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:

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
outlet should be consulted whenever there is a transmission-related concern.
They have the equipment to check for diagnostic codes and to correct problems.
