My 06 with 119k om the clock has had some shift inhibited odes lately, first time was after it had set for almost a month, then it has done it more as the weather gotten cold. The only code it shows on my ppe is 0700. Once I reset codes it runs great. Trans has never been limped form hammering on it. Has had a transgo jr since 1600 miles. Run the ppe level 4, but don't beat on my truck, it has had an easy life. What am I looking at?

You Can Not Diagnose an Allison Without Codes. Period! Pissing in the wind only gets you wet and smelly.:thumb:
