Re: (ET) Well the transmission is happy to see me.

Bottom plug. Was raining a lot this weekend so I can't see if any more leaked, but I went out and bought some 90/140 weight dino juice and I'll swap it out tomorrow just to be sure.
Meantime I got the steering fixed: The shims I bought from Amazon are great, every size under the sun. I selected three shims that were thick yet just enough to get the new cotter pin in there (loaded with anti-seize). Turning is back to normal, however I can see that the sector gear is a bit more worn on one side than the other. Will re-adjust so the least worn teeth are engaged when the wheel is centered, that way it will wear the best teeth in normal driving.
Tomorrow, there will be oil swapping again tomorrow. Then that should be it for another 20 years. Hopefully.

If the leak is from the axle seals, it's probably too late and you're looking at replacing all the seals - which would mean you could continue using synthetic.  If the leak is at the plug, maybe there's no problem (until there is, in which case it's too late and you're looking at new seals).
So if the seals aren't leaking yet a flush is a good idea.  If it was me I wouldn't assume ATF has no synthetic additives or other odd stuff. I'd use a light weight non-synthetic motor oil and jack up the rear wheels while you spin it up to splash the oil around.  (Motor oil doesn't have the high pressure additives a loaded transmission needs.)
Motor oil is built from the same stuff as hypoid lube, so you know they'll mix well and give a good flush.  ATF has a lot going on in there, and it's anyone's guess how it'll mix with gear lube.

    That's a problem then. I may just have to order oil from the internet
    and do another swap-out. What's good to flush a transmission again, 
atf?
