It's a bolt not a nut, the size is M14x1.5 near the bottom of the differential. Not a bad idea to replace it with a magnetic one, the magnet inside the transmission is probably already covered in shavings and won't catch many more.

Transmission holds 2.3 quarts of fluid. Mopar ATF +4 works, 10w-30 high mileage oil works, and synchromesh works.
 
to refill it, you can remove the back up light switch and fill it thru the hole.

its 2.1 quarts.
i always hated buying a 3rd quart just for the point 1.
and then there is trying to eyeball 1/10 of a quart, not the easiest thing to do. And i probably didn't even need to add more than 2 because im sure there was 0.1 qts that stayed in the tranny.
