2012 4.6 Sealed Transmission Question

[Chad Keller]

I just bought a 2012 that was completely under water for a few days. I know the transmission is a sealed unit but I figure there has to be a vent hole somewhere on it. Does anyone know if this unit is completely sealed or if it has a hole somewhere to vent where water could have gotten into it? I am cutting this car apart to repair two others and don't want to throw out the tranny if it is most likely ok.

It's "sealed" in the sense that I don't think there is a vent hole. There is a fill plug on the left side towards the rear of it, then there is a level plug and drain plug on the bottom of the pan. On that note, I would drain the fluid and see if any water comes out. Water will separate and make its way to the bottom, so it should be on of the first things you see.

You will have to change the fluid and filter for sure because of a chance of contamination. The tranny is not air tight.
