Hitting the track, but which car to take?

Well, I broke the Dart out of the garage for the first time in a couple weeks. I drove it hard, doing burnouts and rolling burnouts, manual shifting and running at high speed. I pulled over after about five miles and no leaks. I came back on the highway and brought it up to 110 for a mile or so, and there was no smoke billowing behind me as usual. I came home on the back roads driving hard and shifting up and down and really pushing her hard. I pulled in the garage and got the flashlight to check the transmission. Drip, drip, drip. It's leaking badly still. Gotta pull the tranny, no ifs ands or buts. Guess I'm taking the SRT8 to the track on Sunday.
