FLUSHING THE TRANSMISSION FLUID COOLER AND LINE

The fluid cooler and lines may be flushed under the
following condition. This will help prevent more trouble
after the transmission is repaired.

1. When an abnormal amount of debris is found.

2. When an abnormal wear or chips on gears and

shafts is found while overhauling.

3. When there is abnormal clutch facing wear and oil

contamination found.

Procedures

1. Block the wheels.

2. Disconnect the negative battery cable.

3. Raise the vehicle and support it with suitable safety

stands.

4. Disconnect the fluid cooler lines at the transmission

case and fluid cooler.

5. Flush and back-flush the fluid cooler and lines using

solvent and compressed air.

Note:

DO NOT exceed (200 kPa/2.0 kgf/cm

2

/28 psi) air

pressure, or damage may result to oil cooler.

6. Remove all remaining solvent from the system with

compressed air.

7. Flush the cooling system again with Automatic

Transmission Fluid (ATF).

After the final flush, connect all lines.

Cooler line joint connector torque :

44 N·m (4.5 kgf·m/33 lb·ft)

8. Replenish the ATF.

9. Start the engine to test the system for the free flow of

fluid. If the flow is restricted, the cooler assembly or

lines must be replaced.

Repeated cleaning and flushing may not remove all

the debris from the fluid cooler circuit.

Move the select lever through the various ranges and

return to neutral.

Check for fluid level.

If the fluid level is below the specified range, ATF

must be added.
