3) Manually move the transmission as far as possible toward
the rear of the vehicle (into the space between the No.3
crossmember
3 and the floor panel 4 .
4) Lower the clutch housing end of the transmission toward the
transmission jack.
The rear of the transmission is supported by the No.3
crossmember at this time.
5) Firmly grasp the transmission rear cover (1st mechanic).
Raise the transmission jack toward the transmission (2nd
mechanic).
Carefully lower the transmission onto the transmission jack.
The transmission must be centered on the transmission
jack.




8. Carefully pull the transmission jack with the transmission
from beneath the vehicle.

Important Operations - Installation
Follow the removal procedure in the reverse order to perform
the installation procedure.
Pay careful attention to the important points during the
installation procedure.





Transmission
1. Apply a thin coat of molybdenum disulfide grease to the top
gear shaft spline.
2. Place the transmission on a transmission jack.
3. Carefully move the transmission jack and transmission into
position behind the engine.





4. Slowly operate the transmission jack to raise the
transmission until the rear of the transmission is at the
same level as the No.3 crossmember
1 .
5. Manually support the transmission rear cover.
Move the transmission into position between the No.3
crossmember and the floor panel
2 .



6. Slowly raise the transmission jack until the front of the
transmission is aligned with the rear of the engine.
The slope of the engine and the transmission must be the
same.
7. Install the gear control box the transmission.
8. Align the top gear shaft spline with the clutch drive plate
spline.
9. Install the transmission to the engine.
Tighten the transmission nuts and bolts as shown in the
figure.
