Went to Sacramento to race with my new turbo this weekend and was happy/mad... ran my same old times with a brand new turbo to start with cause tranny is shifting weird, so after a few passes, disconnected battery and reset comp... then got the truck to run 14.89ET (.11) faster than my best time... but the tranny still shifts weird.. heres what it does...

I charge up my turbo, leaving at 20 lbs seemed to be the best, and let her rip when the lights go... the 1-2 shift is perfect, then the rest of the shifts are phucked up... it runs normal till about 3k rpm, then goes into free rev for a split second, maybe a whole second and then shifts, does that threw all gears... by that i mean it revs slow to 3k, shoots up to 3,300-3500 rpm (red line) and then shifts, im losing a lot of time and power there... any idea what this might be?

-Thanks, Dan

You have balls....

Sounds like the tranny needs a rebuild and a good VB.
