Fluid and Internal Filters Change Interval Recommendations:
The fluid and internal filters may require changing earlier depending on the
severity of operating conditions. The fluid must also be changed whenever
there is evidence of dirt or high temperature operation as indicated by discol-
oration, strong odor or fluid analysis. Local conditions, severity of operation or
duty cycle will dictate more or less frequent service intervals. Contact an
authorized Allison Service center for change intervals.
Change the transmissions filter after the first 8,000 km (5,000 miles of
operation). Following filter changes will be every 80,000 km (50,000 miles) or
24 months, whichever occurs first. Change the transmission fluid and filter
every 160,000 km (100,000 miles) or 48 months, whichever comes first.
The
internal filter is only changed at overhaul.
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 transmission if not corrected.
