DESCRIPTION
Figure 1 Torque Converter Assembly
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) (Figure 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.
