Backflushing and Cleaning

1. When internal wear or damage has occurred in the transmission, metal particles, clutch plate material or band material may have been carried into the torque converter and OTA fluid cooler. These contaminants are a major cause of recuffing transmission concerns and must be removed from the system before the transmission is but back into service. The OTA fluid cooler is not serviceable with existing equipment due to the thermostatic bypass valve.
2. The OTA fluid cooler must be replaced under the following conditions:
^ major metallic failure.
^ multiple clutches or clutch plate failure.
^ sufficient component wear that results in metallic contamination.
