Acceleration hesitation FIXED!!

So I bought my 07 3.5 LT in January, and quickly noted that i thought it accelerated kind of crappy when cold and at moderate acceleration. I did a TON of research and a lot of impala owners have this problem, along with a bunch of other GM cars. Most people on here said it was "normal". While it is common, it is not "normal"

Well, it ended up needing the second clutch pack and solenoid replaced. There is actually a bulletin in Alldata. When i took it to the dealer the mechanic couldnt duplicate what i was talking about. But the dealer was very helpull and offered to do the Bulletin fix anyways under warranty. Well, now it works perfect! Shifts more crisply and accelerate way quicker, no hesitation!!

Just thought i would share my story in case someone else is having this same problem.

That's great!

My '08 with 3.9 is at the dealer for the same thing, they're having trouble finding what is wrong because there are "no codes". Had to take the tech for a ride instead of paying for another injector flush that they already tried.

Would love to get any additional info, like the alldata scoop. Can you post a link or document or something I can take to my dealer?

Thanks!
