2021 Toyota Camry Power Train

2021 Camry, original owner. Maintained through lot through Toyota Care, whining noise began at 67k miles, after 3-4 years of ownership.(with in timeframe, but outside of 60k warranty) Toyota Vacaville quoted 12k for total transmission replacement.

My 2021 Toyota Camry Se at 79,000 miles threw a PO705 code, neutral safety switch. I replaced it with a new part and it worked for about 10 minutes and then proceeded to throw code again and slip in the transmission

Was driving in a FastTrack/commuter lane on the Interstate at 65MPH, all of a sudden my car would not accelerate forward. It coasted a bit. I was able to stop between the Fastrack lane and an exit space, in the triangular median. I easily could have gotten hit, especially if I had been where there was no painted median I decided to walk behind the sand filled garbage cans that were infrint of the guardrail. I feared people might miss their exit and kill me. Behind those cans seemed safer. I was told by Toyota Dealer my transmission needs replacement. It's covered under manufacture warrenty. I bought car in August 2021 new from dealer.it has 51808 miles.

The transmission on this vehicle has a delayed shifting between 1st and 2nd gears when accelerating. I am concerned that there is a transmission issue happening.
