Torque Converter

When internal wear or damage has occurred in the transmission, metal particles, clutch plate material, or band material may have been carried into the torque converter (7902) and transmission fluid cooler (7A095). These contaminants are a major cause of recurring transmission troubles and MUST be removed from the system before the transmission is put back into service.

Whenever a transmission has been disassembled to replace worn or damaged parts or because the valve body valves stick repeatedly from foreign material, the torque converter, transmission fluid cooler and transmission fluid cooler tubes and hoses MUST be cleaned by using a mechanically agitated cleaner, such as Rotunda Torque Converter/Oil Cooler Cleaner 014-00028 or equivalent.

NOTE: Mineral spirits used to clean the torque converter must be fresh, non-chlorinated and non-halogenated.

Flush the torque converter of the remaining solvent using this procedure.

1. Thoroughly drain remaining solvent through the drain plug.

2. Add 1.9L (2.0 U.S. quarts) of clean transmission fluid to the converter. Agitate by hand.

3. Thoroughly drain solution through the drain plug.
