Changing the fluid and filter in the transmission (10L80) in my 2018 Escalade. I’m using the hole in the first picture to fill. When the fluid starts overflowing from that hole I assume I should also see some drips from the check hole in the second picture. However, nothing is dripping out of the check hole. The vehicle is level and the temp is 170 degrees. If it’s overflowing the fill hole in the first picture do I just call it good even if nothing is dripping from the check hole?
