Oil level information, diagnostic codes and prognostic features for
3000/4000 SERIES ALLISON TRANSMISSIONS
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.
Shift Selector Models
Detailed information on oil levels, diagnostic codes and prognostic features for your specific shift selector can be found on the following pages.
If your vehicle has a shift selector that has a:
-Double-digit display and was release after July 2008, equipped with Model Year ’09 prognostics, see the section for Model Year ’09 4th Generation Electronic Controls Shift Selectors.
-Double-digit display and was released after July 2008, not equipped with prognostics, see the section for
4th Generation Electronic Controls Shift Selectors.
-Double-digit display and was released prior to July 2008, see the section for 4th Generation Electronic Controls Shift Selectors.

General Information
FLUID LEVELS
The transmission fluid cools, lubricates and transmits hydraulic power, so it is important 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.
DIAGNOSTICS
The Transmission Control Module (TCM) of your Allison Automatic monitors the transmission’s electronic controls; and when a problem condition is detected, it:
–Restricts 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.
*For some problems, diagnostic codes may be registered without the TCM activating the CHECK TRANS light. Your Allison Transmission authorized service outlet should be consulted whenever there is a transmission-related concern. They have the equipment to check for diagnostic codes and to correct problems.

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.
OIL LIFE MONITOR
Using a pushbutton shift selector simultaneously press the UP and DOWN arrows two times.
Using a lever shift selector press the DIAGNOSTICS button two times.
“oM” appears followed by a number, from 99 to 0, which represents the percentage of oil life remaining before a fluid change is required.
FILTER LIFE MONITOR
Using a pushbutton shift selector simultaneously press the UP and DOWN arrows three times.
Using a lever shift selector press the DIAGNOSTICS button three times.
“FM” appears followed by either “oK” or “Lo”. “oK” means filters do not need to be changed and “Lo” means filters need to be changed.
TRANSMISSION HEALTH MONITOR
Using a pushbutton shift selector simultaneously press the UP and DOWN arrows four times.
Using a lever shift selector press the DIAGNOSTICS button four times.
