The cheap, temporary fix cost me less than 10 bucks. I kept the old 3 speed that I pulled out for the swap. Bought a new output shaft seal, swapped the slip yoke on the driveshaft that I had also kept, and slid it back in yesterday.
I probably won't dig into the overdrive for a couple months at this point. I'm not in a rush to fix it at the moment.
The slots need a good polish, but I think they'll clean up well.

Didn't have much of an issue swapping the old 3 speed back in. The "guide pins" I made to install the overdrive a couple years ago proved their worth again yesterday.

The old 3 speed sounds like it's got straight cut gears in 1st and 2nd, but not in third. I added fluid until it came out the fill plug hole yesterday before going for a test drive. I still need to check if it needs more after running through all the bearings and such. It has been sitting dry since I pulled it.

What I don't remember is if the gear noise was present the entire time I was driving the truck with the old 3 speed. I've done a few things here and there since swapping it out that has reduced the overall noise in the cab, so it's quite possible that the overall cab noise while driving was drowning out the gear whine. Now the cab is much quieter, so the transmission whine is more noticeable.

Whichever way it is though, I'm going to run that transmission until it either blows up or I park the truck for the extensive rust repair. Fun stuff!
