I have read , many times, the posts on the 4200 and have some 4L60 related questions. I have a 2002 motor and trans combo, but still has the 4wd transfer case attached to the rear of the trans. I am wanting to run the auto as it will be a daily driver with low boost turbo. My question is can this particular trans just have the 2wd tailshaft/tailhousing swapped and be a viable trans? You guys athat are running teh auto, what have you done? Any suggestions on basic upgrades to make it last behind this motor. What controllers are you using? Looking forward to your input.
