Dave asked if I was going to add power to my truck. (It's stock 180 h. p. ) I told him I would probably do the TST 230 h. p. first, maybe up to 300 in the future, that would probably be it. The pressure is pretty high on the transmission, which is what I need for big power. The transmission is very jerky Dave said come on back if you want to lower the pressure. I need some opinions on what to do. I would like it to shift a little smoother, would I be giving up to much in performance? I thought with a three disc TC you could get by with stock pressures. I am afraid I just don't know what I am doing, but I do know I have a heck of a transmission now! I am just curious what you guys have discovered.
