Sounds like a good plan. I've wondered if the shift kit by itself would keep the transmission together with the turbo over the long haul. It seems so random as to who has transmission trouble and who doesn't.

I don't think it's random at all. I think some of us don't beat the **** out of our cars, and when we drive them hard, we know what hurts them and what doesn't. Those of us that take care of our cars don't consistantly do things to them that we know will hurt them. If you look at the literally millions of W bodies that are on the road, I guarantee you the percentage of people that have had serious problems with the 4T65E-HD is low. Of course, when people have problems they're going to bitch about it, as they should, but it makes it "appear" to people that the problems are more common than they are. My 97' GTP has 137k miles on it, it turns 13 years old tomorrow as a matter of fact, and it has been run hard it's whole life. I've done nothing but drop the pan and replace the filter it's whole life, and it's been driven hard (but not abused). I had no issues with my 95' GT (with B4U package), and I had no issues with my 04' CompG, and so far no issues with my 08' GXP.

My tuner said that at 6psi I was pushing limit of what the 4T65-HD could handle. However the 1-2 shift is a little slow from time to time. I thinking it maybe on the way out? On a side note only running 6psi sucks, there is so much potential, and boost controller is right there. (must not push the button, the beautiful shinny button, the jolly candy like button)

I've dropped the pan twice, cleaned the gunk off the magnet and the bottom of the pan, replaced the filter, and filled it back up with fluid. I am one of those that prescribe to the theory that the flush is hard on the valve body, loosens up stuff that's attached to surfaces inside the tranny, and puts that crap in solution in the fluid that wasn't in solution before the flush. Plus, I feel that adding all brand new aggressive fluid is hard on elastomer seals, etc. By not flushing, you're leaving a small amount of the old fluid to mix with the new fluid and it's not as big of a shock on the seals.
In my 32 years of driving/owning cars, I've only had one transmission fail on me and it was a 94' Chrysler Concorde FWD tranny. I must be doing something right.

I was more thinking along the lines of it seems random as to which mods/driving styles are hard on the transmission. If Bryan is running 6 lbs. of boost without issues at 50k, then why are people with a CAI having trouble at 20k? I think I may have found the answer in that other thread though, and it seems to be a bad combination of a little extra HP and the stock tune.
