General Information
Control. Power. Information. The new 5th Generation Electronic Shift Selector from Allison puts it all at your fingertips. Literally. Getting started is easy and the selector’s complete menu of prognostic and diagnostic tools minimize downtime and keep you on the job. Use this handy reference booklet for step-by-step instruction on how to get the most from your shift selector and of course, your Allison fully automatic transmission.
The Allison Advantage
Your Allison Automatic is fully electronically controlled. The Allison electronic controls package oversees the operation of the transmission, controlling transmission upshifts and downshifts, and providing important information on the operation of your drive system.
Through readouts on your shift selector, you will be able to monitor transmission oil levels, read diagnostic codes and prognostic information. This manual will help you understand shift selector readouts and enjoy long, trouble-free operation of your Allison Automatic.
Diagnostics
The Transmission Control Module (TCM) of your Allison Automatic monitors the transmission’s electronic controls; and when a problem condition is detected, it:
• May restrict shifting
• Illuminates the CHECK TRANS* light on the instrument panel
• Registers a diagnostic code
Continued illumination of the CHECK TRANS light during vehicle operation (other than start-up) indicates that the TCM has signaled a diagnostic code.
NOTE: Displays apply only when using a 5th Gen TCM.
* For some problems, diagnostic codes may be registered without the TCM
activating the CHECK TRANS light. Your Allison Authorized Service Network should be consulted whenever there is a transmission-related concern. They have the equipment to check for diagnostic codes and to correct problems.

Basic Operation
5th Generation Electronic Controls Shift Selectors
As the world leader in medium- and heavy-duty commercial transmissions, Allison Transmission continues its ongoing improvement initiative with the introduction of 5th Generation Electronic Controls Shift Selectors.
All 5th Generation Electronic Controls Shift Selectors feature easy-to-read graphic displays that show both text and symbols.

OEMs may supply shift selectors for some vehicles equipped with 5th Generation Electronic Controls. If your vehicle is not equipped with an Allison-supplied shift selector, contact your OEM.
Mode Button
Allison Automatics offer primary and secondary shift schedule modes to enhance performance or fuel economy. The vehicle always defaults to the primary mode [MODE is not shown on graphic display]. If equipped as such you can switch to the secondary mode by pushing the MODE button [MODE is shown on graphic display].
Your vehicle may be equipped with FuelSense – Allison’s next generation in fuel-savings technology. FuelSense is a set of unique packages of software and electronic controls that can potentially increase fuel economy by 20%. FuelSense icons will appear at start up if your vehicle utilizes a FuelSense package.

SECTION 1
WITH PROGNOSTICS + WITH OIL LEVEL SENSOR
Fluid Levels
The transmission fluid cools, lubricates and transmits hydraulic power, so it is important that the proper fluid level be maintained at all times. If the fluid level is too low, the converter and clutches do not receive an adequate supply of fluids. If the fluid level is too high, the fluid can aerate causing the transmission to shift erratically or overheat.
Checking Fluid Levels
Use the following procedure to display oil level information.
To enter the oil level function:
1. Park the vehicle on a level surface, shift to N (NEUTRAL)
and apply the parking brake.
2. Using a pushbutton shift selector, simultaneously
press the UP and DOWN arrows one time.
For a bump lever shift selector, press the DIAGNOSTICS button one time.
3. The fluid level reading will be delayed until the following conditions are met.
• Engine must be at idle.
• Transmission is in N (NEUTRAL).
• Output speed must be zero.
• Fluid temperature must be between 104F (40C)
and 220F (104C).
• Vehicle has been stationary for two minutes to allow the fluid to settle.

4. The shift selector displays the oil level data as follows:
CORRECT FLUID LEVEL – The fluid is within the
correct fluid level zone when OK is shown.
LOW FLUID LEVEL – The display shows the number
of quarts the transmission oil is low.
HIGH FLUID LEVEL – The display shows the number
of quarts the transmission oil is overfilled.
Delayed Fluid Level Check
If the fluid level check cannot be completed, one of the following Oil Level Display faults will be shown:
To exit the oil level function:
• For pushbutton shift selector,
press N (NEUTRAL) button.
• For bump lever shift selector, press the
DIAGNOSTICS button until you return to range display.
Prognostic Features
5th Generation Electronic Controls Shift Selectors display prognostics in text form to provide at-a-glance status of Oil Life, Filter Life and Transmission Health.
The WRENCH ICON will illuminate briefly after you turn the key to the run position on your Allison-equipped vehicle to indicate that prognostics are enabled. If the WRENCH ICON remains on or flashes, this indicates there is a service issue relating to clutch, filter or fluid life.

Transmission Health Monitor (not available for TC10)
The status of transmission health is displayed as OK or LO.
Accessing Prognostics
When you are alerted via the WRENCH ICON on the shift selector that service is due, you can check the status by toggling through the shift selector display as follows. Be sure to park the vehicle on a level surface, shift to
N (NEUTRAL) and apply the parking brake before accessing prognostics through the shift selector.
