I searched and skimmed over a few things but still wanted to ask. I have a 96 gt and had found a 99 gt motor with 34k for $800. I know there are certain bits and pieces that need to be swapped between motors but with the 96-98 4r70w it bolt right up to the 99 gt motor right? just wasnt sure if the 99+ autos were different. Also with the swap will the computer need to be changed? I have sniper tuning software(special force) but not sure if it allows the motor change.
