Transmission Cooler: Procedures
Transmission Fluid Cooler Backflushing and Cleaning - Manual Transmission
Transmission Fluid Cooler Backflushing and Cleaning - Manual Transmission
NOTICE: When internal wear or damage occurs in the transmission, component material can travel into the transmission 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 transmission fluid cooler inlet tube to aid in connecting it to the torque converter and fluid
cooler cleaner.
Connect the in-tank transmission 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 transmission fluid cooler return tube to aid in connecting it to the torque converter and fluid
cooler cleaner.
Connect the in-tank transmission 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 transmission fluid cooler inlet tube and return tube.
7. Fill with full synthetic manual transmission fluid and check for leaks.
Transmission Fluid Cooler Flow Test - Manual Transmission
Transmission Fluid Cooler Flow Test - Manual Transmission
1. With the vehicle in NEUTRAL, position on a hoist.
2. Disconnect the in-tank transmission fluid cooler return tube (top fitting) from the transmission.
3. Connect one end of a 9.25 mm (0.364 in) inner diameter x 1,500 mm (59.055 in) long hose to the in-tank transmission fluid cooler return tube and
insert the other end into the transmission fluid fill hole in the transmission case.
4. Start the engine and run it at idle with the transmission in NEUTRAL.
5. NOTE: The transmission fluid flow must be steady (without air bubbles) to make sure of an accurate reading.
Remove the end of the hose from the transmission fluid fill hole in the transmission case and place it into a measuring container for 15 seconds.
After 15 seconds, insert the end of the hose back into the transmission fluid fill hole in the transmission case.
