Got back to Atlanta after driving 500 Miles from Florida two weeks ago. Stored Coach in heated warehouse. Coach is a 02 Holiday Rambler Endeavor Cummins 330 ISC. Tried to pull coach out last Saturday but now it wonít move. I started it up and let air pressure build up. When I put it in reverse it felt like the air brakes were still on and would not
move. Code on the transmission key pad showed oL-70, sump temperature too cold. Also code is 2214 - Speed sensor. Before leaving Florida there were no codes or issues. I checked and cleaned all sensors on transmission but still no change. Called Allison and they said start it and let run for 35 minutes then go through the gears five times. That did not resolve any issues. Called two shops that service Allison and one says speed sensor will lock coach down and the other says itís brake could be causing the problem. I plan on getting underneath tomorrow with electrical tester. Has anyone else experienced this issue and how were you able to resolve it?

If you have drum brakes chances are your brake shoes are rusted to your drums. Not a problem really, use more power to force them free, sometimes reverse helps, or get a hammer and punch to force shoes to release
You’re the man jporietis! If you ever come through Atlanta let me know, dinner is on me. It rained for the last 200 miles of our trip so made sense it could be the brakes rusted to the drums, but seemed unusual since the coach had only sat for about a week but that’s what is was. I was able to break them loose and didn’t even crash through the wall, happy day! Thanks all for your rapid responses to my post!
