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 over-running clutch, an impeller (2) and an electronically applied converter clutch (5). The converter clutch provides
reduced engine speed and greater fuel economy when engaged. Clutch engagement also provides reduced transmission fluid temperatures. The converter
clutch engages in third gear. The torque converter hub (3) drives the transmission oil (fluid) pump.
The torque converter is a sealed, welded unit that is not repairable and is serviced as an assembly.
