• Remove the dipstick and wipe clean. Reinsert the dipstick fully into the tube and remove to check
fluid level. Repeat this to verify the reading if needed.
• Safe operating level is anywhere within the COLD CHECK band on the dipstick. The fluid
level is sufficient enough to operate until a HOT CHECK can be performed.
• If the level is not within this band, add or drain the fluid as necessary to put the level to the
middle of the COLD CHECK band.
• Perform the HOT CHECK at the first opportunity after reaching normal operating temper-
atures (160º - 200º F/71º - 93º C).
CAUTION:
Low or high fluid level can cause overheating and irregular shift patterns. These
conditions can damage the transmission if not corrected.
Transmission Fluid Level - Hot Check
• The fluid level rises as the temperature increases. The fluid must be hot to ensure an accu-
rate check.
• Be sure the fluid has reached normal operating temperature (160º - 200º F/71º - 93º C). If a
transmission temperature gauge is not present, check the fluid level when the engine water
temperature gauge has stabilized and the transmission has been operated under the load for
at least one hour.
• Park the motorhome on a level surface and shift to N (Neutral). Apply the parking brake and
allow the engine to idle (500 to 800 RPM).
• After wiping the dipstick clean, check the fluid level. Safe operating level is anywhere with-
in the HOT RUN band on the dipstick.
• The width of the HOT RUN band is approximately one quart of fluid at normal temperature
range.
• If the level is not within this band, add or drain the fluid as necessary to put the level within
the HOT RUN band.
• Be sure that the fluid level checks are consistent. Check the level more than once. If the
readings are not consistent check to be sure that the transmission breather is clean and not
clogged. If the readings are still not consistent, contact the nearest Allison distributor or
dealer.
