Draining Transmission Fluid?

[Somajunkie]

Hello I know this isn't in direct correlation with OP problem, but I have a prolem w/ my Transmission fluid leaking. I am a noob and just recently purchased the Supra. According to the guy who sold it to me his mechanic overfilled the Tranny with 2.5qts when in fact it should be 1.7. He told me to replace the fluid, drain the old and replace w/new. Every time I use it it creates two little puddles, the more i use the car the bigger the puddles. The leak seems to be coming from somewhere by the tranny pan but I'm not too sure. The puddles are not extremely dense and at most are the span of my extended hand, but they still worry me. So if you guys could be of some help i would greatly appreciate it!
