Cold Check - Manual Check Procedures:
The concept of a cold check is to determine adequate fluid level for safe
operating until 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 operated 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
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 temperatures (160º - 200º F/71º - 93º C).
CAUTION: Low or high fluid level can cause overheating and
irregular shift patterns. These conditions can damage the trans-
mission if not corrected.
• The fluid level rises as the temperature increases. The fluid must be
hot to ensure an accurate 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 within 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.
