Did some digging... no used transmissions in my area currently... salvage yards are wanting close to 1k... no trucks being sold for parts on CL...
I believe for the time being, I'm going to attempt to seal it up. Going to drain the trans, clean/wire brush the area and fill the webbing with epoxy (either jb weld or something similar). Hoping this can get me by for a bit until I can either track down a transmission or have time to pull this one apart and replace the tail housing as of coarse, it has to be fully disassembled to do so.
I may call the local driveline/trans shop and see if they may have one laying around they would let go cheap (highly doubtful).
If this don't work... not sure where I'll be as I don't have that kind of money right now and most likely wont have (to spend on something like this anyways) for a good while. If it will seal it up enough to be drivable, I'll baby it around until I can just get a reman unit.
