• Always be careful to work safely, avoid forceful or uninstructed operations.
• Never start working until exhaust system and coolant are cool enough.
• If items or work required are not covered by the engine section, refer to the applicable sections.
• Always use the support point specified for lifting.
• Use either 2-pole lift type or separate type lift as best you can. If board-on type is used for unavoid-

able reasons, support at the rear axle jacking point with a transmission jack or similar tool before
starting work, in preparation for the backward shift of center of gravity.

• For supporting points for lifting and jacking point at rear axle, refer to

GI-31, "Garage Jack and

Safety Stand and 2-Pole Lift"

.

NOTE:
When removing components such as hoses, tubes/lines, etc., cap or plug openings to prevent fluid from spill-
ing.

.

10. Preparation for the separation work of transaxle is as follows:

• Remove transaxle joint bolts which pierce at oil pan (upper) lower rear side. Refer to

EM-242, "Exploded

View"

.

Removal

1.

Use a manual lift table caddy (commercial service tool) or equiv-
alently rigid tool such as a transmission jack. Securely support
bottom of the engine and the transaxle assembly.

CAUTION:

Put a piece of wood or an equivalent as the supporting sur-
face, secure a completely stable condition.

2.

Remove upper torque rod bolt (RH).
• Loosen the mounting bolt as shown in the figure.

ing tool, such as manual lift table caddy [SST: GW86490800] or mission jack.

CAUTION:

• Check that no part interferes with the vehicle side.
• Before and during this lifting, always check if any harnesses are left connected.
• During the removal, always be careful to prevent the vehicle from falling off the lift due to

changes in the center of gravity.

• If necessary, support the vehicle by setting jack or suitable tool at the rear.
