Transmission Oil Level - Test



Illustration 1g06101349
(1) Dipstick
(2) Fill plug
(3) Drain plug

Check the transmission oil level with the engine idling and transmission oil cold.

Remove the dipstick (1), wipe clean, and reinsert into dipstick tube. Remove the dipstick to check oil level. The oil level should be between the "MIN" and "MAX" markings on the dipstick.

Note: At normal operating temperature the oil level will rise 20 to 30 mm (0.8 to 1.2 inch) above the "MAX" mark.

Do not overfill the transmission. Overfilling may result in oil breakdown due to excessive heat and aeration from the churning action of the gears. Overfilling may also cause oil leaks.
