    4L60E swap

    I'm taking the turbo 400 out and installing a 4L60E. The car is currently opererating on the original 99 manual computer. Is there any advantage to running a newer auto computer or just use a 99 ? Thanks for any help.

    i doubt the manual computer will have the shift points for the auto tranny. IMO ur best bet is to just find a computer that is tuned for your engine/tranny setup and install it.
