Part 1

Disassembly

1. Drain ATF through drain hole.
2. Remove drain plug gasket from drain plug.

4. Check torque converter one-way clutch using check tool as shown in the figure.
a. Insert check tool into groove of bearing support built into one way clutch outer race.
b. When fixing bearing support with check tool, rotate one-way clutch spline using screwdriver.
c. Check that inner race rotates clockwise only. If not, replace torque converter assembly.

5. Remove turbine revolution sensor (power train revolution sensor) (1) from transaxle case (2).
<---: Bolt (1)
6. Remove O-ring (3) from turbine revolution sensor (power train revolution sensor) (1).

7. Remove revolution sensor (1) from transaxle case (2).
<---: Bolt (2)
8. Remove plug or speedometer pinion according to the following procedures.

a. With ABS
i. Remove plug (1) from converter housing (2).
<---: Bolt (1)
ii. Remove O-ring (3) from plug (1).

b. Without ABS
i. Remove speedometer pinion (1) from converter housing (2).
<---: Bolt (1)
i. Remove O-ring (3) from speedometer pinion (1).

9. Set manual shaft (1) in "P" position.
10. Remove PNP switch (2) from transaxle case.
<---: Bolt (3)
11. Remove oil pan fitting bolts.
12. Remove oil pan and oil pan gasket.

13. Check foreign materials in oil pan to help determine causes of malfunction. If the ATF is very dark, smells burned, or contains foreign particles, frictional material (clutches, band) may need replacement. A tacky film that will not wipe clean indicates varnish build up. Varnish can cause valves, servo, and clutches to stick and can inhibit pump pressure.
If frictional material is detected, replace radiator after repair of A/T.
14. Remove magnets from oil pan.
15. Remove control valve assembly according to the following procedures.

a. Remove snap ring (1) from terminal body (2).

CAUTION: Do not expand snap ring (1) excessively.

b. Push terminal body (2) into transaxle case.
c. Remove control valve assembly fitting bolts A, B and C.

d. Remove control valve assembly from transaxle case.

CAUTION: Be careful not to drop manual valve.

16. Remove manual valve from control valve assembly.
^ Inspect the sliding surfaces of manual valve and valve body, and replace if damaged or dented.

CAUTION: Be careful not to drop manual valve.

17. Remove O-ring from terminal body.

18. Remove return spring from servo release accumulator piston.

19. Apply compressed air into the oil hole as shown in the figure, and remove servo release accumulator piston from transaxle case.

CAUTION: Strong flow of air will push the accumulator piston out along with a splash of ATE Cover the area with lint-free cloth and blow air little by little to avoid this.

20. Apply compressed air into the oil hole as shown in the figure, and remove N-D accumulator piston and return spring from transaxle case.

CAUTION: Strong flow of air will push the accumulator piston out along with a splash of ATF Cover the area with lint free cloth and blow air little by little to avoid this.

21. Remove O-rings (1) from servo release accumulator piston (2) and N-D accumulator piston (3).

CAUTION: Wrap the removed servo release accumulator piston (2) and N-D accumulator piston (3) in a lint-free cloth.

^ Inspect the sliding surfaces of each accumulator piston and transaxle case, and replace if damaged or dented.
(1): Servo release accumulator piston
(2): N-D accumulator piston

^ Inspect each return spring, and replace if deformed or worn. Refer to AT-343, "Accumulator" for free length (L1) and length (L2). Accumulator
(1): Return spring (Servo release accumulator)
(2): Return spring (N-D accumulator)

CAUTION: Do not remove spring retainer (3).

22. Remove lip seals (1) from transaxle case.
23. Remove converter housing according to the following procedures.

a. Remove converter housing fitting bolts (1) and (2) using a power tool.
b. Remove bracket from converter housing
c. Remove converter housing by tapping it lightly.

d. Remove O-ring from differential lubricant hole.

24. Remove final drive assembly from transaxle case.

25. Remove differential side bearing outer race from transaxle case and converter housing.

26. Remove differential side bearing adjusting shim from transaxle case.

27. Remove RH differential side oil seal from converter housing using a flat-bladed screwdriver.

CAUTION: Be careful not to scratch converter housing.

28. Remove differential lubricant tube (1) and clips (2) from converter housing.
<---: Bolt (3)
29. Remove oil pump assembly according to the following procedures

a. Remove O-ring from input shaft assembly (high clutch drum).

b. Remove oil pump assembly fitting bolts, and then remove oil pump assembly (1) from transaxle case.
c. Remove O-ring from oil pump assembly (1).

d. Remove bearing race (1) and thrust washer (2) from oil pump assembly (3).
