Ok..so I asked this on another forum but figured knowledge is a good place to start with this.
My Allison has started to act up with a Tran's Code of (D-1) 00-35, which translates to a "power interruption", (D-2 thru 5 had no codes). Went on a 300+ mile trip where while at highway speeds, the "do not shift light " will come on and the shift pad will go blank and/or have two figures in the display that look like small "t's". On this trip it did this about 15+ times. On the way back from this trip it didn't do this at all other than on initial start up and when I got home and put the MH in reverse....in this case it felt as though when the tran's was in the do not shift mode while backing, it actually came out of reverse...I thought I had run into something.
One other tid bit of info, at highway speeds when the do not shift indicator came on, the speedometer went to zero and when returning to normal within seconds, I would be right back into the same gear. My odometer/trip odometer stopped working about the same time as this all started.
Any thoughts? I will pull the ECM and display wire harness's to clean with contact cleaner but after that I'll be a loss.
