Camry 2012+ :: Cold Shifts Are Getting Harder As The Mileage Of Vehicle Increases

I have a 2012 with 5k miles. Starting near 3500 miles, the car started doing hard shifts when 'cold', e.g., when started after sitting overnight. As the engine warms over the first few miles, the shifting smooths out.

The shift behavior also occasionally presents when the engine compartment cools during normal driving. E.g., if I drive several miles at 45mph on a cool day, the airflow under the hood allows more cooling than when stopped at a light.

The cold shifts are getting harder as the mileage of the vehicle increases. Changing from 'D' to 'S' does not work for the problem.

After several rounds with the dealer, they connected me with a Toyota regional representative. He and I drove my car, along with several other 2012's on the dealer's lot, each with a different odometer reading from 2k to 10k. I have also driven a 2012 owned by my parents, that has 2k miles. The conclusion he and I both reached is that the 2012's have a common cold-shift problem that starts around 3k-4k miles, and worsens with mileage. The highest mileage car I drove (an XLE) had 10k miles, and its cold-start shift performance was terrible.

After a month, I'm still waiting to hear from Toyota about what they plan to do (if anything). What was the resolution?
