Transmission Cooler: Initial Inspection and Diagnostic Overview
Transmission Cooling
Transmission Cooling
CAUTION: Whenever a transmission has been disassembled to install new parts, a new transmission fluid cooler must be installed and the
transmission fluid cooler tubes must be cleaned and backflushed.
NOTE: Cleaning and backflushing the transmission fluid cooling system (along with normal cleaning and inspection procedures, as outlined during
disassembly and assembly) will keep contamination from reentering the transmission and causing a repeat repair.
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 transmission fluid cooler. These contaminants are a major cause of recurring transmission troubles and must be removed from the
system before the transmission is put back in use.
Inspection and Verification
Inspection and Verification
When transmission fluid leakage is found in the transmission fluid cooler, install a new transmission fluid cooler.
When there is evidence of transmission assembly or transmission fluid contamination due to the following transmission failure modes, install a new
transmission fluid cooler.
^
Major metallic failure
^
Multiple clutches or clutch plate failure
^
Sufficient component wear which results in metallic contamination
If the fault is not visually evident, GO to Symptom Chart - Transmission Cooling or GO to Symptom Chart - Noise, Vibration and Harshness (NVH).
