Recently while traveling west on I-10, my dash alarm went off and the trans check lite came on. I looked at the two digit display on my allison 6 speed and it had what looked like snake eyes displayed.
I pulled over to the side and stopped. Pushing the buttons did nothing to change the display. Being new to this rig, I didn't know what was going on. The engine was still running and it would move forward in given fuel. I switched off the engine to see if the trans would reset. Big mistake. The engine would not crank.
Called Foretravel tech support and they walked me through a lenghtly check, but it appeared to be the ECU. Required being towed to nearest Allison shop where they confirm ECU failure.
Allison does not rebuild this unit or take your old unit for core charge. The base unit is $2,000.00 plus $820.00 to program said unit.
Equipment Description:
1993 Foretravel GV
Cummins 8.3 (105000 Miles)
Allison MH3060 6 Sp
Side Note: Do not shut off engine if this happens. The engine will have to be jump started so unit can be towed with drive shaft attached.
