    Has anybody swapped in a 4L80E???? I know this tranny is really strong and i heard that it is 32 spline. i have a TH400/203 combo, so i figured this would be the best swap. what do you guys think??

    I have not done one but there has been posts on here about it. If your going to run the NP203 tcase you will need a adapter plate from advanced adapters. Also you will need a stand alone computer for the tranny. If you do a search there was a big thread in one of them telling you what you would need for the swap.

    I am doing the same.
    I have just rounded up all the parts to do this swap.
    I will be running a 4l80e, 203 range box, doubler, 205.
    Dont waste your money at A/A, ORD can tap your 203 to bolt behind your 4l80e.

    Good luck & let me know how yours turns out.
