G730 fill /vent plug?

[daman1]

did a service on the transaxle today and while I had the vent plug off I found that I couldn't blow through it upon inspection it looks like there's a paper washer in there preventing it from venting has anybody seen this before why would they have of then but then plug it off with this paper disk?

Perhaps it is designed to be one way, out only. You would not want it to allow to suck humid air into the transmission.

Thanks but no it's not I could not blow either way in or out that little paper disk had it completely blocked off, usually these type situations there's only pressure and if that's blocked off you could blow out axle seals.

That's why I'm wondering if anybody else has seen this while servicing their transaxle?
