Location of Allison TCM in 2014 Tuscany XTE
My coach is sending somewhat random transmission codes--P0711. By the time an Allison tech can look at it, code always inactive; therefore no diagnosis has been made. I have suggested that the outside temperature has something to do with it--the internal transmission temp has remained normal. If I could locate the TCM, I would try to fashion some sort of "heat shield" to see if this might prevent the "check transmission" light. Your thoughts would be appreciated.

Is this the MH3000-4000 series?
I'd be more suspect of a disturbance to the wiring loom, or a connector creeping somewhere. Finding an intermittent one can be challenging at best.

Good luck.

Thanks, Mtn Trek. The tranny is a 3000. I understand your comments. I did finally find the TCM. I still may try to protect it somewhat from the road heat just to see if it will make a difference. It is located just above the Left rear air bag. Thanks, again........Rockaway
