AFTER THE TWO MINUTE COUNTDOWN,
the shift selector
displays the oil level data as in the following examples:
OIL LEVEL READINGS MEANING OF READINGS
o L o K Fluid level is correct
o, L, L, o, 1 or OL, LO, 01 Fluid level is 1 quart low
o, L, H, I, 1 or OL, HI, 01 Fluid level is 1 quart high
3 TO EXIT THE OIL LEVEL DISPLAY MODE:
• Using the pushbutton shift selector, press the NEUTRAL button or
simultaneously press the UP and DOWN arrows twice.
• Using the lever shift selector, press the DISPLAY bu tton twice or

DISPLAYING OIL LEVEL INFORMATION
Oil level information can be displayed on the shift selector if the
transmission is equipped with an oil level sensor.
Use the following procedure to display oil level information if the
transmission is equipped with the option:
1 TO ENTER THE OIL LEVEL DISPLAY MODE:
• Using a pushbutton shift selector, simultaneously press
the UP and DOWN arrow buttons.
• Using a lever shift selector,
press the DISPLAY MODE button.
A two minute countdown begins when the
following conditions are met:
• Engine is at idle.
• Sump oil is at operating temperature.
• Transmission output shaft is stopped.
• Transmission is in neutral.
• Oil level sensor is functioning properly.
• Oil level will be displayed at the end of the two minute countdown.
During the countdown, the display flashes and a count down occurs
reducing by one digit every 15 seconds. (8, 7, 6, 5, 4, 3, 2, 1)
NOTE:
Failure to meet any of the above conditions will stop the two
minute countdown.The shift selector will display one of the following
oil level codes to show the reason for the countdown interruption. The
countdown will resume where it stopped once all conditions have been
met. Shift selectors with single digit displays will display the four digit
codes one digit at a time. Shift selectors with two digit displays will
display the codes two digits at a time.

DISPLAYING DIAGNOSTIC CODES
1 TO ENTER THE DIAGNOSTIC MODE:
• Using a pushbutton shift selector, simultaneously press the UP
and DOWN arrows once if the transmission does not hav e an oil level
sensor and twice if the transmission is equipped with an oil level sensor.
• Using a lever shift selector, press the DISPLAY MODE button
once if the transmission does not have an oil level sensor and twice
if the transmission is equipped with an oil level sensor.
2 IF NO CODES ARE PRESENT,
the display will show a dash
( - ) on a single digit display shift selector or a double dash ( - - ) on
a two digit display shift selector.
IF CODES ARE PRESENT,
the code registered in the first of five
code positions will display on the shift selector. The code list position
is the first item displayed, followed by the two digit main code and
then the two digit sub code. Each item is displayed for about one
second.The display cycles continuously until the next code list position
is selected by pressing the MODE button.
THE FOLLOWING LIST REPRESENTS A CODE DISPLAY USING
CODE 25 11 AS AN EXAMPLE:
• Code list position - d 1 (will be displayed one digit at
a time on a shift selector with a single digit display).
• Main code - 2 5 (will be displayed one digit at
a time on a shift selector with a single digit display).
• Sub code - 1 1 (will be displayed one digit at
a time on a shift selector with a single digit display).
• Cycle will continue to repeat itself.
3 TO VIEW THE CODES
in the second, third, fourth and fifth
positions (d 2, d 3, d 4, d 5), momentarily press the MODE button as
explained above in step 2. Momentar ily pressing the MODE button
when the fifth position is displayed, will restart the sequence by
displaying code position one (d 1)
.
4 IF A LISTED CODE IS ACTIVE,
the LED
indictor next to the MODE button will be illuminated on
shift selectors with a single digit display. On shift
selectors with a two digit display, the MODE ON light
will appear on the display.
CLEARING DIAGNOSTIC CODES
1 WHILE IN THE DIAGNOSTIC MODE,
push and hold the MODE
button for approximately ten seconds to clear all of the codes.Shift
selectors with two digit displays will sound a tone at about eight
seconds and a second tone at about ten seconds indicating that all
of the codes are cleared. Shift selectors with a single digit display will
flash the LED indicator three times after about 3 seconds and three
times again after about 10 seconds indicating that all of the codes
are cleared.
2 DRIVE THE VEHICLE AND CHECK FOR CODE REOCCURRENCE.
If codes continue to reoccur, bring the vehicle to an authorized
Allison Transmission repairing outlet to diagnose and repair the
problem causing the codes.
EXITING THE DIAGNOSTIC MODE
1 ON PUSHBUTTON SHIFT SELECTORS,
press the NEUTRAL
button or simultaneously press the UP and DOWN arrows.
2 ON LEVER SHIFT SELECTORS,
press the DISPLAY MODE
button or move the shift selector to any range and back to neutral.
