They had opne explode on the Power Tour last year. There are different torque capacities, the price is fairly high, and its only software that controls the trans shifting. They've been advertising it for about 8 months now. I know for the most part, the few buyers are happy. I dont personaly know anyone, just what I read. I dont know how well it fits, but the concept is pretty cool. I'm not enough of a fan of OD to spend that much coin on a GM part tho.
