Transmission Cooler: Initial Inspection and Diagnostic Overview
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 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
When fluid leakage is found in the fluid cooler, install a new fluid cooler. When there is evidence of transmission assembly or fluid contamination due
to the following transmission failure modes, install a new fluid cooler.
^
Major metallic failure
^
Multiple clutches or clutch plate failure
^
Sufficient component wear which results in metallic contamination
