OK i've been reading thru some pre-runner sites and what not and am putting some things together. What i'm looking at doing is getting a stronger C4 behind my '97 4.0 vs. the weak 5R55E, My question is how do you wire this? I know a C5 and a C4 are internally interchangable for most things. I am just wondering how the factory computer takes this or do you have to get a computer from a truck with a manual tranny? thanks guys
