Transaxle Unit (Disassembly)

SST:

Preparation

Precaution

General Notes:
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 passages.
5. Several parts resemble one another; organize them so that they do not get mixed up.
6. Disassemble the control valve assembly and thoroughly clean it when the clutch or brake band has burned or when the ATF has degenerated.

Cleaning Notes:
1. Clean the transaxle exterior thoroughly with a steam cleaner or cleaning solvents before disassembly.
2. Clean the removed parts with cleaning solvent, and dry with compressed air. Clean out all holes and passages with compressed air, and check that there are no obstructions.
3. Wear eye protection when using compressed air to clean components.













Components

Procedure

NOTE: Do not allow the ATF to spill when removing the torque converter.




1. Remove the torque converter from the converter housing.




2. Pull out the oil pump shaft by hand.




3. Remove the oil level gauge and oil filler tube.




4. Assemble the SST.




5. Attach a suitable hanger to the oil pump as shown.




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






WARNING Do not lean the transaxle to one side during disassembly. It may turn suddenly and cause injury.




7. Remove the pulse generator, inhibitor switch and bracket.




8. Disconnect the solenoid connector.

CAUTION: Remove the oil pan before turning the transaxle over. This will ensure that any foreign material remains in the pan.




9. Remove the oil pan and gasket.
Examine any material found in the pan or on the magnet to determine the condition of the transaxle.

Clutch facing material Drive plate and brake band wear
Steel (magnetic) Bearing, gear, and driven plate wear
Aluminum (nonmagnetic) Bushings or cast aluminum parts wear

If large amounts of material are found, replace the torque converter and carefully check the transaxle for the cause.




10. Remove the clip.
11. Disconnect the solenoid valve connector.




12. Remove bolts A and B and the brackets shown in the figure.

Bolt length (Measured from below the head)
A: 30 mm {1.18 in}
B: 50 mm {1.97 in}

CAUTION: Do not remove the control valve body unless you also remove the oil pipes.




13. Remove the control valve body.




14. Remove the throttle cable.
1. Remove the throttle cable attaching bolt and bracket.
2. Remove the cable from the throttle lever of the valve body.




15. Remove the manual shaft and manual plate.
1. Loosen the nut and pull out the manual shaft.
2. Remove the nut, washer, and manual plate.




16. Remove the bolt and lever holder.




17. Remove the parking assist lever.




18. Remove the detent lever and return spring.
19. Remove the actuator support.

27. Remove the one-way clutch 2 and carrier hub assembly.




1. Remove the snap ring.




2. Remove the one-way clutch 2 together with the carrier hub assembly.

28. Remove the internal gear.




1. Remove the snap ring.




2. Remove the internal gear from the output shell.

29. Remove the 3-4 clutch assembly.




1. Remove the O-ring from the turbine shaft at the converter housing side.




2. Pull out the turbine shaft to remove the 3-4 clutch assembly.
3. Remove the 3-4 clutch assembly.




30. Remove the bolts and remove the transaxle case by tapping lightly with a plastic hammer.




31. Remove the output shell from the output gear.




32. Remove the differential assembly.




33. Remove the bearing housing.
1. Remove the bolt indicated in the figure for access to the roll pin.
2. Remove the roll pin with a pin punch.
3. Remove the bearing housing by tapping lightly with a plastic hammer.




34. Remove the idler gear assembly and output gear assembly by tapping out from the torque converter side.
35. Remove the bearing cover.




1. Remove the bearing cover bolts.
2. Remove the converter housing from the SST (transaxle hanger).




3. Press the bearing cover assembly out of the converter housing.

NOTE: Install the bearing outer race during reassembly to adjust the preload.




36. Press out the bearing outer races by using the SST.
