Headers, CAI, Intake and TB.......CODES
We installed the following
TSP headers
AFE CAI
BER ported intake and TB
Tuned the car. DID NOT touch the trans tune. Now I have an overwhelming number of P drivetrain codes. I have checked connections and all seems to be in order. Any help is appreciated.

Same thought here. I have been trying to find a diagram of the C7 ground points but am not having luck. Don't know what I could have pulled lose doing headers and air box

First thing is you need to confirm the battery is good. Low voltage on start up will trip all kinds of codes.
During start up, voltage will drop for a few seconds as starter pulls a lot of juice. A good battery will quickly recover. Watch ammeter. It should stay above 12 volts. Check battery before start up. A good battery will be between 12.5 to 12.7 volts when not running.

Thank you. Car has 4800 miles on it. Hopefully the battery is good to go. If not then we have some crappy batteries in these things

I did not notice I did not see an engine ground loop on each side of the motor like on C5/6 cars. That would have had to come lose when I pulled headers. Also if it was a ground then I believe I would get codes other than transmission

grounds are behind the airbox on the inner fender and think also on the drivers side similar place. Did you do full exhaust or just headers? those trans codes indicate either a ground or power issue or something unhooked back at the trans.
