Transmission Fluid
Level Inspection
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 or brands of fluid, because of
possible incompatibility. Do not use fluid
additives, friction modifiers, or extreme-pressure
gear fluids.
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, then 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
Fig. 2.
3. If the fluid level is low, check the transmission for
leaks, and correct as needed.
NOTICE
Detroit transmissions use synthetic lubricant that
meets specific requirements. To see a list of
approved lubricants and information to identify
which transmissions they can be used with, see
the Transmission Fluid Service Information
brochure at
http://dtna.info/DT12FluidsManual.
4. If needed, add the recommended fluid until it is
level with the lower edge of the fill opening. See
the Transmission Fluid Service Information
brochure at
http://dtna.info/DT12FluidsManual
for approved transmission lubricants.
5. Clean the fill plug and install a new seal on it.
Install the plug in the side of the gear case, then
tighten it 45 lbf·ft (61 N·m).

Level Checking
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. Fluid
overflow may also drain onto the clutch or clutch
brake, causing additional problems.
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.
