I want to go to 20lbs.no 4l60e will hold that power.RPM recommended I go with the TH400,but I have changed my mind! i am going with a 6 speed instead. With a 6 speed it will make even more power and i will have more fun with it.It is a Viper spec 6 speed also,so it will hold the power.
Sorry for some reason I thought it was stock my bad. You can always go to a 4l80 and it won't break. I don't think you could make enough power even on full boost to tear it up. Just something you should think about.
