Cold Check - Manual Check Procedures:
The concept of a cold check is to determine adequate fluid level for safe
operation until hot check can be performed.
• Park the motorhome on a level surface using the service brakes.
• The engine is operated at a low idle. Put the transmission in N
(Neutral).
• Apply the parking brake and 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 run.
• If the level is not within this band, add or drain the fluid as
necessary to bring the level to the middle of the COLD
CHECK band.
• Perform the HOT CHECK 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
transmission if not corrected.
