Thank you for all the great advice and encouragement! I'll definitely reach out to Rob and or Nick when the time comes.
I'll double check that the linkage is right before I tackle the removal. The only thing that would have been disturbed is the fit between the extension (#108295), the crossgate clevis (#105783), and the the control shaft assembly (#103130). There were two bolts fastening these 3 parts together (see pic) and there was a little bit of play in the non threaded holes on 2 of these parts that would cause a slightly different orientation on reassembly.

Would that cause my symptoms?
Yeah, the nut (103076) backed off completely and ruined the threads on the nut. I got a new nut and gasket from DMCH and got the cover aluminum welded locally by a guy that had 41 years experience (I found out when I picked the part up he owns an early vin unrestored DeLorean).
New nut locktited, torqued and peened:

Apparently a tell tale sign that this nut is backing off is when you hear gear whine when you are in a gear and let off the gas and coast. I was hearing that in 3 and 4 but thought it was characteristic of the box and didn't ask.
Oh by the way the most difficult thing about this repair for me was getting the 5th gear detent screw out. I had to enlist help, and it turns out that there was a ridiculous amount of thread adhesive in there.

Im not sure what happened here all my photos are visible in during writing and editing of this post. I've contacted the Administrator.
These were taken with it going in. I Have headers, no crossover pipe to contend with.
I don't have a picture, but I raised the engine and inserted a short 2x2 and a small stack of door/window framing shims between the back of the oil pan and frame cradle. This keeps the engine level or even a bit tail high when the weight was let down on it. I needed to use the block method so I didn't have any obstruction from another jack where I need access to pump the trans jack handle. I'm sure I could have used a small bottle jack offset to one side of the oil pan, but I didn't have to use.
Loaded and ready to lift. I used a Motorcycle/Atv jack. (Harbor freight) It cradled the transmission perfectly with a little blocking to level tranny.. I loaded the transmission onto the jack in location. The Jack stands were at full extension but was not quite high enough to roll the everything under at once.

These photos loaded out of sequence but you get the idea.
Centerforce clutch with finger weights. If you do the rear main seal but don't replace the clutch, you need to get a clutch disc alignment tool. I made one years ago of of aluminum round stock (un-splined)
Attachment 47601
A refurbished clutch fork. Note: Its a good idea to remove the fork and lube the pivot ball and socket with a mixture of 50/50 moly grease and anti seize compound. (Rob Grady tip) Rob also has the rubber cup/cover seal if you need a fresh replacement. I'm guessing all the DMC vendors have it though.

I bought some longer M10 x 1.50 bolts and cut the heads of to use as alignment dowels in the lower bolt locations.

Thanks for the detailed information Dennis! Hopefully an admin can fix the pictures.
Today I double checked/adjusted the linkage described above and test drove it. No joy. It's still doing the same thing. So I jacked the car up on 4 floor jacks and prepared for surgery. Tomorrow I'll get as far as possible with removing things, draining the gear oil, etc.
Question to all: is it possible to remove the clutch slave cylinder off the transmission without disassembling the line? ( ...is there enough slack in the SS flexible line to move the slave and hard line out of the way?) I'd really like to avoid having to bleed that system again.
Thanks.

Yeah, you can unbolt the line clip on the case bolt then unbolt the slave cylinder and lift it out of the notch in the bell housing. Use some zip ties to hold the metal line and slave up out of the way.

I bought some longer M10 x 1.50 bolts and cut the heads of to use as alignment dowels in the lower bolt locations. This works nicely for getting things lined up and square to slide forward into place. Once the upper bolts were in place, the lower locator bolts came out with finger pressure.

Actually not true. DMCH and therefore probably all their vendors don't carry this item. I sourced them through my European Renault sources years ago and supply a new one with every clutch we sell. This ovwerlooked item is critical to avoid the dreaded 'clutch ball squeak' that is so common with these cars.
