Warning
-
• Improperly jacking a transaxle is dangerous. It can slip off the jack and may cause serious injury.
-
Caution
-
• To prevent the torque converter and transaxle from separating, remove the transaxle without tilting it toward the torque converter.

2. Remove the torque converter nuts from the starter installation hole.
No.4 engine mount bracket removal note
-
Caution
-
• A slot has been adopted for the No.4 engine mount bracket installation hole. If the No.4 engine mount bracket is deviated from the original position when installing the No.4 engine mount, engine noise or vibration could increase. When removing the No.4 engine mount, place alignment marks on the No.4 engine mount bracket so that they can be assembled to the same positions as before removal.
1. Place alignment marks on the locations shown in the figure so that they can be assembled to the same positions as before removal.
-
Note
-
• Paint so that the outline of the nut is framed on the bracket side.
2. Remove the No.4 engine mount bracket.
Transaxle Mounting Bolts (Lower Side) Removal Note
1. Adjust the SST and lean the engine toward the transaxle.
2. Support the transaxle on a jack.
3. Remove the transaxle mounting bolts (lower side).
4. Remove the transaxle.
