| Transmission was slipping up to 31%. I just got back from getting the trans rebuilt down south (22 hour ordeal). I had the allison trans rebuilt to a stage 4 with suncoast 1057 converter.I also upgraded the stock pan to a larger stock pan from the (meduim duty trucks) it looks the same but holds aprox 4 to 5 quarts extra. It was only $65.00. I found one problem on the TCM wiring from the Banks kit I had installed, this wire had a short in it and was saying the converter was locked up when it wasn't, and it was giving the truck a couple of wierd codes that we got figured out after taliking to a Allison rep.The transmission works realy good. Now about 3/4 of the way back home the truck again starts to cut out, and throws a Over boost code P0234. I was driving about 75 with only about 6lbs of boost on a flat road. I have no motor mods to increase boost. Only juice, A2 monitor, and banks 4" exhaust. |
