Transmission Cooler: Initial Inspection and Diagnostic Overview
Inspection and Verification
CAUTION: 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. Refer to transmission fluid cooler flow testing,
backflushing and cleaning, torque converter cleaning and inspection and flushing.
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 intank 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. See: Symptom Related Diagnostic Procedures/Symptom Chart - Transmission Cooling
