Notice: Operating a transmission with the fluid level higher or lower than recommended can result in transmission damage. Do not overfill the transmission.
Do not mix types and brands of fluid, because of possible incompatibility. Do not use fluid additives, friction modifiers, extreme-pressure gear fluids, or multiviscosity lubricants.
- Park the vehicle on a level surface, apply the parking brakes, and chock the tires.
- Clean the area around the fill plug, then remove the plug from the side of the gear case.
- Using your gloved finger or a bent pipe cleaner, check
if the fluid is level with the fill opening. See Fig..

-
25 to 35 lbf·ft (34 to 48 N·m) for transmissions with 3/4-inch pipe threads.
-
60 to 75 lbf·ft (81 to 102 N·m) for transmissions with 1-1/4-inch pipe threads.
