P0730 code today

Just had an oil change yesterday at the dealer. Drove home, my wife drove the car this morning and CEL came on. I put my code reader on when I picked her up at the dealership, and P0730 read out. Seems it means incorrect gear ratio. I am waiting for the dealer to tell me what is going on and the fix. I will advise. Anybody else get this code or have transmission issues?

Car is just under 15K in miles. Hope it's a software issue, not a new transmission.

Re: P0730 code today

Here is the update. Seems the transmission missed a gear downshifting. Perhaps not a gear, but it "missed a downshift," according to the service advisor. That caused a fault code. They did a flash update (software) and that's the fix. I did not drive it, but my wife said she has noticed that it is shifting better now. I always thought it held the low gear too long during heavy acceleration, like a turbo lag. Maybe this is a fix if you experience the same.
