Disassembly


CAUTION:
Never disassemble parts behind Drum Support. Refer to Cross-Sectional View, Cross-Sectional View, Cross-Sectional View.
1. Drain ATF through drain plug.





2. Remove torque converter by holding it firmly and turning while pulling straight out.





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





4. Remove tightening bolts (1) for converter housing and transmission case.
5. Remove converter housing from transmission case.

CAUTION:
Be careful not to scratch converter housing.





6. Remove O-ring from input clutch assembly.





7. Remove tightening bolts for oil pump assembly and transmission case.





8. Attach the sliding hammers to oil pump assembly and extract it evenly from transmission case.

CAUTION:
- Fully tighten the sliding hammer screws.
- Make sure that bearing race is installed to the oil pump assembly edge surface.





9. Remove O-ring from oil pump assembly.





10. Remove bearing race from oil pump assembly.





11. Remove needle bearing from front sun gear.





12. Remove front sun gear assembly from front carrier assembly.
NOTE:
Remove front sun gear by rotating left/right.





13. Remove seal rings from input clutch assembly.





14. Remove front carrier assembly from rear carrier assembly. (With input clutch assembly and rear internal gear.)

CAUTION:
Be careful to remove it with needle bearing.





15. Loosen lock nut and remove band servo anchor end pin from transmission case.





16. Remove brake band from transmission case.





- To prevent brake linings from cracking or peeling, never stretch the flexible band unnecessarily. When removing the brake band, always secure it with a clip as shown in the figure at right.
Leave the clip in position after removing the brake band.
- Check brake band facing for damage, cracks, wear or burns.





17. Remove mid carrier assembly and rear carrier assembly as a unit.





18. Remove mid carrier assembly from rear carrier assembly.





19. Remove needle bearing (front side) from mid carrier assembly.





20. Remove needle bearing (rear side) from mid carrier assembly.





21. Remove bearing race from rear carrier assembly.





22. Remove needle bearing from rear carrier assembly.





23. Remove mid sun gear assembly, rear sun gear assembly and high and low reverse clutch hub as a unit.
CAUTION:
Be careful to remove then with bearing race and needle bearing.





24. Remove high and low reverse clutch assembly from direct clutch assembly.
CAUTION:
Make sure that needle bearing is installed to the high and low reverse clutch assembly edge surface.





25. Remove direct clutch assembly from reverse brake.





26. Remove needle bearing from drum support.





27. Remove snap ring from A/T assembly harness connector.





28. Push A/T assembly harness connector.
CAUTION:
Be careful not to damage connector.

29. Remove oil pan according to the following procedures.
a. VQ35HR models





i. Remove overflow plug (1).
ii. Remove clips (2).
iii. Remove oil pan (3) and oil pan gasket.
b. VK45DE models





i. Remove clips (1) and brackets (2).
ii. Remove oil pan (3) and oil pan gasket.





30. Check foreign materials in oil pan to help determine causes of malfunction. If the ATF is very dark, smells burned, or contains foreign particles, the 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, perform A/T fluid cooler cleaning. Refer to 5AT RE5R05A (VQ35HR) or 5AT RE5R05A (VK45DE).





31. Remove magnets from oil pan.





32. Disconnect A/T fluid temperature sensor 2 connector (A).
CAUTION:
Be careful not to damage connector.
33. Straighten terminal clips ( ) to free terminal cord assembly and A/T fluid temperature sensor 2 harness.





34. Disconnect output speed sensor connector (1).
CAUTION:
Be careful not to damage connector.
