Hey all, new to the forums and still studying the Duramax engine/tranny. Do have a couple of questions, though. I was told that the Allison tranny can hold roughly 380hp b4 the stock torque converter starts to separate? True, or not even close? Also, who makes good turbo upgrade kits for the LLY 05? thats the model I'm looking at purchasing, so I'm trying to learn as much as I can so that when I do get it I can do alot of the work myself. Oh, and don't worry, I'm an experienced mechanic.
