Transmission Fluid Cooler

NOTICE: Whenever a transmission has been disassembled to install new parts, the transmission fluid cooler tubes and the in-tank fluid cooler, if equipped, must be backflushed and cleaned. Refer to Transmission Fluid Cooler Backflushing and Cleaning Transmission Fluid Cooler Backflushing and Cleaning.

NOTE: If the vehicle is equipped with an auxiliary transmission fluid cooler, a new auxiliary transmission fluid cooler must be installed.

NOTE: Cleaning and backflushing the transmission fluid cooling system along with following all the normal cleaning and inspection procedures during disassembly and reassembly 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 issues and must be removed from the system before the transmission is put back into use.

Prior to installing the transmission, the transmission in-tank fluid cooler, transmission fluid cooler tubes and transmission fluid cooler hoses need to be backflushed and cleaned. Refer to Transmission Fluid Cooler Backflushing and Cleaning Transmission Fluid Cooler Backflushing and Cleaning.
