Automatic Transaxle Disassembly

AUTOMATIC TRANSAXLE DISASSEMBLY

Precaution

General notes
^ The oil pan could contain small chips, shavings, and other particles which may be helpful in checking the condition of the transaxle and diagnosing certain problems. To ensure that all foreign particles stay in the oil pan, make sure that the transaxle is never tipped completely over while the oil pan is still installed.
1) Disassemble the transaxle in a clean area (dustproof work space) to prevent entry of dust into the mechanisms.
2) Inspect the individual transaxle components in accordance with the QUICK DIAGNOSIS CHART during disassembly.
3) Use only plastic hammers when applying force to separate the light alloy case joints.
4) Never use rags during disassembly; they may leave particles that can clog fluid passage.
5) Several parts resemble one another, arrange them so that they do not get mixed up.
6) Disassemble the control valve component and thoroughly clean it when the clutch or brake band has burned or when the ATF has degonerated.

Disassembly procedure
1. Remove the torque converter, and immediately turn it so that the hole faces upward. This will help to keep any remaining fluid from spilling.
2. Pull out the oil pump shaft by hand.
3. Remove the ATF dipstick and oil filler tube.
4. Remove the O-ring from the oil filler tube.
5. Remove the breather hose.
6. Assemble the SST.





7. Attach suitable hangers to the oil pump as shown.





Warning
^ Although the stand has a self-locking brake system, there is a possibility that the brake may not hold when the transaxle is held in a lopsided position on the stand. This would cause the transaxle to turn suddenly, causing serious injury. Never keep the transaxle tilted to one side.
Always hold the rotating handle firmly when turning the transaxle.





8. Lift the transaxle and mount it on the SST.





9. Remove the input/turbine speed sensor, transaxle range switch, and bracket.
10. Remove the O-ring from the input/turbine speed sensor.
11. Remove the vehicle speedometer sensor.
12. Remove the O-ring from the vehicle speedometer sensor.
13. Disconnect the coupler.
14. Remove the connector bolt.
15. Remove the packing, oil pipe, spring, and steel ball.
16. Remove the oil pan and gasket.
Examine any material found in the pan or on the magnet to determine the condition of the transaxle. If large amounts of material are found, replace the torque converter and carefully check the transaxle for the cause.
1) Clutch facing material
^ Drive plate and brake band wear
2) Steel (magnetic)
^ Bearing, gear, and driven plate wear
3) Aluminum (nonmagnetic)
^ Aluminum part wear
17. Disconnect the solenoid valve connector and transaxle fluid temperature sensor.
18. Remove the bolts and brackets shown in the figure.





19. Remove the control valve body.
20. Remove the coupler.
21. Remove the O-ring from the coupler.
22. Remove the oil pump and gasket
23. Remove the clutch component.
1) Remove the turbine shaft snap ring.
2) Pull the reverse forward drum and remove the clutch component.
24. Remove the small sun gear and one-way clutch 1.
25. Remove the 2-4 brake band, and hold it together by using a piece of wire as shown in the figure.





26. Pull out the anchor shaft while holding the strut, then remove the strut.
27. Remove the band servo.
1) Remove the snap ring by using SST and a screwdriver.





2) Remove the band servo and spring.
28. Remove the one-way clutch 2 and carrier hub component.
1) Remove the snap ring.
2) Remove the one-way clutch 2 together with the carrier hub component.
29. Remove the friction plate.
30. Remove the internal gear.
1) Remove the snap ring from the output shell.





2) Remove the internal gear from the output shell.
31. Remove the 3-4 clutch and turbine shaft.
1) Remove the O-ring from the turbine shaft at the converter housing side.
2) Remove the turbine shaft and 3-4 clutch together as an assembly.
3) Separate the turbine shaft and 3-4 clutch.
32. Remove the bolts and remove the transaxle case by tapping lightly with a plastic hammer.
33. Remove the output shell from the output gear.
34. Remove the differential.
35. Remove the bearing housing.
1) Remove the roll pin by using a pin punch.





2) Remove the bearing housing by tapping lightly with a plastic hammer.
36. Remove the idler gear and output gear by tapping it out from the torque converter side.
37. Remove the bearing cover component.
1) Remove the bearing cover bolts.
2) Remove the converter housing from the SST (transaxle hanger).
3) Press the bearing cover out of the converter housing by using a suitable pipe.





38. Press out the bearing race by using the SST
