Auto trans goes to neutral while driving in D

[trupial]

hi all, i got a 2007 yaris sedan 2nz-fe automatic. and randomly while driving the car in D. it would get out of gear, kinda like going into neutral, it can rev freely for 5-10 seconds before going back into gear.

a friend used a cheap knock off scanner and we got a p0500, i checked around and found about the vehicle speed sensor.

but im having problem searching for the right one as i mostly get 1nz ones or i see 2 different looking ones online which got me lost and confused........
