally very smooth and may even be undetectable by the driver. There are two types of torque converter engagement: partial and full engagement.
