CHASSIS INFORMATION — 10
2008 LAPALMA XL
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 difcult 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 uid lines. Regularly check the
condition of the electrical harnesses. Check the
engine cooling system occasionally for evidence
of transmission uid 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 uid.
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 uid cools, lubricates
and transmits hydraulic power, it is important
that the proper uid level be maintained at all
times. If the uid level is too low, the converter
and clutches do not receive an adequate supply
of uid. If the uid level is too high, the uid can
aerate. Aerated uid 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 lled with
TranSynd™ synthetic transmission uid. A
transmission check/ll is located at the back of
the engine.
Fluid and Filter
Change Interval:
The transmission
has one spin-on
lter located on the
transmission bell
housing.
Follow the service
intervals listed in
the transmission OEM (Original Equipment
Manufacturers) manual. Fluid and lter 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 uid 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.
