Fluid
Refer to the Maintenance Schedule to determine what
kind of transaxle fluid to use. See Part D:
Recommended Fluids and Lubricants on page 6-16 .

fluid to bring the level into the cross-hatched area on the
dipstick.

2. Using a long-neck funnel, add enough fluid at the
dipstick hole to bring it to the proper level.
It doesn't take much fluid, generally less than
one pint (0.5 L). Don't overfill.
