I would suggest not to do it while the vehicle is under warranty since it might void your warranty.

Just use it and if it breaks you are covered.

Alrighty closing out the loop of my issue, and short version is they made a software update, cleared the codes and tested. They kept it 2 days and put about 30mi on it and never triggered the issue again so I picked it up today.

Far reach from replacing the transmission but if that’s all it was and it never happens again I’ll be happy. Felt normal driving home so fingers crossed it was just a bug.
Hey there - have you experienced any other issues since you picked up the car?

I just had the same thing happen to me with the same 3 errors. However, I did hear a loud thunk noise and the car went into limp mode. Dealer cleared codes and haven't been able to reproduce it after a short test drive so they are asking me to pick it up and keep an eye on it.

Thankfully have not had anything happen since, working perfectly and I just crossed 5k miles!

sorry you had that happen, I know it’s a terrible feeling but hoping yours turns out the same

Is transmission oil temperature an indicator of this problem?

Codes pulled for mine were transmission related to "pressure control solenoid actuator stuck". Don't know if its a fluke or if its bound to happen again. Only 500 miles on the car.

I have a 26 Platinum with a 12/25 build date and currently at 1000 miles. Fingers crossed Toyota resolved the issue by then.

I've experienced, for lack of better explanation, not smooth shifting at low speeds, when coming to a stop. Also, some not so smooth shifting accelerating from a stop, but not jarring.

This is my first hybrid so I assumed it was just hybrid vehicle behavior but this thread has me worried.

I'm at 6k miles on TRD Pro and no issues so far. Knock on wood.
You shouldn’t have any issues. I wouldn’t worry. I’m in a Pro as well. And my Hybrid speaker under my back bumper went out. Toyota replaced it under warranty.
