Hey guys! i have an 07 5.9 cummins with the not so good automatic. i was just wondering how everyone is liking or not liking the new six speed auto.? I haven't really heard anything about it! cuz I was thinking about possibly replacing the junk 3 speed with a 6 speed if it's even possible. but then if i did that, would i have to use a computer out of an 07.5-08? then that probably wouldn't even work with the 5.9 motor, would it? You guys know what I'm getting at. Hope to get some answers! thanks!!
