CONVERTER-TORQUE
DESCRIPTION
The torque converter is a hydraulic device that cou-
ples the engine crankshaft to the transmission. The
torque converter consists of an outer shell with an
internal turbine, a stator, an overrunning clutch, an
impeller and an electronically applied converter clutch.
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.
