WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2003 GMC Sierra, 2003 GMC Cab & Chassis Sierra, 2003 Chevrolet Silverado, 2003 Chevrolet Cab & Chassis Silverado, and 2002 GMC Sierra. However, it is still accessible from the selected car via links, so may be relevant.

Several torque converters are available to match the transmissions to a wide variety of diesel and gasoline engines. The torque converter is a single-stage, polyphase, 3-element unit. It consists of a pump, stator, and turbine.

At lower output speeds, the torque converter multiplies torque and provides a fluid coupling to the engine. At higher speeds, the Torque Converter Clutch (TCC) is automatically engaged to provide direct drive from the engine to the transmission. Hydraulic fluid for converter charging pressure comes from the sump and is supplied by the input pump.

The TCC is applied or released by changing direction of fluid in the torque converter. An integral converter damper minimizes the need for additional engine vibration control.
