Hot Check
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.
Important: For oil and filter change intervals, see the applicable Allison Operator's Manual.
- Operate the transmission in a drive range until normal operating temperature, 160 to 200°F (71 to 93°C), is reached.
- Park the vehicle. Shift to neutral (N) and apply the parking brake. Let the engine run at idle.
- Wipe the dipstick clean and check the fluid level. A safe
operating level is any level within the HOT RUN (upper) band on the
dipstick. See Fig..

- If the fluid is not within this range, add or drain fluid
as needed to bring the level to the top of the HOT RUN band. See Table. for approved
transmission lubricants, and Table. for lubricant capacities.
