MAINTENANCE AND REPAIR
ON–VEHICLE SERVICE
CHECKING FLUID LEVEL
1. With the vehicle on a level surface and the fluid in
the transaxle cold, remove the filler plug and check
the fluid level. The fluid should come to the bottom
edge of the plug hole.
2. If the level is low, add SAE 80 manual transaxle
fluid through the filler plug hole until the fluid begins
to run out.
3. Reinstall the filler plug and tighten it securely.
4. If the fluid is contaminated, drain the oil after re-
moving the differential gear cover.
