well i been tuning the car for awhile and never noticed this when TM was disabled. ive been trying some new things and noticed this

well i loaded the stock tune wondering if the tranny was hurt..

logged it and got this


goes 6-5-4-3 goes 35* to -12.5* of timing i sure that along with the gear hunting is causes that feel of falling on its face and not know what to do im getting so like i said its just in the tuning not the tranny it seems

like i said that log is a 100% stock tune

Yesh. I have this issue. Nearly got me hammered by an 18 wheeler getting on I-45 during rush hour when instead of accelerating, fell flat on its face. Can the dealer fix that?

I am afraid of a major failure and refusal of warranty if I tune... My GM Area rep has warned me of this a few times so far.

Good to hear you really do not have a problem

Depends on if your TCM has been updated... Mine still does this and it was built after the TCM update. But from what I understand it is not as bad as the early early 09's and all the 08's.

Mine is also after the update which is why I haven't taken it in. I think it's a safety hazard. I am going to get a tcm tune to fix mine.
