I appreciate that I’ll let you know how goes.

I'd suspect, esp. once you have that O-Ring in your hand, it's highly likely to find an O-Ring manufacturer who produces an oil/petroleum resistant equivalent O-Ring of the same dimensions should the O-Ring you purchased appear unworthy. Oil/Petroleum resistant rubber contains Nitrile (Buna-N) I believe.

I have it now. Seems to be in ok shape except that I cannot figure out how to get this plug out!!!! It is a 3/4” head, a socket will not fit into the space, a wrench will get onto it (box end) but there is NO room to wiggle the wrench even slightly. Stuck. Any ideas?????

A 3/8" &/or 1/2" drive socket likely won't work in your tight space, they may or may not - I don't know. A 1/4" drive socket set is likely what you'd like to use along w/ a flexible extension. You likely might need to use a wrench 1st to break (loosen) the plug. Once loosened, I'd try a 1/4" flexible extension.

Great idea Norm, that didn’t even dawn on me.

I failed to mention that no 3/4” socket can fit through the gap between the flex plate and the housing. I can’t even get that size near the plug hex head. I may have to custom build a tool to get this done. That box end 3/4 wrench does fit onto the plug head, but I have zero clearance to turn the wrench.

Here's an idea.
Keep pouring trans fluid in it this summer and enjoy the car.
Pull the trans out as a winter project.
Change the trans valve O rings if you wish.
But replace the input shaft seal. Because that is where the leak probably is.
The oil will accumulate on those valves from a seal leaking above it.
While you have the trans out, check the damper on the flywheel.
If any of the springs in it are loose, replace it.
A worn out damper can send shock loads to other parts of the trans, causing them to break.

I love that! The trans oil level is in the safe zone on the dipstick when checked when warm and running. Checked it today after a drive. I may just sit tight for now.
