Transmission. Should say on the tranny but it usually uses Dextron/Mercon III compatible transmission fluid. There is not a drain hole. I have a drill pump (about $20) so suck out the fluid from the fill hole in the top (about 2 quarts as I recall).
V-Drive - Check the manual but normally they all take straight 30 weight motor oil without any additives. The assitives will make if foam too much and you need straight 30 weight. No 5w-30 or 10w-30, etc. You can suck that right out the top too.
Very easy process with a drill pump and an old bucket.
