Transmission Fluid Cooler Backflushing and Cleaning - Manual Transmission

CAUTION: When internal wear or damage occurs in the transmission, component material can travel into the fluid cooler tubes and the in-tank transmission fluid cooler. Cleaning and backflushing the transmission fluid cooling system and following all of the normal cleaning and inspection procedures during transmission disassembly and assembly will keep contamination from re-entering the transmission and causing a repeat repair. Clean and backflush the in-tank transmission fluid cooler and the transmission fluid cooler tubes with a suitable torque converter and fluid cooler cleaner every time the transmission is exchanged or overhauled.

1. NOTE: Attach a rubber hose to the end of the in-tank fluid cooler inlet tube to aid in connecting it to the torque converter and fluid cooler cleaner.

Connect the in-tank fluid cooler inlet tube to the torque converter and fluid cooler cleaner pressure line.

2. NOTE: Attach a rubber hose to the end of the in-tank fluid cooler return tube to aid in connecting it to the torque converter and fluid cooler cleaner.

Connect the in-tank fluid cooler return tube to the torque converter and fluid cooler cleaner return tube.
3. Place the other end of the torque converter and fluid cooler cleaner return line in the solvent tank reservoir.

4. NOTE: Cycling the solvent pump on and off will help dislodge contaminants in the cooling system.

Switch the solvent pump on. Allow the solvent to circulate a minimum of 5 minutes.
5. Switch the solvent pump off.
6. Disconnect the in-tank ends of the in-tank fluid cooler inlet tube and return tube.
