Periodic Inspections
The Allison MH Series requires very little
maintenance. Careful attention to the fluid
level, electrical connections and hydraulic
hoses is very important.
The transmission should be kept clean for
easy inspection. Make periodic checks for
loose bolts and leaking fluid. Regularly check
the condition of the electrical harnesses.
Occasionally check the engine cooling
system for evidence of transmission fluid
that would indicate a faulty oil cooler. Report
any abnormal condition to an Allison Service
Center.
Prevent Major Problems:
Help the control system oversee the
operation of the transmission. Minor problems
can be kept from becoming major problems
if an Allison Transmission Service center is
notified when one of these conditions occur:
Shifting feels odd.
Transmission leaks fluid.
Unusual transmission-related sounds
(sound made by normal engine
thermostatic fan cycling when climbing
a long grade with a heavy load are
often mistaken for transmission-related
sounds).
The Check Trans indicator frequently
comes on.

TRANSMISSION FLUID & FILTERS
The transmission is filled with TranSynd™
synthetic transmission fluid at the factory.
TranSynd™ synthetic transmission fluid
extends service intervals. A small tag is
been attached to the dipstick identifying that
the transmission is filled with TranSynd™
synthetic transmission fluid. A remote fill
is located at the back of the engine and a
transmission check/fill is located on the
engine.
Fluid and Filter Change Interval:
The
transmission
has two filters:
a main filter
and a lube
filter. Follow
the service intervals listed in the transmission
OEM (Original Equipment Manufacturers)
manual. Fluid and filters may require changing
earlier than recommended in the transmission
OEM manual, depending on the severity
of operating conditions. Fluid must also be
changed whenever there is evidence of dirt
or high temperature operation as indicated by
discoloration, strong odor or fluid analysis.
Local conditions, severity of operation or duty
cycle will dictate more or less frequent service
intervals.
CAUTION
DO NOT mix Dexron III®
transmission fluid with TranSynd™
Synthetic transmission fluid.
NOTE
Be sure to retain the receipt for proof
of the initial Main filter change. Refer
to the Allison transmission OEM
manual or contact an authorized
Allison service center for service
intervals.
Proper Fluid Levels:
Transmission fluid cools, lubricates and
transmits hydraulic power. Proper fluid levels
must be maintained at all times. If fluid level
is too low, the converter and clutches do not
receive an adequate supply of fluid. If fluid
level is too high, the fluid can aerate. Aerated
fluid can cause the transmission to shift
erratically or overheat.
An Oil Level Sensor (OLS) is built into the
transmission. The fluid level can be checked
easily and cleanly using the shift selector.
Check the transmission fluid level before each
trip and after removing the motorhome from
storage.
To Enter Oil Level Sense Mode:
Park the motorhome on a level surface.
Place the transmission in “N” and set
parking brake.
The transmission temperature must be
at least at operating temperature or an
error code will appear.
The motorhome must be stationary
and in Neutral for approximately two
minutes to allow the fluid to settle in
the sump.
The engine must be idling lower than
800 RPM.
Simultaneously press the Up and Down
buttons once.
