Transmission Cooler: Initial Inspection and Diagnostic Overview
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. Refer to Cooling
System &/or Engine Block Heater.
-
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 or GO to Symptom Chart - NVH. See: Symptom Related
Diagnostic Procedures/Symptom Chart - Transmission Cooling See: Symptom Related Diagnostic Procedures/Symptom Chart - NVH
