Fluid Levels - Cold Check
Cold Check - Manual Check Procedures:
The concept of a cold check is to determine adequate fluid level for safe
operating until a hot check can be performed.
To Check the Fluid When Cold:
• Park the motorhome on a level surface. Set the parking brake.
• With the engine operating at a low idle, put the transmission in N (Neutral).
• Chock the wheels to prevent the motorhome from moving.
• Allow the engine to run at idle (500-800 RPM) for one minute.
• Apply the service brakes and shift to D (Drive), then to N (Neutral) and next to R (Reverse) to
fill the system. Finally shift to N (Neutral) and release the service brakes. Allow the engine
to continue to run at idle (500-800 RPM).
• Remove the dipstick and wipe clean. Reinsert the dipstick fully into the tube, then remove to
check fluid level. Repeat, to verify 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 temperatures
(160º - 200º F/71º - 93º C).
CAUTION:
Low or high fluid level can cause overheating and irregular shift patterns. These con-
ditions can damage the transmission if not corrected.
Fluid Levels - Hot Check
• Fluid level rises as temperature increases. Fluid must be hot to ensure an accurate check.
• Be sure 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 - 800 RPM).
• After wiping the dipstick clean, check the fluid level. Safe operating level is anywhere within
the HOT RUN band on the dipstick.
• The width of the HOT RUN band is approximately one quart of fluid at normal tempera-
ture 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.
• Ensure that fluid level checks are consistent. Check the level more than once. If readings
are not consistent, ensure the transmission breather is clean and not clogged. If readings
are still not consistent, contact the nearest Allison distributor or dealer.
