Housing and Shaft Assemblies Removal/Installation
Housing and Shaft Assemblies Removal
Special Tools Required
Housing puller 07HAC-PK40102
NOTE: Refer to the Exploded View as needed during this procedure.
1. Remove the A/T clutch pressure control solenoid valves A and B.
2. Remove the transmission housing mounting bolts.
- '98-00 models: Remove the 16 bolts, hangers, and brackets.
- '01-02 models: Remove the rear stiffener and special bolt, then remove 15 bolts, hanger, and brackets.
3. Install a 5 x 0.8 mm bolt (A) in the reverse idler gear shaft (B), then remove the reverse idler gear shaft/ holder assembly (C).
4. When removing the transmission housing from the torque converter housing, move the reverse idler gear out of way of the countershaft 2nd gear in the direction shown.
NOTE: The transmission housing will not separate from the torque converter housing if the reverse idler gear is not moved.
5. Align the spring pin (A) on the control shaft (B) with the transmission housing groove (C) by turning the control shaft.
6. Install the special tool over the mainshaft, then remove the transmission housing.
NOTE: If the top arm of your housing puller is too short, replace it with Housing Puller Arm, 205 mm, 07SAC-P0Z0101.
7. Remove the reverse idler gear from the transmission housing.
8. Remove the countershaft 2nd gear, then slide and remove the countershaft reverse gear and the needle bearing.
9. Remove the bolt securing the shift fork, then remove the shift fork, reverse selector, reverse selector hub, and countershaft 4th gear. If the reverse selector hub is press-fitted, leave it and 4th gear on the countershaft.
10. Remove the secondary shaft sub-assembly. If the reverse selector hub is press-fitted, remove the secondary shaft sub-assembly, countershaft sub-assembly and mainshaft sub-assembly together.
11. Remove the mainshaft sub-assembly.
12. Remove the countershaft sub-assembly.
13. Remove the differential assembly.
Bearing Replacement
Special Tools Required
- Driver 07749-0010000
- Driver 07949-3710001
- Driver attachment 07JAD-PH80101
- Attachment, 72 x 75 mm, 07746-0010600
NOTE: Coat all parts with ATF before assembly.
1. To remove the mainshaft bearing (A), countershaft bearing (B), and secondary shaft bearing (C) from the transmission housing, expand each snap ring with the snap ring pliers, then push the bearing out using the special tools and a press.
NOTE: Do not remove the snap rings unless it's necessary to clean the Grooves in the housing.
2. Install the bearings in the direction shown.
3. Expand each snap ring with the snap ring pliers, and insert the bearing part-way into the housing using the special tools and a press.
4. Release the pliers, then push the bearing down into the housing until the snap ring snaps in place around it.
5. After installing the bearings verify the following:
- The snap rings (A) are seated in the bearing and housing grooves.
- The ring end gaps (B) are correct.
Shaft Assemblies and Housing Installation
NOTE: Refer to the Exploded View as needed during this procedure.
1. Install the differential assembly, countershaft subassembly, mainshaft sub-assembly, and secondary shaft sub-assembly in the torque converter housing.
2. Install the countershaft 4th gear and reverse selector hub on the countershaft. If the reverse selector hub is a press-fitted type, refer to the installation.
3. Turn the shift fork shaft (A) so the large chamfered hole is facing the fork bolt hole. Then install the shift fork (B) and reverse selector (C) together on the shift fork shaft and countershaft (D). Secure the shift fork to the shift fork shaft with the lock bolt (E) and a new lock washer (F), then bend the lock washer against the bolt head.
4. Install the needle bearing, countershaft reverse gear, and countershaft 2nd gear on the countershaft.
5. Place the reverse idler gear in the transmission housing in the direction shown, then move it the direction shown.
6. Align the spring pin (A) on the control shaft (B) with the transmission housing groove (C) by turning the control shaft.
7. Install three dowel pins and a new gasket on the torque converter housing.
8. Place the transmission housing on the torque converter housing, then install the housing bolts along with the transmission hanger/connector bracket (A), transmission hangers (B), and transmission ground terminal bracket (C). Tighten the bolts and new special bolt ('01-02 models) (D) in two or more steps in the sequence shown to 44 Nm (4.5 kgf-cm, 33 ft. lbs.).
9. Install the ATF feed pipes (A) with their filter (B) side into the transmission housing, then install new O-rings (C), new gasket (D), harness clamp bracket (E) and the A/T clutch pressure control solenoid valves A and B (F) over the ATF feed pipes on the transmission housing.
10. Coat the reverse idler gear shaft (A), needle bearing (B), and new O-rings (C) with lithium grease lightly. Assemble the new O-rings and 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 of the shaft with the D-shaped area of the holder.
11. Engage the reverse idler gear (A) with the countershaft reverse gear and mainshaft reverse gear, then install the reverse gear shaft/holder assembly (B) on the transmission housing.
