2020 intermittent transmission noise at idle or low speeds

[deevilla7]

I have 20' TRD PRO @ 18k miles. Not sure this is considered normal or not.

I have an undercarriage intermittent chirping/squealing noise after 5+ mins drives.
It's most noticeable in the garage where sound bounces off of the walls.

The noise happens as I am pulling into the driveway/garage at a very low speed.
And the noise happens when in drive or reverse at a complete stop with my foot on the brake.
The noise goes away as soon as I put it in park or neutral. (VIDEO)

Soon as I turn it off and back on, the noise is gone. No noise during cold start in the morning either.

My guess is transmission because it will stop during N or P?

Thanks in advance.

Found where the noise was coming from.

The exhaust pipe rattles or shakes when transmission seems to be in drive or engaged, I am not sure where they are making contact but I held the spring portion while my wife was shifting to D to N to D, noise seems to not happen.

The weather being 95 F constantly in California is also seems to making things worse. During the night time when it's 80 F, noise happens for brief second, which I think it's the normal procedure.

bump... Did you find a solution to the exhaust rattle? Did you take it into the dealership since you are warranty?

Sorry for super late reply. I didn't take it to the dealer because I honestly think it's normal behavior with a factor of hot weather (95F+ summer).

I did tighten the spring bolts to whatever I can and just haven't heard it since. Plus weather is cooler now too.
