Haas VF-1 Transmission Overflow Question

[CNCErnie]

I purchased a used Haas VF-1 and just changed transmission fluid. I noticed that the overflow next to the drain plug does not have a plug in it. Should it have one, or not?

You may have answered your own question if you read it again. It's an overflow, would you plug it?

You fill until it overflows and then stop filling if I remember correctly.

Normally, I would not plug an overflow. But I was confused because it was threaded for a pipe plug. I didn't know what to think!!!

Could it be threaded for a breather of some sort? I don't have a transmission on mine so am no help beyond that.

Normally I would plug an overflow port, with a breather plug to keep dirt out.

Something like this:

Breather vents for gear cases, breather plugs and filters

The drain plug sits almost flush with the tank itself. The over flow tube sticks down a little and the tube is trimmed at an angle. To answer the original question; no, you do not plug the overflow tube. It is as Machineit said, fill until it comes out the overflow tube then stop. That simple.
