Ok so I was testing a theory today, basically to see if I would be able to put my truck on the dyno if I had overdrive locked out and in tow/haul. So I was driving and switched to my 500+ competition tune. Got to about 40mph and stomped it, it got to about 80 and limped. At this point i pulled over checked and cleared the codes, and it drives normal. I've limped it before, but its always been when it shifts into 5th when hard in the throttle. I have every intention of building it, but I just want to know what caused this code, is it that my clutches are worn and the solenoid couldn't put out enough pressure to keep it from slipping? Thanks for any help

When it comes to questions about the Allison Transmissions and what makes them go bump in the night you need to call Mike Loveridge direct at Inglewood Transmissions or drop him a question on his forum site here. Mike Knows Allisons. He built mine and it has never failed me or as you have experienced "Limped" since built. :cool2:
