  • Location of Allison TCU

    Posted by Michael on October 17, 2016 at 3:06 am

    Having a recurrent shifting problem in my coach which has Allison B-500R transmission. On the road and no where near an Allison shop. Last time ( 2.5 years ago) it was bad ground to TCU. Have tried to locate the thing but can’t. Suspect it is in Driver’s door bay but can’t seem to identify it. Anyone help me locate the thing? Maybe I can fix this myself. Keeps popping out of gear into neutral when shifting fron 2nd to 3rd. A real pain when trying to merge onto California freeways!
