- Check equipment for wear and cracks before using. Replace any worn or cracked components.
- 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.
- Secure the flusher filler cap, and pressurize the flusher with compressed air to 550-429 kPa (5.6-8.45 kgf/cm 2 , 80 - 120 psi). The air line should be equipped with a water trap to ensure a dray air system.
- Hang the flusher under the vehicle.
- Attach the flusher discharge hose (B) to the return line of the ATF cooler using a clamp.
- 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.
- With the water and air valves (A) off, attach the water and air supplies to the flusher. (Hot water if available.)
- Turn on the water valve for 10 seconds. If water does not flow through the cooler, it is completely plugged, it cannot be flushed, and must be replaced.
- Depress the trigger to mix the flushing fluid into the water flow. Use the wire clip to h old the trigger down.
- While flushing with the water and flushing fluid for 2 minutes, turn the air valve on for 5 seconds every 15 - 20 seconds to create a surging action. Air Pressure: MAX 845 kPa (8.45 kgf/cm 2 , 120 psi)
- Turn the water valve off. Release the trigger, then reverse the hoses to the cooler so you can flush in the opposite direction. Repeat steps 8 through 10 .
- Release the trigger, and rinse the cooler with water for 1 minute.
- Turn the water valve off and the water supply off.
- Turn the air valve on for 2 minutes, or until no moisture is visible leaving the drain hose. Residual moisture in the cooler or lines can damage the transmission.
- Remove the flusher from the cooler line. Attach the drain hose to an ATF container.
- Install the transmission, and leave the drain hose attached to the cooler line.
- Make sure the transmission is in the P position. Fill the transmission with ATF, and run the engine for 30 seconds or until approximately 0.95 l (1.0 US qt) is discharged.
- Remove the drain hose, and reconnect the cooler return hose to the transmission.
- Refill the transmission with ATF to the proper level (see «ATF Replacement»(ref-171202-S34250251042005013100000) ).
Scheme 396
- Slide the ATF cooler hoses (A) on the ATF filter (B) until they are 5 - 6 mm (0.20-0.24 in.) (C) away from the filter housing.
- Secure the hoses with the clips (D) at 10 - 12 mm (0.4-0.5 in.) (E) from the filter housing.
- Slide the ATF cooler hoses (F) over the ATF cooler lines (G), then secure the hoses with the clips (H) at 2-4 mm (0.1-0.2 in.) (l) from the hose ends.
- Install the hoes clamp (J) at the marks (K) on the ATF cooler hoses.
