I will be installing it shortly. Will be running an f150 coyote with the matching 6R80 and built up D20. Unless you're doing a coyote, I think this tranny is a bit over kill. Id go 4R70W. Im assuming Tumblin designed this to give you the best possible partner to the coyote, and now that the stand alone 6R80 controller is available, this setup will be more popular.
