You probably have a slipping clutch band in your transmission. Take it to a transmission shop.
You need to have the transmission computer checked for codes to know possible causes.
It's not shifting into neutral, the 3rd gear "drive" band is slipping. Time for rebuild.

Your transmission could be low on fluid or your bands inside your transmission are bad and need to be replaced.
Any unnecessary shifts cause additional wear on the shift mechanism, but that's a minor consideration. At a long signal light or train crossing, it's better for the transmission to shift into neutral than to keep it in drive with foot on the brake, or if a manual, better in neutral than holding in the clutch all that time.
It may be low on fluid. If not then the bands inside the transmission are bad or gone.
A Camry transmission will experience late shifts if the fluid is low or the bands are worn. This is an early sign of failure.
My 2018 is hydrostatic and it has a small pin in the back that shifts it into neutral and will disengage the transmission to make it free wheel. Hope this helps
My f150 shifts from 2wheel to 4wheel on the fly, but to use 4low you need to be stopped with your transmission in neutral to engage the low range in my transfer case.
there is no fuse that makes the transmission shift the transmission shifts on cylinoids and rpms
