- The old conical spring washer and the old locknut.
- Areas where the park gear contacts the conical spring washer.

7. Install the park gear (J), the old conical spring washer (K), and the old locknut (L) on the countershaft (M).

8. Lift the park pawl up, and engage it with the park gear, then tighten the locknut to 226 Nm (23.0 kg-m,166 lb-ft).

NOTE:

- Do not tap the park gear to install.
- Use a torque wrench to tighten the locknut. Do not use an impact wrench.
- Countershaft locknut has left-hand threads.

9. Remove the locknuts and the conical spring washers from the mainshaft and the countershaft.

10. Lubricate the threads of the shafts, new locknuts, and new conical spring washers with ATF.

11. Install new conical spring washers (A) with the stamped mark side facing up in the direction shown, and install a new mainshaft locknut (B), a new countershaft locknut (C), and a new secondary shaft locknut (D).





12. Tighten the locknuts to 167 Nm (17.0 kg-m, 123 lb-ft).

NOTE:

- Be sure to install the conical spring washers in the direction shown.
- Use a torque wrench to tighten the locknut. Do not use an impact wrench.
- Countershaft and secondary shaft locknuts have left-hand threads.

13. Remove the mainshaft holder from the mainshaft.

14. Stake the locknuts into the shafts in depth (A) of 0.7-1.3 mm (0.03-0.05 in) using a 3.5 mm punch (B).






15. Install the selector control level (A) on the selector control shaft (B), and install the bolt with a new lock washer (C), then bend the lock tab of the lock washer against the bolt head.






16. Set the park lever in the P position, then check that the park pawl (A) engages the park gear (B).





17. If the park pawl does not engage fully, do the park lever stop inspection and adjustment Transmission End Cover Park Lever Stop Inspection And Adjustment.

18. Tighten the lock bolt (C), and bend the lock tab of the lock washer (D) against the bolt head.

19. Install the ATF feed pipe (A) into the idler gear shaft, and install the ATF lubrication pipe (B) into the transmission housing.






20. Install a new gasket (A) on the transmission housing, and install the two dowel pins (B) and new O-rings (C) over the top of the ATF feed pipes.





21. Install the end cover (D), and tighten the three special bolts (E) and the 6 x 1.0 mm bolts (12 bolts).

22. Install the harness clamp bracket (F) on the end cover.

23. Move the selector control shaft (A) from the P position to the N position by turning the selector control shaft on the torque converter side.

NOTE: Do not squeeze the end of the selector control shaft tips together when turning the shaft. If the tips are squeezed together it will cause a faulty shift position signal or position due to the play between the selector control shaft and the transmission range switch.






24. Align the cutouts (A) on the control shaft with the neutral positioning cutouts (B) on the transmission range switch (C), then put a 2.0 mm (0.08 in) feeler gauge blade (D) in the cutouts to hold in the N position.

NOTE: Be sure to use a 2.0 mm (0.08 in) blade or equivalent to hold the transmission range switch in the N position.






25. Install the transmission range switch (A) gently on the selector control shaft (B) while holding it in the N position with the 2.0 mm (0.08 in) blade (C).






26. Tighten the bolts on the transmission range switch while you continue to hold it in the N position. Do not move the transmission range switch when tightening the bolts. Remove the feeler gauge.






27. Connect the transmission range switch connector (A) securely, then install the harness clamps (B) on the clamp bracket (C).





28. Install the transmission range switch cover (D).

29. Clean the mounting surface and the fluid passage of A/T clutch pressure control solenoid valve A and the transmission housing.

30. Install a new gasket (B) on the transmission housing, and install the ATF pipe (C) and the ATF joint pipes (D).
