Technical auto trans

on auto trans dipsticks it says to not overfill, but what happens if you do. how does it hurt it.

 

oil gets frothy from the rotating parts being in it, and air bubbles are not very good at holding hydraulic pressure...

and it also spits oil out the fill tube and catches the car on fire when it hits the exhaust

 

& If over filled wants to running temp
You can take a What we call Turkey baster , add house or suction
gun / tube to & suck out ,
Most domestic train add/ full are in pints
