So is there just one setting that you set it too and its set to a certain pressure or do you have to spend countless hours tuning it to the pressure you think is best? Cause I hate mods like that!

That wouldn't be for you, bud. You have an electronic trans, not a hydraulic. If it is playing with it forever, that would be AWESOME! I'd love to have that kind of control.. but from the looks of it, it looks like it'* vacuum operated, and it doesn't look very cool. Nor does it really look like it'* worth $50.

I beleive it is possible. I was looking at the FSM recently, and i think by "adjusting" some key information thats sent to the transmission you could help it out a little bit, but i dont remember exactly what needs to or can be changed...

BMS could a pot be used inline with one of the wires to adjust it?

I have one of those Transceptor devices and used it before installing my INTENSE shift kit.
It works very well except it does not modulate shifting pressure depending on throttle application like the INTENSE kit does.
So even when shifting with light throttle, if it is set to shift hard, the trani bangs into gears......very hard and annoying.
I used to have it turned way down to almost stock shifting and only turned it up when I wanted to play.

I found another tranny option today, http://www.importperformancetrans.com/gmautofwd.shtml
I don't know anyone that has a tranny from them or even if they put one together yet but it'* another option to investigate.

so thats basically like a performance tranny for the NA guys? could a 4T65E-HD fit to a L36 engine if that engine was producing the same amount of torque and hp (if not more) than a L67 engine?
