Contents: Removal ↓ Installation ↓
Note: The following procedure requires removing the engine and transaxle assembly from the vehicle as a single unit, and then separating them after removal from the vehicle (for the engine and transaxle assembly removal procedure, refer to chapter 2B).
Removal
1. Remove the engine assembly with the gearbox in the block with the drive axle (see chapter 2B).
2. On 4WD models (all-wheel drive) remove the transfer case (see paragraph 8).
3. Unscrew the bolts securing the gearbox to the engine (Fig. 9.7) and separate the gearbox from the engine.
4. Check the engine and gearbox mounts (see chapter 2A or 2B). If any of these items are worn or damaged, replace them.
Installation
5. Install the torque converter on the primary shaft of the gearbox (if it was filmed). Make sure that the torque converter hub splines are properly aligned with the transmission input shaft splines.
6. Have an assistant hold the torque converter in the correct position inside the transmission while aligning the transmission in the block with the drive axle relative to the engine and tighten the pair of bolts that secure the units together. Do not over-tighten the transmission. If there is any obstruction and the transmission does not mate with the engine properly, slightly change the angle of the transmission to ensure proper fit.
Caution: Do not use the transmission-to-engine mounting bolts to force the engine and transmission together. Doing so may crack or damage major components. If you have difficulty mating, have an assistant help you properly align the dowel pins on the engine block with the matching holes on the transmission flange. Some repositioning of the engine and/or transmission may be necessary to ensure proper alignment of the two components.
Rotate the torque converter to align the bolt holes in the torque converter with the bolt holes in the faceplate. Screw in the torque converter-to-faceplate mounting bolts.
Application: Install all bolts before tightening any of them.
7. Install the remaining transmission-to-engine mounting bolts. Tighten all bolts to the specified torque as shown in Specifications at the beginning of this chapter (Fig. 9.7).

8. On 4WD models, install the transfer case (see paragraph 8).
9. Install the engine assembly with the gearbox in the block with the drive axle (see chapter 2B).
10. Reinstall the remaining components in the reverse order of removal.
11. Remove all jacks and stands and lower the vehicle. Tighten the wheel nuts to the specified torque as shown in Specifications at the beginning of this chapter. Tighten the axle/hub nuts to the specified torque as shown in Specifications at the beginning of this chapter.
12. Add engine oil and transmission fluid of the appropriate grade in the prescribed quantity (see chapter 1).
13. Connect the ground cable to the battery. Start the engine, engage all gears in the transmission one by one, and then check the transmission fluid level (see chapter 1). Check for proper operation and absence of leaks.
14. Perform a road test of the vehicle to check the correct operation of the transmission in the drive axle unit and make sure that there is no leakage of transmission fluid. Check the transmission fluid level again.
