CAUTION: DO NOT operate the transmission for extended periods of
time until a Hot Check has veri fi ed proper fl uid level. Transmission
damage can result from extended operation at improper fl uid level
conditions.
CAUTION: Obtain an accurate fl uid level by imposing the following
conditions:
• Engine is idling (500–800 rpm) in N (Neutral)
•
Transmission fl uid is at the normal operating temperature
•
The vehicle is on a level surface
HOT CHECK
The transmission fl uid must be hot to obtain an accurate check, because the fl uid
level rises as temperature increases.
To perform a HOT CHECK, do the following:
1. Be sure fl uid has reached normal operating temperature (71°–93°C;
160°–200°F). If a transmission temperature gauge is not present, check
fl uid level when the engine water temperature gauge has stabilized and the
transmission has been operated under load for at least one hour.
2. Park the vehicle on a level surface and shift to N (Neutral). Apply the
parking brake and allow the engine to idle (500–800 rpm).
3. Remove the dipstick and wipe it clean. Insert the dipstick into the fi ll tube,
pushing down until it stops.
4. Remove the dipstick and observe the fl uid level. The safe operating level is
anywhere within the HOT RUN band on the dipstick.
5. If the level is not within this band, add or drain fl uid as necessary to bring
the level within the HOT RUN band.
6. Be sure fl uid level checks are consistent. Check level more than once and
if readings are not consistent, check to be sure the transmission breather is
clean and not clogged. If readings are still not consistent, contact your
nearest Allison distributor or dealer.
