Transmission Fluid Cooler Backflushing and Cleaning

Transmission Fluid Cooler Backflushing and Cleaning

1. With the vehicle in NEUTRAL, position it on a hoist. For additional information, refer to Vehicle Jacking and Lifting.

2. 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 fluid 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. For additional information, refer to Transmission Fluid Cooler Transmission Fluid Cooler. For transmission fluid cooler tube backflushing and cleaning, refer to Automatic Transmission/Transaxle &/or Transmission Control Systems.
