Re: Help identifying a 3spd transmission

Ive gotten progress!
Sorry for the delays...life keeps taking over. Between dealing with the city about permits for a garage we're building, emergency rebuilding furnaces, cutting podcasts...its been busy. As a result, time spent on the car has dropped to a few minutes here or an hour there.
Having said all of that, we got the transmission tailshaft contraption apart. The layer-cake of fabricated parts, weird use of sealants and gasket papers...it was complicated to say the least. We undid the coupler that held the ball-end of the torque tube to the tailshaft housing only to find that there wasn't clearance to undo the saddle bolts that held the u-joint on. Once that was delt with, we couldn't get the u-joint/yoke off the shaft due to the angles involved (picture undoing a bolt at the bottom of a bowl, but you can't use a ratchet due to clearance issues).
Eventually we got through that and got the first layer of the contraption off to find a perfectly flat piece of steel with no fasteners...that wouldn't come off. We found two screw threads inside the transmission, which was the clue we needed. Dear ol' dad had placed a sheet of gasket paper over the entire plate, fasteners and all...so we had to go dig for them. Once we found the fasteners (big countersunk slot screws), they had to be dug out and extricated. Turned out there were actually 4 of them...but two were cut to the exact length of the holes they screwed into so they were flush with the inside of the trans. Very fun treasure hunt to say the least.
Long story short, we got to the bearing and removed it. Sure enough, she is a wide-open roller bearing and clearly where all the oil is leaving the transmission from. I've purchased a new bearing that is double sealed, which should fix most of the issue and we will RTV-up the rest to try and slow it as much as we can. I've gotten a breather muffler to attach to the transmission so the pressure has a direction to vent. Hopefully this bearing is the solution to the issue and I can actually drive the darn thing!
