Commercially Available Transmission Cooler Flusher

This procedure should be performed before reinstalling
the transmission.
1. Check equipment for wear and cracks before using.
Replace any worn or cracked components.
2. Using the measuring cup, fill the flusher (A) with 21
ounces (approximately 2/3 full) of biodegradable
flushing fluid (J35944-20). Do not substitute with
any other fluid. Follow the handling procedure on
the fluid container.
3. Secure the flusher filler cap, and pressurize the
flusher with compressed air to 550 829 kPa (5.6
8.45 kgf/cm , 80 120 psi). The air line should be
equipped with a water trap to ensure a dry air
system.
4. Hang the flusher under the vehicle.
5. Attach the flusher discharge hose (B) to the return
line of the ATF cooler using a clamp.
6. Connect the drain hose (C) to the inlet line on the
ATF cooler using a clamp. Securely clamp the
opposite end of the drain hose to a bucket (D) or
floor drain.
7. With the water and air valves (A) off, attach the
water and air supplies to the flusher. (Hot water if
available.)
8. Turn on the water valve for 10 seconds. If water
does not flow through the cooler, it is completely
plugged, cannot be flushed, and must be replaced.
9. Press the trigger to mix the flushing fluid into the
water flow. Use the wire clip to hold the trigger
down.
10. While flushing with the water and flushing fluid for
two minutes, turn the air valve on for five seconds
every 15
20 seconds to create a surging action.
11. Turn the water valve off. Release the trigger, then
reverse the hoses to the cooler so you can flush in
the opposite direction. Repeat step 8 through 10.
12. Release the trigger, and rinse the cooler with water
for one minute.
13. Turn the water valve and the water supply off.
14. Turn the air valve on for two minutes, or until no
moisture is visible leaving the drain hose. Residual
moisture in the cooler or lines can damage the
transmission.
15. Remove the flusher from the cooler line. Attach the
drain hose to an ATF container.
16. Install the transmission, and leave the drain hose
attached to the cooler line.
