26–02 Transmission Fluid
Level Inspection
CAUTION
Operating a transmission with the fluid level
higher or lower than recommended can result in
transmission damage. Do not overfill the transmis-
sion. 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 addi-
tives, friction modifiers, extreme-pressure gear
fluids, or multiviscosity lubricants.
With the transmission at operating temperature, and
the vehicle on a level surface, check the fluid level in
the transmission.
1. Clean the area around the fill plug, and remove it
from the side of the gear case.
2. Using your finger or a bent pipe cleaner, see if
the fluid is level with the fill opening. See
3. If the fluid level is low, check the transmission for
leaks, and correct as needed.
4. If needed, add the recommended fluid, until it is
level with the lower edge of the fill opening. See
Table 1 for approved transmission lubricants.
5. Clean the fill plug, then install it. Tighten the plug
as follows:
• 25 to 35 lbf·ft (34 to 48 N·m) for transmis-
sions with 3/4-inch pipe threads.
• 60 to 75 lbf·ft (81 to 102 N·m) for transmis-
sions with 1-1/4-inch pipe threads.
• 44 lbf·ft (60 N·m) for all ZF Meritor
FreedomLine automated transmissions.
• 35 to 50 lbf·ft (48 to 67 N·m) for all other
Meritor transmissions.
