Reverse Idler Gear Removal and Installation
Removal
1. Remove the bolt (A) securing the reverse idler gear shaft holder (B).
2. Install a 5 x 0.8 mm bolt (C) in the reverse idler gear shaft (D), and pull it to remove the reverse idler gear shaft and the reverse idler gear shaft holder together.
3. Remove the reverse idler gear.
Installation
1. Install the reverse idler gear in the transmission housing.
2. Lightly coat the reverse idler gear shaft (A), needle bearing (B), and new O-rings (C) with lithium grease.
3. Assemble new O-rings and the needle bearing on the reverse idler gear shaft, then install the reverse idler gear shaft in the reverse idler gear shaft holder (D). Align the D-shaped cut out (E) of the reverse idler gear shaft with the D-shaped area (F) of the reverse idler gear shaft holder.
4. Install the reverse idler gear shaft/holder assembly on the transmission housing.
Shaft Assembly and Housing Installation
A/T Shaft Assembly And Housing:
NOTE: Refer to the Exploded View as needed during the following procedure.
1. Install the differential assembly in the torque converter housing.
2. Install the baffle plate on the servo body.
3. Assemble the mainshaft, the countershaft, and the secondary shaft.
4. Join the mainshaft subassembly (A), the countershaft subassembly (B), and the secondary shaft subassembly (C) together. Then install them in the torque converter housing. Do not bump the countershaft on the baffle plate (D).
5. Make sure the countershaft subassembly and the differential assembly are clear of the baffle plate (D).
6. If the detent arm was removed, install the detent arm (A) with the arm collar (B) on the servo body (C), and Install a new lock washer (D) by aligning its cutout (E) with the projection (F) of the servo body. Install and tighten the bolt, then bend the lock tab of the lock washer against the bolt head.
7. Install the selector control shaft (A) in the torque converter housing aligning the manual valve ]ever pin (B) on the selector control shaft with the guide of the manual valve (C). Pull the manual valve gently when aligning the manual valve with the selector control shaft.
8. Hook the detent spring (A) to the detent arm (B).
9. Turn the shift fork shaft (A) so the large chamfered hole (B) is facing the fork bolt hole (C) of the shift fork (D).
10. Install the shift fork and the reverse selector together on the shift fork shaft and the countershaft subassembly. Secure the shift fork to the shift fork shaft with the lock bolt and a new lock washer (E), then bend the lock tab of the lock washer against the bolt head.
11. Install the needle bearing and the countershaft reverse gear on the countershaft subassembly.
12. Install the reverse idler gear in the transmission housing.
13. Install the idler gear shaft/idler gear assembly, if it was removed.
14. Install the three dowel pins (A) and a new gasket (B) on the torque converter housing (C).
15. Align the spring pin of the selector control shaft (D) with the transmission housing groove (E) by turning the selector control shaft. Do not squeeze the end of the selector control shaft tips together when turning the selector control 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.
16. Place the transmission housing (F) on the torque converter housing. Do not install the mainshaft and countershaft speed sensors before installing the transmission housing on the torque converter housing.
17. Wrap a screwdriver tip with tape to prevent damage to the reverse idler gear teeth. Engage the reverse idler gear with reverse gears by rotating the idler gear using the screwdriver.
18. Install the transmission housing mounting bolts, and tighten the 19 bolts to 44 N-m (4.5 kgf-m, 33 lbf-ft) in at least two steps, in a crisscross pattern.
19. Install a new O-ring (A) on the input shaft (mainshaft) speed sensor (B), and install the input shaft (mainshaft) speed sensor in the transmission housing.
20. Install a new O-ring (C) on the output shaft (countershaft) speed sensor (D), and install the output shaft (countershaft) speed sensor and the sensor washer (E).
21. Install the shift solenoid wire harness (F) in the transmission housing with a new O-ring (G).
22. Connect the shift solenoid wire harness connectors to the shift solenoid valves:
^ BLU wire connector to shift solenoid valve A.
^ ORN wire connector to shift solenoid valve B.
^ GRN wire connector to shift solenoid valve C.
^ YEL, WHT, and WHT wire connector to shift solenoid valve D.
^ RED wire connector to shift solenoid valve E.
23. Install the shift solenoid valve cover (A) with the two dowel pins (B) and a new gasket (C).
