Allison 6sp: Codes

[eagleford hauler]

I have a 06 lbz with 300,000 miles on it. I just installed a new cp3, (because the original just went out), New injectors (8) these were original also, new garett turbo replacing the original, new banks intercooler, new mishimoto radiator (all heliarced aluminum). The motor runs better than when it was new, but now I am getting 3 codes (843,877,&751). I have checked all the wires and pins and can not find anything wrong!! I have not installed the drive shaft and tried to drive it yet does anyone have a clue what the trans computer decided to go whacky about? I also changed the trans fluid and both filters.

Those are valve body codes. Chances are you are low on fluid.

That is what I am thinking also because I only put in 8 qts. and I have not moved the truck yet. I am putting on the drive shaft in the mourning. Also with the radiator trans cooling area also not having a lot of fluid I am thinking this is why the pressure sensor codes are coming up. I took great care with the many wires when doing the work treating them like fragile glass hoping not to damage any of them. You guys are great have not been with yall long but already have picked up a lot of great knowledge!!!!

Did you reprogram for all the new injector flow rates also?

 

[eagleford hauler]

Yes, I did reprogram the injector flow rates. The motor is running better and stronger than I remember it running new. I deliver oil field frieght and that is basicly all the miles this truck has on it, hauling mostly with a 40 ft. gooseneck trailer. Been a great truck and has lasted a lot longer than many of my fellow haulers with Dodges or Fords!!!!!:thumb:
