Transmission Cooler: Flow of Diagnosis
Inspection and Verification (Start Testing Here)
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 the auxiliary transmission fluid cooler. These contaminants are a major cause of recurring transmission concerns and must be
removed from the system before the transmission is put back into service.
When fluid leakage is found at any of the transmission fluid cooling components, a new component must be installed.
