Torque Converter: Description: Notes
WARNING: This page is about a different car, the 2004 Dodge Dakota. However, it is still accessible from the selected car via links, so may be relevant.
The torque converter ( Fig 1) is a hydraulic device that couples 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.
