TRANSMISSION
The Allison World transmission incorporates the World Transmission Electronic Control (WTEC) system. The
system is compromised of fi ve major components connected by a wiring harness: the Electronic Control Unit
(ECU), engine throttle position sensor, three speed sensors, remote shift selector (keypad) and the control module.
The ECU processes information received from the throttle position sensor, speed sensor, pressure switch and
shift selector to provide optimum shift quality. This is accomplished by matching transmission and engine RPM
during a shift to establish a desired shift profi le within the ECU. Another feature of the transmission is the ability
to “learn” or “adapt.” The electronic control system optimizes shift quality by using “Adaptive Shifting.” A wide
variety of varied shift conditions is required before optimizing shift quality. Generally, fi ve typical shifts of a
consistent shift type are needed to optimize shift quality.
Shift Selector
The keypads on the shift control are R (Reverse), N (Neutral), D (Drive), Arrow up, Arrow down, Mode button.
A digital display window shows gear selection, various transmission modes, oil level and transmission fault codes.
An N (Neutral) should appear in the display window when the ignition is turned On. This indicates the
transmission is in neutral and it is safe to start the engine. If the N does not display when the ignition is turned
on, there is no power to the shift selector and the transmission will not allow the engine to start. No display is an
indicator of electrical problems with the engine batteries, ECU or the shift selector.
Keypad Functions:
• 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 (6th gear) appears in the
display and the transmission will shift to fi rst gear.
• The
Up
and
Down
arrow buttons are used to select a higher (if not in “6”) or lower
(if not in “1”) forward range. These buttons are not functional in Neutral or Reverse.
When in Drive, one press changes the gear range selected by one. 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 Mode button enables a secondary shift point to be selected. This is commonly
referred to as Economy Mode. Economy mode affects the upshift schedule 3-4, 4-5,
5-6 and downshift schedule 6-5, 5-4, 4-3. During highway driving, with the cruise
control set between 55 and 65 m.p.h., setting the transmission to Economy Mode will
eliminate about 99% of transmission downshifts from sixth to fi fth when incurring a
slight incline or overpass.
In city driving, with the transmission set to Economy Mode, the transmission will upshift approximately 200
RPM sooner using less fuel with reduced engine noise. Do not use Economy Mode while traveling in mountain
terrain. The lower RPM shift schedule will reduce the fl ow of antifreeze, lubricating oil and airfl ow through the
radiator, resulting in increased transmission and engine temperature.
•
To Enter Economy Mode:
Press the
Mode
button. The LED will illuminate.
• To Exit Economy Mode: Press the Mode button. The LED will extinguish.
