On a pan drop fluid change it takes about 7.4 quarts to refill it. (I usually just put in 7.5 and check it later)
Pan bolts, PLEASE use a torque wrench, I torque my pan bolts to 8 lbs. ft.
To get a good seal, wipe both pan and tranny mating surfaces with some sort of degreaser that doesn't leave behind a film. I like to use lacquer thinner myself.
But sounds like you got everything done and squared away. Sogood job for you!
