Transmission Key Pad:
The function of each position of the keypad push-button shifter is as follows:
• Select the REVERSE gear by pressing R.
• Select NEUTRAL by pressing N. The area around the N button is a
raised ridge so the driver can orient hand to the push buttons by
touch, without looking at the display.
• Select DRIVE range by pressing D. The highest forward gear appears
on the SELECT display and the transmission will shift to the starting
gear.
• The UPSHIFT and DOWNSHIFT arrow buttons are used to select a
higher (if not in D) or lower (if not in 1) forward range. These buttons
are not functional in NEUTRAL or REVERSE. One press changes the
range selected by one range. If the button is held continuously the
selected range will continue to change up or down until the button is
released or until the highest/lowest possible range of gears is selected.
• The fluid level of the transmission can also be checked from the shift
selector keypad. Press the up and down arrow button simultaneously
while the motorhome is at a rest position. This activates the diagnostic
circuitry of the transmission. To exit the diagnostics press N.
NOTE: The oil level sensor method of checking the fluid level
compensates for transmission fluid temperature between 60º C
- 104º C (140º F - 220º F). Any temperature below 60º C(140º
F), or above 104º C (220º F) will result in an Invalid for
Display condition.
• The MODE button will enable the secondary shift point to be selected.
The transmission shift point used will be 200 rpm lower. It is further used
by a service technician to access diagnostic codes when troubleshooting.
The diagnostic circuitry must be enabled to display the codes.
To Enter Economy Mode:
Press the MODE button. The LED will illuminate.
To Exit Economy Mode:
Press the MODE button. The LED will extinguish.
• When the Auxiliary Braking device is used, the display will change to
default reading of two or three. This default is pre-selected at the factory
and can only be reprogrammed by an authorized Allison Service center.
The transmission is not in second or third gear. This is only the reference
for the rpm shifts points to optimize the braking capacity.
CAUTION: Do not use the economy mode in heavy stop and go
traffic or mountainous terrains. While in economy mode using
heavy throttle applications with frequent shifting will raise
transmission fluid temperature. Exit economy mode until road
conditions improve.
