M6 Throttle Response Issue.
I own a 2011 2LS automatic w/paddle shift i understand my car when i put it in manual starts in 6th gear on my HUD and for the first year it had a great response to it i know the LS doesn't have a sport mode like the LT's do as far as i can tell. Recently my throttle and shift response in M6 has been terrible it over revs to 5rpm alot and isn't shifting up in gears like it used to and stays at 3rpm and holds there when braking sometimes. I have little knowledge as to what could cause this sudden illness to my camaro if anyone else might know i'd really appreciate the help. Please note that when it's in drive everything works just fine.
