Electrical Troubleshooting:
If there is no power to the Shift-by-Wire System when the ignition is on, check the following fuses and
connections at the front distribution panel located below the driver’s window:
• Check the fuse inside the bay door to the right. The fuse holder is labeled “
TRANS 15
.”
• Check ignition fuses on electrical panel.
• Check the grounds located at the ground posts on the right side of the fuse panel.
Remove the Shift Selector from the Console (two U-brackets from underneath) and check to see of the
connector in the back is fi rmly plugged in. If it is, run a continuity check of each of the wires listed above.
If the display still does not illuminate, replace the Shift Selector. If the Shift Selector display illuminates and
the transmission does not shift into the various ranges, inspect the two connectors on the Actuator Assembly on
the left side of the transmission. One is on a pigtail, and the other is plugged directly into the position sensor. Ensure
both connectors are in good condition (no pushed out pins or damage) and properly connected.
Transmission Check Light
The electronic control system is programmed to inform the operator of a problem with the transmission
system and automatically take action to protect the operator, motorhome and transmission. When the TCM detects
a range inhibit or shift inhibit condition, the TCM restricts shifting, turns the
CHECK TRANS
light on the
instrument panel and registers a diagnostic code.
NOTE:
For some problems, diagnostic codes may be registered without the ECU activating the
CHECK TRANS light. The 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 which arise.
Each time the engine is started the
CHECK TRANS
will light, then turn off after a few seconds. This
momentary lighting is to show that the status light circuits are working properly. If the
CHECK TRANS
light does not illuminate during start up, or if the light remains on after start up, the system should be checked
immediately. Continued illumination of the
CHECK TRANS
light during vehicle operation (other than start up)
indicates that the TCM has signaled a diagnostic code.
Preventive Measures
Help the electronic control system oversee the operation of the transmission. Minor problems can be kept
from becoming major problems if you notify an Allison Transmission distributor or dealer when one of these
conditions occur:
1. The shifting feels odd.
2. The transmission leaks fl uid.
3. Unusual transmission-related sounds (changes in sound caused by normal engine thermostatic fan
cycling, while climbing a long grade with a heavy load, have been mistaken for transmission-related
sounds).
4. The CHECK TRANS light comes on frequently.
