CAUTION:
Engine temperature may rise when
ascending long grades using full throttle.
Towing a load will increase the demand
on the engine. If this occurs, manually
shift the transmission down to the next
lower gear and use less throttle. The
engine will use less fuel and RPM’s
should increase.
NOTE:
The transmission will not accept a
manually selected gear change to occur
if the gear selected is out of the specified
operating range.
NOTE:
The transmission will not shift into gear
if the engine RPM is at or above 900.
The display will flash “5” indicating the
engine RPM is excessive. Select “N” and
lower the engine RPM.
Shift Inhibits
Shift inhibits fall within certain categories.
Above-idle neutral range shifts are shifts from
N (Neutral) to R (Reverse) or N (Neutral) to a
forward range when the idle is in excess of 900
rpm (Above-idle). Forward/Reverse directional
shifts are not permitted when measurable output
shaft speed is detected.
NOTE:
Sudden movements or lurching the
motorhome with an open throttle can
result in damage to transmission. Avoid
this condition by making shifts only
when the throttle is closed and engine is
at normal idle.
Certain unusual transmission operating
conditions detected by the TCM will temporarily
limit transmission operations. These conditions
are transmission problems. The TCM will lock
the Transmission in a safe gear range to permit
the motorhome to be driven to a service location.
The TCM may not respond to additional shift
requests. Upshift and downshift may not occur
and directional changes will not occur.
Check Trans - Indicator (On Dash)
The electronic control system is programmed
to inform the operator of a problem with the
transmission system and automatically take
action to protect the operator, motorhome and
transmission. When the TCM detects a Range
inhibit or Shift inhibit condition, the TCM
restricts shifting, turns the CHECK TRANS
light on the instrument panel and registers a
diagnostic code.
NOTE:
For some problems, diagnostic codes
may be registered without the ECU
activating the CHECK TRANS light.
The Allison Transmission authorized
service outlet should be consulted
whenever there is a transmission related
concern. They have the equipment to
check for diagnostic codes and to correct
problems which arise.
Each time the engine is started the CHECK
TRANS will light, then turn off after a few
seconds. This momentary lighting is to show that
the status light circuits are working properly. If
the CHECK TRANS light does not illuminate
during start up, or if the light remains on
after start up, the system should be checked
immediately. Continued illumination of the
CHECK TRANS light during vehicle operation
(other than start up) indicates that the TCM has
signaled a diagnostic code.
Parking
Bring the motorhome
to a complete stop
using the service brakes and hold the brake
pedal down.
Allow the engine to come to a
low idle (500 to 800 rpm).
Apply the parking/
emergency brake by pulling up on the knob.
Only after the parking/emergency brake is set,
then move the shifter to the P (PARK) position.
This engages the park pawl. Release the brake
pedal.
NOTE:
Chock all the wheels securely if the
motorhome is left unattended.
