Transmission Cooling

Transmission Cooling

Inspection and Verification

NOTICE: When internal wear/damage occurs in the transmission, metal particles, clutch plate material and band material can travel into the torque converter, the transmission fluid cooler tubes, the in-tank transmission fluid cooler and the auxiliary transmission fluid cooler, if so equipped. 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.

1. Visually inspect for obvious signs of mechanical damage, incorrect component installation and system leaks. Repair as necessary.
- Install a new or remanufactured radiator when transmission fluid is found leaking from the in-tank transmission fluid cooler.

- Install a new auxiliary transmission fluid cooler if there is leakage from the auxiliary transmission fluid cooler.


2. If the fault is not visually evident, GO to Symptom Chart- Transmission Cooling Symptom Chart - Transmission Cooling or GO to Symptom Chart- NVH Symptom Chart - NVH.
