Torque Converter - Description
DESCRIPTION
The torque converter is a hydraulic device that couples the engine crankshaft to the transmission. The torque converter consists of an outer shell with an
internal turbine (1), a stator (4), an overrunning clutch, an impeller (2) and an electronically applied converter clutch (6). The converter clutch provides
reduced engine speed and greater fuel economy when engaged. Clutch engagement also provides reduced transmission fluid temperatures. The torque
converter hub drives the transmission oil (fluid) pump.
The torque converter is a sealed, welded unit that is not repairable and is serviced as an assembly.
CAUTION: The torque converter must be replaced if a transmission failure resulted in large amounts of metal or fiber contamination in the
fluid.
