[QUOTE="Dirtclod, post: 1479919, member: 20061"] Pardon me for my ignorance because I am by any means an auto mechanic, but what I've often wondered and about is why can't transmissions interchange in these trucks? One thing I do understand is the computer system for whatever reason won't allow the 6 speed auto in the newer trucks to operate. I asked this question once before and was given an explanation by someone either here in this site or another forum as to why this won't work. But however, why can't an aftermarket 6 speed be made to work in these trucks with proper tuning or even a whole new computer program base to work off of? I've always said that if you could get this linked up I don't think anything could out perform it in its class. Interchangeability has been easy let's say with GM cars and trucks. Same tranny goes behind a 4.3,5.0,5.7 6 speeds out of Corvettes will fit behind a5.3 in a s10 pickup. So is it that Ford has done this on purpose? Just crazy questions that sometimes I wonder about.
