Culver Automotive attributed the reason my car wasn't going into overdrive, to needing a new transmission. Turns out, all I needed was a new over-drive sensor which I learned after picking the vehicle up, and it still not going into over-drive. I called Dimitri, the owner, right away and he told me to bring it back in. He replaced the sensor for free, but I was still out nearly $3,000. for the transmission and the other work unnecessarily done.
So, definitley get a second opinion... especially if you're a female!
