Transmission Cooler: Service and Repair
TRANSMISSION OIL COOLER REVERSE FLUSHING/CLEANING
TRANSMISSION OIL COOLER REVERSE FLUSHING DESCRIPTION
Reverse flushing of the transmission oil cooling system is the forcing of fluid (ATF+4) in the opposite direction of normal fluid flow through the cooling system. It is necessary to perform this procedure anytime the transmission is serviced to avoid possible contamination of the cooling system. DO NOT PERFORM THIS PROCEDURE ON ANY VEHICLE THAT DOES NOT USE MOPAR(R) ATF+4 TRANSMISSION FLUID.
