Remove or Disconnect
1. Block the wheels.
2. Disconnect the negative battery cable.
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 oil
temperature sensor).
7. Remove the 11 bolts and the solenoid fixing plate.
8. Remove the 6 solenoids and 3 oil pressure switchs.

Inspect
Oil pressure switch
Apply compressed air (392 kPa/4.0 kg/cm2) to the oil
pressure switch to check the oil pressure switch
continuity between the connector and screw.

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




C)
Gray connector – 12.0~13.2 ohms (20




C)
White connector – 12.2~13.4 ohms (20




C)
Install or connect
1. Install the O-rings to each of the solenoids.
2. Install the 6 solenoids and 3 oil pressure switchs.
Line pressure solenoid bolt torque:
8 N·m (69 lb·in)
Oil pressure switch bolt torque:
4.4 N·m (39 lb·in)
3. Install the solenoid fixing plate together with the
harness brackets.

6. Fill the fluid.
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. When the abnormal amount of debris are found.
2. When the abnormal wear or chips on gears and
shafts are found while overhauling.
3. When the abnormal clutch facing wear and oil
contamination are found.

Procedures
1. Block the wheels.
2. Disconnect negative battery cable.
3. Raise vehicle and support with suitable safety
stands.
4. Disconnect fluid cooler lines at transmission case
and fluid cooler.
5. Flush and back-flush the fluid cooler and lines using
solvent and compressed air.
Note:
DO NOT exceed 197 kPa (29 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 (33 lb·ft)
8. Replenish ATF
9. Start 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
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 negative battery cable.
11. Remove safety stands.
12. Remove wheel blocks.
