As with most fill ports on the side of any automotive or machinery gearbox, that will be the maximum you can fill if the plug is removed, even if you fill from the top. That would be the recommended fill level.

Sounds like a plan man...Thanks Fierofool. I'll let you know if I find one on the 86...

Manual transmission oil doesn't use a weight / viscosity designation. Like mentioned before, just look for GM or Pennzoil Synchromesh, or Royal Purple Synchromax.

Careful...
There were at least two, maybe three versions of Getrag case. The earliest ones (I could be wrong on this) were filled and checked through the VSS hole.
There was a later version that had a fill plug in the back side of the gear case. It faced the trunk wall. Screwed in at an angle, from above.
The latest version has a real dipstick, with a plastic flip tab to latch it into place. THAT dipstick is in the drivers side of the differential housing, and is inserted straight down into the case.

I'm not sure when my 86 was made. The tag has faded but I seem to remember that once I checked and it was in made in May. Number 281921. The transmission has the plug on the side and it's about level with where the markings would be if on the VSS. It also has a screw-in dipstick.

My Getrag also has a screw-in dipstick. It came out of a Chevy Beretta. [This message has been edited by Blacktree (edited 05-12-2019).]

My 86 does indeed have an all metal screw in dip stick. I asked before if the level is checked with the stick screwed in or out, there's an inch difference. The 'low' and 'full' mark on the stick is only about 3/8 inch apart. This matters on some other type vehicles. I'll see if it has the 'fill-to' plug on the side. Stick in, or out, mine is overfull, but it'a been like that for a long time...I just want it right...My service manuals (Pontiac, Clymer, Hayns) are all different when it comes to this matter. If I remember right they all mention pulling the VSS out...No mention of the stick...

Different capacities charts vary, too. Anywhere from 2 quarts to 2.7 quarts. Minor overfills on the manual transmission probably wouldn't have any serious effect compared to overfilling an automatic or an engine since there's no blow-by or extremely high temperatures generated. There is a small breather port on top of the transmission, and if it's functioning, no pressure should build up inside the transmission.

This one is major over-full. Almost 2 inches on the stick. It's been running like that for quite a while, so I agree with you that it shouldn't matter that much in the manual transmission with the vent/breather, but this is too much any way you look at it. The car won't go out again till it's right...
