You don't need a higher stall. It'll get you lower 1/4 mile times, but it will also kill your MPG and make your car "feel" more sluggish on the street...unless of course you're stomp on it, then you'll take off like a bat outta hell! Besides, without additional cooling a high stall isn't the best thing for your transmission. I guess if you really want one it all depends on how high a stall you go with, mine is 3500 and I can't recommend it for a street car. If I could do it again I wouldn't go any higher than 3000. Just my opinion.
As for the transmission, I hate the damn thing. There are guys who are running serious power through the stock 5R55S with no problems (yet), but it's been a nightmare for me. Next time I need a rebuild I junking this POS and going with a 4R70W.

I've been driving a cj-7 for 10 yrs and my hip is due for replacement! so when I decided to hunt for a GT I liked the prospect of an AUTO.
However, I got an 06 auto with a 5s55w and after 2 weeks I wanted to drive it off the pier.
problem is the dog gone shift lag, shift when ever it wants to blues, the new dynamic since putting in a tuner is "double shifting".....and finally..... boredom.
when I bought it the dealer stated the lag is a charactoristic of the car...OK fine, I dont like it and what can I do to step it up....they recommended a reprogramming kit from transgo and $600 for the install....Done.....
3/4 pinned great responce! cruizing speed--eratic! ...... OK fine now what? BamachipsCAI/tuner.... OK fine, again 3/4 throttle ---get out of the way, cruizing same dynamic with a sprinkling of "double shifting"!.....F*#+&!!
just yesterday I got installed 4.10s.....I dont think it will effect the trans much but at least the trill of the launch will offset the disapointment of this Auto.
My wife drives an 09 626 auto and the transition between gears at ANY speed is music...
I love my GT otherwise! ...thats the problem, everything else is perfect, the size, the the looks, the power..... I wipe it down every night, its almost therapy...
I agree with the other fella, this trans does not meet my standards and I havent started yet but I'm going to look into another Trans...
in passing has anyone heard from Doug at BAMA? i've been trying to contact him for 10 days...
Aloha,
Gil
