So, I've never cleared out my automatic transmission myself, I usually have the shop do it. But since I got this old Supra, I don't want them to clear it all out because it's so old...it'll probably explode. So...I just want to drain it myself and put some new fluid in. So now the question: where the hell do I drain it?? I'm a noob sometimes, forgive me, but I don't know where the cap/valve/bolt is that keeps all the fluid in!
