Leaky Tranny
I've got a 1987 Ranger 2.9L with a 5spd. manual that leaks. It will pretty much drain it's self in the time between (engine) oil changes. I had a look at it and can't really see where that much oil could be leaking from. The rubber seal at the back where it connects to the drive shaft leaks some, but I don't think it leaks that much...
Is it possible that that much fluid is coming out there, and how hard & expensive it that to replace?

i have a 93 4.0 4x4 5-speed that leaks also, it appears to be coming from the top-rear of the transmission where the case meets the transfer case adaptor. my fluid level was real low also. theres two large hex-head plugs on drivers side of trannie, one is maked "drain" other is marked "fill" drain whats left out, replace drain pulg and add dexron a.t.f. to fill hole until it runs out, replce plug. i checked mine a week after and is still full, will check at next oil change, only had truck 2 months now. had an 88 2wd 2.3 5speed and it never leaked after 200,000 mi. my "new" 93 has only 65,000 mi. i wouldnt think a rear seal would be too hard to replace, ive not done one before.

It's probably the shift rail plugs. Under $15 from your local Ford dealer. I researched it a lot and found there are several ways to replace them. What worked for me was to just remove the tranny crossmember and transfer case skid plate, and lower the tranny supported on a floor jack (I left the driveshafts in place). I had to replace them by feel.
Since I was under the truck I changed out the tranny fluid. Less than a quart of brown goo came out, so I don't think I had much time left. To refill, just run a tube bown from the engine compartment, took about 2.75 quarts, pretty much what the manual said.
It took me a couple of hours, and maybe with a 2x4 it would go quicker without the transfer case in the way. Looking at the tech articles will definitly help.
Good luck
