Transmission Fluid Cooler

NOTICE: If the transmission was disassembled to install new parts, backflush and clean the transmission fluid cooler and transmission fluid cooler tubes.

NOTE: Backflushing and cleaning the transmission fluid cooling system, along with following all the normal cleaning and inspection procedures during disassembly and reassembly, keeps contaminants from entering the transmission, causing a repeat repair.

If internal wear or damage occurred in the transmission, metal particles or clutch plate 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. For backflushing and cleaning procedures, refer to Transmission Fluid Cooler Backflushing and Cleaning in this section.
