Transmission Fluid Cooler Backflushing and Cleaning

Transmission Fluid Cooler Backflushing and Cleaning

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

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