" When I got it, I drained the tranny and chocolate milk came out. " If that's the case Lee , Drain it and the TC, Flush them both out with a good tranny flush product (?) & refill it again , run it through the gears & Flush it again. The " chocalate milk " means you had water in there, of course. You could also take it to a Tire & Lube shop & have them do it , to save a mess & time.
