Transaxle Cooling

TRANSAXLE COOLING

Caution
^ Whenever the transaxle has been disassembled to install new parts, the transaxle fluid cooler and the fluid cooler tubes should be flushed. Failure to clean the transaxle fluid cooler or the cooler tubes will cause transaxle failure.

Note
^ Some vehicles are equipped with a cold weather cooler bypass valve (CBV). This valve cannot be flushed. Install a new CBV as part of an overhaul or installation of a remanufactured transaxle.

Note
^ Cleaning and backflushing the transaxle fluid cooling system as outlined will keep contamination from reentering the transaxle and causing a repeat repair.

When internal wear or damage has occurred in the transaxle, metal particles or clutch plate material may have been carried into the torque converter and transaxle fluid cooler. These contaminants are a major cause of recurring transaxle concerns and must be removed from the system before the transaxle is put back in use.
