Last night I finished installing the powermax turbo on my 6.0 and was out on a test drive. Everything was going great and the truck was running better than ever and I had power to spare. Then disaster struck. It has a ZF6 tranny in it. I was going up a small overpass incline and it sounded like all the splines on the input shaft just ripped off. the most awful noise I have ever heard from a truck. I pulled over took it out of gear and the tranny was still trying to turn in neutral. I don't know that much about these transmissions but i do know that is not normal. I drove about another 300 yards and the transmission locked up and it is dead now, I am currently looking for a new one now, but here is my concern. Is it possible to have too much horsepower at the engine for the zf6 to handle? I don't think the power has increased that much over stock, maybe 30-40% or so if I had to guess.
Has anyone experienced anything like this in the past? If so any knowledge would be a great big help.
