1940 Transmission leak

I use a boring head in the mill. (the tool advances with every rev of the head)
Toolbit is ground per the O-ring bible.

I was afraid you would say that you have a mill. I only have an antique lathe. Besides the difficulty in assembly, does it matter if you groove the shaft for the o-ring? I'm thinking of grooving the rear of the shafts, reverse and cluster gear, and putting the cover over the front of the cluster shaft like I pictured. That way I only have to carefully insert the shafts from the rear.

I used to O-ring the shafts on Model A's, but had lots of knifed O-rings, so went with this setup on the V-8 transmissions.

I am guessing that you want to fix this with out removal. Drain the trans Clean the area at the rear where shafts are with brake clean,, compressed air install drain plug, remove fill use shop vac with longer hose hold over fill hole apply some brake clean to shafts the vac will suck it in cleaning this area let it dry then still with the vac on trans fill put wicking loce tite around the shafts it should suck in , leave this sit for 2-3 hrs then apply black silicon rubber on the out side let that set up for at least 24 hrs. fill trans and hopefullly it woun't leak. Did this with my 48 trans front shaft worked well Good Luck Laurie
 
Your "wicking loc tite" idea reminded me of something. There's some windshield sealer out there, think it might be a Permatex product, that is thin viscosity that might be a fix, too.
