c6 running bad has lots of codes
Hi Guys
Could use some help diagnosing our 2011 C6 automatic 4LT Convertible 30,000 miles
Dash warning lights on are Brakes, ABS and a orange light on the left side of dash that looks like a car and a master lock combination
Transmission feels like it starts off in 2nd or 3rd gear sometimes, shifts are erratic at best. Very rough and herkie Jerky
Display says car is limited to 80 mph
After doing a small amount of research I orders a GM 12369458 Module Speed sensor. Diagram showed Module to be located up behind the right rear tire on top of the transmission. Was not able to locate the module where the diagram showed it to be
Codes are,

Clear ALL the DTC's and then see what comes back...what kind of electrical diagnostic experience do you have ??...not a good idea to change parts based on a DTC...if this testing might be over your head an auto electric shop should be your next step...no silver bullet repair here unfortunately !!...you have a few communication codes and 99.99% of shops or dealerships won’t know where to start.

Hi
I swapped the battery out of the corvette that is about 1 year old and installed a battery that is about 6 months old from our Equinox .
Same problems with the corvette
Thanks for your suggestion. I know that the newer cars are very sensitive to having the correct voltage from the battery

Hi
We`ve owned the Corvette for about 11 years. The car had about 11,000 miles on it when we bought it and haven't noticed any modifications on the Vette. So I wouldn't think car would have an aftermarket throttle controller on it
Thanks
