Not that this is anything new to this board but a few weeks back I installed a Transgo TFOD shift kit with seals and a TCS Super Duty Converter in my 2001. 5 3500 ( 30k miles). I also installed the usual performance toys. Well just got back from 4,500 mile trip pulling my 25' travel trailer, and all the stuff that one takes on a vacation, and was rather surprised at how well the new upgrades performed. I'm most impressed with the results of the transmission and converter upgrade. I was a little skeptical about buying a milled stator converter, but have since overcome that skepticism with how well things have worked out. Knowing that I have less then 450 bucks in the trans upgrade even makes it that much better. Know I enjoy driving my auto almost as much my old 5spd. DBR
