Oil Cooler

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 oil 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, the torque converter and transmission oil cooler must be cleaned by using a mechanically agitated cleaner, such as Rotunda Torque Converter and Oil Cooler Cleaner 014-00028 or equivalent.

The lack of a drain plug in the torque converter increases the amount of residual flushing solvent retained in the torque converter after cleaning. This retained solvent is not acceptable and a method of diluting it is required. The following procedure is to be used after removal of the torque converter from the cleaning equipment.

1. Thoroughly drain remaining solvent through hub.

2. Add 1.9 liter (2.0 qt) of clean transmission fluid to torque converter . Agitate by hand.

3. Thoroughly drain solution through torque converter hub.
