A Park Pawl is used with the transmission

which effectively prevents rotation of the

driveline.

WARNING:
An attempt to engage the park pawl with
the motorhome in motion will ratchet
the park pawl. The park pawl will not
hold the motorhome and will not engage.

When the motorhome is stationary, the park

pawl is automatically engaged by shifting the

shift lever to P (Park). Parking on an incline and

not following parking procedures can result in a

condition known as “Torque Lock.” Torque lock

can occur when an excessive amount of torque

is placed on the park pawl. It may be difficult to

shift the transmission out of P (Park). Setting the

Park brake before shifting to P (Park) can help

prevent torque lock.

Periodic Inspections

For easier inspection, the transmission should

be kept clean. Make periodic checks for loose

bolts and leaking fluid lines. Regularly check the

condition of the electrical harnesses. Check the

engine cooling system occasionally for evidence

of transmission fluid which would indicate a

faulty oil cooler. Report any abnormal condition

to the Allison dealer.

Prevent Major Problems

Help the electronic control system oversee the

operation of the transmission. Minor problems

can be kept from becoming major problems if

you notify an Allison Transmission distributor or

dealer when one of these conditions occur:

1. The shifting feels odd.

2. The transmission leaks fluid.

3. Unusual transmission-related sounds

(changes in sound caused by normal
engine thermostatic fan cycling,
while climbing a long grade with a
heavy load, have been mistaken for

transmission-related sounds).

4. The CHECK TRANS light comes on

frequently.

The Importance of Proper Fluid Levels

Because the transmission fluid cools, lubricates

and transmits hydraulic power, it is important

that the proper fluid level be maintained at all

times. If the fluid level is too low, the converter

and clutches do not receive an adequate supply

of fluid. If the fluid level is too high, the fluid can

aerate. Aerated fluid can cause the transmission

to shift erratically or overheat.

NOTE:
The motorhome should be stationary
for approximately two minutes prior to
checking the fluid levels to ensure fluid
is stabilized.

Transmission Fluid

A small tag has been attached to the dipstick

identifying that the transmission is filled with

TranSynd™ synthetic transmission fluid. A

transmission check/fill is located at the back of

the engine.

Fluid and Filter

Change Interval:

The transmission

has one spin-on

filter located on the

transmission bell

housing.

Follow the service

intervals listed in
the transmission

OEM (Original Equipment

Manufacturers)

manual. Fluid and filter 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.

NOTE:
Be sure to retain the receipt for proof
of the initial Main filter change. Refer
to the Allison Transmission Owner’s
Manual or contact an authorized Allison
service center for service intervals.
