CHECKING FLUID LEVEL

Note. Vehicle must be at normal operating temperature (180-200 degrees) when checking fluid level. One pint of fluid raises level from ADD to FULL mark on dipstick in a hot transmission. DO NOT overfill.

Transmissions and transfer cases use Dexron-IIE ATF. Although Dexron-IIE is recommended, Dexron-II may still be used. Dexron-II will eventually be replaced with Dexron-IIE.
