Dust cover for 5 speed

There would be a small window cutout if that's what you mean.
I would think its towards the bottom of the transmission.
It's there for air pressure to escape.
Think about it, you have that flywheel spinning pretty fast and if that section between engine and trans was fully sealed up you would have a balloon ready to pop.
Post up a picture of what you're talking about.

Ok that looks rather large.

Reading this thread people are saying there is supposed to be something there.

Maybe it's this Gusset thing they have in the factory service manual?

I'll crawl under mine and see if there is anything.
Off the top of my head I know my subaru has like a 2 inch by 2 inch window cutout at the bottom of the trans to let out air/water.
I don't remember what it is at the bottom of my nissan. Even on my automatic I do remember there being some kind of black plate.
Might wanna dig around for some diagrams or something, that way you can get a part number.
Someone who parts these cars out will have it.
