Some?
Driving with it disconnected doesn't usually dump much fluid. The normal level mark on the reservoir is below the vent. The fluid level does rise some when you park though, and increases in the back there while you are accelerating. Plus driving through water risks contaminating the fluid with the vent disconnected. IIRC, the other end of that tube connects higher on the casing; it does not vent directly to atmosphere.
Best to check the level in the transmission, and add fluid as needed to restore normal level. Fluid level is checked hot with the engine running, car sits level. Your owner's manual has a picture of the reservoir and the marks on it. I use a flashlight, and a cheap makeup mirror sitting on the floor forward of the front of the gearbox a little. Much easier to read level when the front face of the reservoir is cleaned off, I've found.

if you park it for a long time AND the torque convertor leaks down the level can rise up so fluid leaks out ....makes a puddle on the ground and scares you nearly to death...the hose prevents that

Greg Brown carries a correct replacement hose.

Make sure whatever you use for a tube is compatible with automatic transmission fluid. The previous owner of my 88 S4 replaced that line, and it got soft and swollen after being exposed to ATF, which created a leak that was a bit difficult to track down. From experience, if the line is leaking, it will cause the fluid level to become low after a month or so of regular driving.
Not all vacuum line is compatible with atf.

FWIW this flex tube is rather special ,
its made of more than a few different layers of material,
its a very thick wall tubing and a small ID.
If your removing this hose the best way is to remove it from the outlet on the transmission body use some bent long needle nose pliers.
NOTE let the hose stay with the reservoir as its possible to neatly snap the hose off the tank port.
its a press on fit so no clamps are needed
