    Hard downshifting

    Yes i have considered that but who? the dealership? I don't want to bring it to a dealer and there are no knowledgable diesel shops around that have done work on duramax trucks let alone allison transmissions... And it's a suncoast gmax kit

    Hard downshifting

    Hard downshifting

    Yea i understand the problem is getting my hands on one which i will try to tomorrow. Is there a possibility something is sticking in the valve body or something because there was some metal and some plastic sent through the trans when the clutch pack went? It was thoroughly cleaned but still

    Hard downshifting

On the way to work i got alittle more than halfway there and it started acting up again, It kept throwing the engine light same code (700) and then it started to slip from 1-2 and 3-4.

    Major allison problems..what do you think?

    The confusion was a mistake of the plates it looked as if they wanted you to reuse the stock one. It has about 6k on it and i put it through its paces but i dont thrash on the thing. Not much power just a nasty EFI tune with supporting mods. And when it happened i was slowing towards a...
