Transmission Fluid Cooler Backflushing and Cleaning

Transmission Fluid Cooler Backflushing and Cleaning

1. With the vehicle in NEUTRAL, position it on a hoist.

2. CAUTION: When internal wear/damage occurs in the transmission, metal particles, clutch plate material and 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 oil-to-air (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.
