rear grIll
The rear grill pulls out
for access to the radiator
compartment. The grill
is attached by four tabs
that insert into four
grommets, one
on each corner.
To detach, place
both hands
evenly spaced
on the grill and
gently ease the
grill out. To
reinstall, align
the tabs with the grommets and push in.
WARNING:
When reinstalling it is IMPORTANT
that the four corners of the grill are
securely attached to the four grommets.
Failure to do so may result in the grill
jarring loose with travel.
tranSmISSIon
The Allison 1000 series transmission is
a fully automatic, torque-converter driven,
electronically controlled transmission. The
electronic controls provide automatic gear
selection in all drive ranges and automatic
engagement of the torque converter lockup
clutch.
The electronic control system has ve major
components: the Transmission Control Module
(TCM), engine throttle position sensor, three
speed sensors, Neutral Start Back Up (NSBU)
switch and the control valve module. The
TCM processes information received from the
throttle position sensor, speed sensor, NSBU
switch and control valve module. The electronic
control system optimizes shift quality by using
“Adaptive Shifting.” A wide variety in shifting
under varied conditions is required before
optimizing the shift quality. Generally, ve
typical shifts of a shift type are needed for shift
calibration.
Shift Selector
The range selection
is accomplished via
the remote push button
selector. The controls
are R, N, D, arrow up,
arrow down, and a digital
display window. Under
normal operation press the
D button and the digital
display shows the highest
forward range attainable
for shift selection in use.
When the ignition is turned
ON, the display should be visible. This display
indicates the presence of neutral start command.
If the display indication is not visible, there is no
power to the selector and the transmission will
not allow the engine to start. This is an indicator
of electrical problems with the engine batteries,
ECU on shift selector keypad.
Keypad Functions:
Select the PARK gear by pressing P.
Select the REVERSE gear by pressing R.
Select NEUTRAL by pressing N. The
area around the N button has a raised
ridge so the driver can orient his hand
to the push buttons by touch, without
looking at the display.
Select DRIVE range by pressing D.
The highest forward gear appears in the
display and the transmission will shift to
rst gear though 5 is displayed.
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 gear range selected by one.
If the button is held continuously, the
selected range continues to change up
or down until the button is released or
until the highest/lowest possible range of
gears is selected.
When the Exhaust brake is used, the
display changes to a default reading of 2,
3 or 4. The transmission is not in second,
third or fourth gear. This is only a
reference for the transmission downshift
points to optimize the engine braking
effect.
