Flushing Procedure

TORQUE CONVERTER FLUSHING
^ When internal wear or damage has occurred in the transaxle, metal particles, clutch plate material, or band material may have been carried into the converter and fluid cooler. These contaminants are a major cause of recurring transaxle troubles and MUST be removed from the system before the transaxle is put back into service.

^ Whenever a transaxle has been disassembled to replace worn or damaged parts or because the main control valve body sticks due to foreign material, the torque converter and transmission fluid cooler MUST be cleaned by using a mechanically agitated cleaner, such as Rotunda Torque Converter/Oil Cooler Cleaner 014-00028 or equivalent.

NOTE:The lack of a drain plug in the AX4S 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 AX4S torque converter from the cleaning equipment:

1. Thoroughly drain remaining solvent through hub.
2. Add 2.0 quarts (1.9 liters) of clean transmission fluid to converter. Agitate by hand.
3. Thoroughly drain solution through converter hub.
