    I am in the same situation as you are, I was told by Steve (Frost) not to drive mine. I am going to trailer mine to the dyno tuner, I am also going from 3.42 to 4.10. Mine was tuned for the 3.42, but I am also highly modded with the internal engine and transmission parts. I would imagine in your case it would make the transmission shift funny, damage??? Maybe, maybe not.
