    I know it will bolt right in but being the truck is a 91 cc chevy with a TBI 350 the computer is tied into the tranny do you have to do anything special to the computer to make it work. I know about the switch for the down shift on the 400 tran got that handled.. /forums/images/graemlins/crewcab.gif /forums/images/graemlins/k5.gif /forums/images/graemlins/ears.gif

    why would you want to go from a 4l80e to a th400? /forums/images/graemlins/dunno.gif
    you could get a computer from a 90, or some thing that has a 700r4
    im not 100% sure but i think the computer changes some setting on the motor after it is in gear, so just running it any way might do something.

    not exactly sure on this one, most people go the other way /forums/images/graemlins/dunno.gif /forums/images/graemlins/dunno.gif /forums/images/graemlins/dunno.gif
