3. Drain the fluid.
Refer to “ATF CHANGE” in this section.
4. Remove the 19 bolts and oil pan.
5. Inspect the bottom of the oil pan and strainer netting for foreign material (clutch facing and metal
shavings).
If there is an excessive accumulation of foreign material, the oil strainer must be replaced.
Further inspection is required to determine the source of the foreign material.
6. Remove the harness assembly (including the oil temperature sensor).
7. Remove the 11 bolts and the solenoid fixing plate.
8. Remove the 6 solenoids and 3 oil pressure switches.

Inspect
Oil pressure switch
Apply compressed air (390 kPa/4.0 kgf/cm2/57 psi) to
the oil pressure switch to check the oil pressure switch
continuity between the connector and screw.
Replace the oil pressure switch if the result of inspection
is abnormal.

Oil temperature sensor (harness assembly)
Check the oil temperature sensor resistance between
harness terminals 7 and 6 (ground).
Oil temperature sensor resistance:
2,400~2,600 ohms (20 °
°°
°
C)
244L300011

Solenoid
Measure the resistance of each solenoid.
Resistance:
Brown connector – 3.0~3.4 ohms (20 °
°°

Replace the solenoid if the result of inspection is
abnormal.

Install or connect
1. Install the O-rings to each of the solenoids.
2. Install the 6 solenoids and 3 oil pressure switches.
Line pressure solenoid bolt torque:
8 N·m (0.8 kgf·m/69 lb·in)
Oil pressure switch bolt torque:
4 N·m (0.4 kgf·m/35 lb·in)

Bolt torque : 8 N·m (0.8 kgf·m/69 lb·in)
3. Connect the 2 harness connectors.
4. If removed, install the oil strainer.
Refer to “Solenoids, Oil Pressure Switch and Oil Temperature Sensor” previously in this section.
5. Install the new gasket and oil pan.
Bolt torque : 8 N·m (0.8 kgf·m/69 lb·in)

Refer to “ATF CHANGE” in this section.
7. Connect the negative battery cable.
8. Remove the wheel blocks.

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. W hen an abnormal amount of debris is found.
2. W hen an abnormal wear or chips on gears and shafts is found while overhauling.
3. W hen 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 safet
y
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 o
f
fluid. If the flow is restricted, the cooler assembly o
r
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.
10. Connect the negative battery cable.
11. Remove the safety stands.
12. Remove the wheel blocks.
