what do you mean by "dont shift your tranny, it will kill it". I surely hope you arent talking about upshifting, because that wont do ANY damage. Its the downshifting that will take a toll on the tranny. I've been to a few tranny shops, and have asked a few guys working there what they thought about shifting through the gears and they said the same thing. downshifting is bad, and unneccessary.
