Automatic Transmission Assembly (With Transfer) Dismounting and Remounting
Automatic Transmission Assembly (with Transfer) Dismounting and RemountingDismounting
In engine room
1. Disconnect negative cable at battery.
2. Remove dipstick and oil filler tube.
On lift
1. Drain transfer oil.
2. Remove drain plug (1) and drain A/T fluid.
NOTE: If automatic transmission is overhauled later on, draining A/T fluid at this point will facilitate work.
3. Before removing propeller shaft, give match marks (1) on joint flange and propeller shaft as shown in the figure.
4. Remove universal joint flange bolts and take out rear propeller shaft.
5. Likewise, take out front propeller shaft.
6. Remove nut from the end of select cable and bracket to set cable free.
7. Remove select cable bracket by removing its 2 bolts.
8. Remove engine under cover.
9. Remove exhaust No.1 pipe, exhaust pipe brackets and exhaust No.2 pipe.
10. Remove stabilizer bar mount bush bracket bolts.
11. Remove clamp and then disconnect oil cooler hoses from pipes.
NOTE: To avoid leakage of transmission fluid, plug open ends of oil cooler pipes and hoses right after they are disconnected.
12. Remove stiffener mount bolts.
13. Remove torque converter housing cover and converter housing lower plate (1).
14. Holding crankshaft pulley bolt stationary with wrench, remove torque converter mounting bolts (1) with wrench.
15. Apply transmission jack and take off rear mounting member by removing its bolts.
16. Remove rear mounting (1) by removing its bolts (2).
17. Lower transmission jack slowly. Remove it from transmission, then install auxiliary arm (2) to transmission jack (1).
18. Raise transmission jack until it contacts transmission.
19. Disconnect connectors from VSS (4WD model only), output shaft speed sensor, input shaft speed sensor, transmission range sensor, transmission wire, 4WD low switch and transfer shift control actuator, release their wire harnesses from clamps.
20. Remove breather hose and harness clamp mounting bolts from transmission.
21. Remove starter motor bolts.
22. Remove nuts (1) fixing engine to transmission.
23. Remove bolts (1) fixing engine to transmission.
24. With transmission assembly held up on jack, move then to the rear and lower them including torque converter.
As necessary, insert a rod into the gap between drive plate (1) and torque converter (2), then separate drive plate (1) from torque converter (2).
WARNING: Transmission assembly may tilt rearward on jack. It is recommended to use an auxiliary arm of jack for the purpose of safety.
After Dismounting
WARNING: Be sure to keep transmission and transfer assembly horizontal throughout the work. Should they be tilted, torque converter may fall off and cause personal injury and A/T fluid may flow out.
1. Remove transfer breather hoses.
2. Remove transfer by removing its bolts.
Remounting
WARNING: When moving transmission assembly with torque converter equipped in it, be sure to keep it horizontal. Tilting it with its front facing down may allow converter to fall off, thereby an injury may result.
Reverse dismounting procedure for remounting noting the following points.
^ When installing transmission and transfer to engine, lift the front of engine about 10 cm (3.94 inch) by using hoist.
^ Check drive plate (1) for runout by using magnetic stand and dial gauge.
^ If runout is not within specification or ring gear is damaged. replace drive plate.
Drive plate runout limit 0.2 mm (0.079 inch)
^ Install torque converter (1) to drive plate (2) by using the torque converter mounting bolts (3) of correct length.
^ Tighten bolts and nuts to specified torque.

^ Clamp wire harness and hoses securely.
^ Refer to Select Cable Adjustment for adjusting procedure of select cable.
^ Follow fluid level check procedure for refilling automatic transmission fluid and adjusting its level.
^ Install battery, and confirm that engine and transmission function acceptably.
^ When remounting drive plate, use specified bolts.
