Most power put down thru a 4l60e
Mine has lasted 150 or so passes on the old setup below, not a hiccup, still running good. (knock on wood)
Now though I am only a few weeks away from getting the new setup on the road and I doubt she will last too much longer.
I've built the motor and will be running a front mount 76mm
I want to be around 700rw right away, just wanting to see if there are any others out there that made it past 600 on a stock tranny

and I was reving to 6900
, most of the guys on the GTO board say my tranny was built by god...
I have been pretty damn lucky. I doubt I can go much further though, although I sure will try.So judging by the response there are not too many stock auto's going big...

I know "Twofast4lv" Ellis is putting 602rwhp down all last year. "WAHUSKER" is making 620+ for two seasons and "Ryan K" (Fueling and injection MOD) has been running his at 650+ rwhp last year. Ryan is having his whole set up redone with bigger turbo and piping and expects 800RWHP this time around....We're wondering if the tranny will hold that and for how long? "CHarris" probably has the most load on take off with his 402 powered Hummer (AFR heads, headers and Kenny Bell running at 9 PSI, soon to be 12PSI) and so far no problems launching at 3500rpms with that 6800Lbs race weight...
Oops. Just realized you said stock tranny....Good luck with that...keep us posted...
That being said I have a 4L80 being built right to prepare for the future (FI).
will find out how long it lasts
