1998 Ford Explorer diagnosis/HELP?

I believe the front seal went out, after driving and all the fluid came out at once, I had nothing. Thought it was the tranny pan gasket, however replaced it and filter. While adding fluid on my second gallon, fluid everywhere. Was wondering what else it could be? And what else should be replaced, while tranny is out. Or if its even worth it, with so many miles and all the same problems as other 1998 ford explorer owners, like the timing chain noises, rough idle, drivers door not locking and I never went into ford to have the recalls done.
