subscribed to hopefully read more info on the car...

good luck with finding a reputable transmission shop - sounds like an uphill battle to me...

would you care to post more on your car/engine?

according to about six year old GMPP info the L61 saw boost leak and possible head flex at 8psi - so info on your build would make for a great read!

maybe if you guys would pay attention, we were only giving him **** (or at least i was anyways) because he posted a thread earlier saying 350 to the wheels and this one pops up at 375.
if he built his car then fantastic! thats great crank some power out of the bitch! but how the hell do you have your car built and not know what it pushes?
not to mention how many threads do you need to ask the same question?
ive been giving him **** about it and have told him to goto the local shops four times now, so since im doing both does that mean i goto ******* purgatory?
hm?
I haven't come back to the thread.

Powell raceshop would be a good starting point, they've gone pretty far on cobalts. ZZP also has pretty strong automatics they use in the GTP's, so i'd ask them as well.

There, better?

The point of my post, since it was obviously missed by you, is that this website is full of naysayers and **** talkers, and then they wonder why nobody wants to help them.

I've dealt with it, people denying what you do, even though they have no basis for thier bullshit.

I've built cars that never see a dyno. Who cares about dyno numbers? I don't need to stroke my ego with a sheet of paper, i'd rather see the car compete and win against other cars, that means a whole lot more to me than a dyno number.

Go away

Any chance your shop took it out and romped on it and broke it themselves? Did you just get this done? From the vid you say it happened right after picking it up from the shop. Unless you were having issues before or you beat the **** out of it as soon as you got in it I think they might have something to do with it.

Well the shop has 1500 hp mustangs and old cars so a 350 hp cobalt is nothing to them, they do road test it but they dont beat on it. I had it turboed last year same tranny, so that could be the prob
