Transmission Fluid Cooler - Backflushing and Cleaning

Transmission Fluid Cooler - Backflushing and Cleaning

1. CAUTION: When internal wear/damage occurs in the transmission, metal particles/clutch plate material/band material can travel into the torque converter and the oil-to-air (OTA) fluid cooler. These contaminants are a major cause of recurring transmission concerns. To prevent future concerns, remove these contaminants from the cooling system before placing the transmission back into use.

Install a new OTA fluid cooler if there is leakage from the OTA fluid cooler, major metallic failure, multiple clutch or clutch plate failure, or sufficient component wear that results in metallic contamination.





2. NOTE: If the vehicle was not equipped with a fluid filter, install a fluid filter service kit. Follow the instructions supplied in the kit. If the vehicle was equipped with a fluid filter, install a new fluid filter.

Install a new inline transmission fluid filter kit or filter and check for leaks.
