Default Hiss of air when removing inner shifter boot

Gents,

I'm doing a shifter rebuild on an early NB six-speed. When I loosened the first bolt on the inner boot, I heard a hiss of air that lasted a couple of seconds. The vent (I assume it's the vent at the top of the trans in front of the shifter turret) cover is clean and jiggles. I also assume it's clogged. Any suggestions short of taking out the transmission would be greatly appreciated.

Thanks,

It's not a normal issue for most of us. Might be a fluke.
I'd leave the console off and drive car around a couple of days to see if it re-pressurized.
If it does please post again.

You might have a gremlin...

Why do you think it is pressure? Why not vac?

I propose the vent is weighted, and if so parking a hot car will naturally create a vac inside the transmission. Or at least any that aren't my drippy piece of six...

I never said one way or the other, but would have assumed vac as the transmission cooled with a clogged vent. I searched for six-speed pics and it's not obvious (to me, anyway) how maintenance is done on the vent.
