Anyone in the DFW area with a scanner? I'm getting some random ECU errors stating "malfunction in transmission" followed by the car locking itself into 3rd. I have to pull over, turn off car for a few minutes and start again. From there, error lights go away and car drives normal.

There are some hard shifts occuring as well, almost like it slips out of gear while driving. Its completely random, I am not able to reproduce on demand, and some times I'll drive for 30 mins - 1 hour and not have any issue with the tranny, other times it'll pop and error light within 2 minutes of driving.

My CPO just expired so I don't want to pay the dealer a shit ton just to read the stored ECU codes.
