Photo 1; filler plug is on the top right. Bottom left look like the hydraulic hose connection for the hydraulic clutch.
Photo 2; On my old Softail, there was a single plug was between the two shocks. In your photo it would be the bottom one. Is that a stock tranny or aftermarket?
I checked the bolt that you marked, it is just a bolt, its not a drain plug.
so what do you think are the 3 bolts at the bottom?
its an Ultima transmission.
your thoughts?...

The drain would be in the right side bearing support (aka trap door), just below the clutch throwout cover, center.
Keep in mind, I`m talking about an OEM transmission case and trap door.
The studs and nuts circled in blue look to be for the transmission mounting plate. Not drains.
The 1/8" pipe thread plug that has the red arrow with the question mark pointing at it is the drain in my opinion.
The first pic in your latest post does not look like a drain plug to me.
If it is it's the worst placement and the worst design for a drain plug since there is no way a wrench or socket can remove/install it.
To have to remove a shock to drain the transmission oil would be an insane design unless that is not the original transmission for the bike.
Put your drain pan under the 1/8" pipe threaded plug and remove it. You should strike oil.
By removing that plug, if you don't start draining transmission oil, then I am wrong and I apologize. Or maybe the trans is empty...
Put it back in and best of luck but there are a whole lot of trap door type transmission cases that have their drain plug right there.
Thanks for your detailed reply.
The studs and nuts circled in blue are smaller than the holes in the mounting plate, they are located at the transmission bottom and not connected to the plate. They look like they do some kind of adjustment because you can twist the center stud and secure it with the nut (same as you adjust your clutch plate against the pushing rod). I really don't know what it there to adjust in a transmission...
I will check again the draining. But I will also drill the plug that I found (located above the shock. Looking closely, it is a hand-cut bolt, I will take it out and see what it does.
Thank again!
Since you bike is a custom and I have no idea where the components came from I am giving you my best guess.
Bummer you have to pull a shock to get to that piece.
If you have a set of reverse twist drill bits that may make pulling that thing out of there much easier since there is a chance the bit will grab it enough to unscrew it.
Easy Outs (AKA bolt extractors) are a PITA in my experience.
The "adjusting" screws on the bottom of the trans are new to me. Like you, I can't imagine what they would adjust inside or outside of the transmission.
Unless...your engine and transmission are rubber mounted. And I still can't think of what they might do.
I have not seen a Softail frame that has a rubber mounted engine/trans combo.
Is that what you have?
