Eaton Fuller Transmission Fluid Change, and Magnetic Plug Cleaning
- If the transmission fluid is not at normal operating temperature, run the engine until the fluid reaches operating temperature.
- Park the vehicle on level ground, apply the parking brakes, shift the transmission to neutral (N), shut down the engine, and chock the tires.
- Place a large drain pan under the transmission.
- Clean the area around the fill plug, and remove it from the side of the gear case. Remove each drain plug from the bottom of the case.
- Clean the fill and drain plugs. For magnetic plugs, use
a piece of key stock or any other convenient steel slug to short the
two magnetic poles and divert the magnetic field.Install and tighten each drain plug 50 lbf·ft (68 N·m).
- For a transmission equipped with a transmission fluid filter(s),
replace the fluid filter(s) as follows.
- Place a drain pan under the transmission fluid filter.
- Place a strap or chain wrench around the filter canister, and rotate it in a counterclockwise motion to separate the filter from the mounting. Carefully spin the filter off the mount and remove it from the vehicle.
- Apply a light coat of transmission fluid to the O-ring gasket on the new filter. Fill the filter with specified transmission fluid, and spin the filter onto the mount.
- Once the filter makes contact with the mount, use a strap wrench to rotate the canister an additional 180 to 270 degrees to firmly tighten the filter. Wipe the filter clean of any fluid after it is tightened.
Caution: To prevent skin burns from hot transmission fluid, wear protective gloves when removing the filter.
Note: The filter fills slowly, so be patient to ensure the proper fluid level has been reached.
- Add Eaton-approved fluid until it is level with the lower
edge of the fill opening. See Table. for approved transmission lubricants, and Table. for
transmission lubricant capacities.For more information and a complete listing of approved lubricants, refer to the Eaton website, www.roadranger.com.

- Operate the engine for five minutes after filling the transmission, then check the fluid level again.
- Clean the fill plug, then install it in the transmission.
Tighten the plug as follows:
-
25 to 35 lbf·ft (34 to 48 N·m) for Eaton Fuller transmissions with 3/4-inch pipe threads.
-
60 to 75 lbf·ft (81 to 102 N·m) for Eaton Fuller transmissions with 1-1/4-inch pipe threads.
-
- Operate the vehicle to check for correct operation.
Notice: Operating a transmission with the fluid level higher or lower than recommended can result in transmission damage. Do not overfill the transmission. Overfilling will force fluid out of the case through the main shaft openings.
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.
Note: Fluid change intervals are extended to 500,000 miles (800 000 km) on any vehicles filled with synthetic transmission fluid.
Note: The optional transmission fluid filter may be a remote-mount, spin-on type, located between the transmission and the fluid cooler. The filter bracket is attached to the frame rail or some other nearby location. The filter is mounted in a vertical position, and should be filled with fluid before installation to assure the proper fluid level. For optimum transmission performance, change the filter each time that the fluid is changed.
Note: In all cases, the correct fluid level is established by checking at the fill opening.
