There are three fixes possible for the gas gauge....but I would have this troubleshot by a garage:
1. The gas gauge itself does not work anymore. It could have just finally "died". Problem is, you cannot replace just the gauge. It has to be the whole instrument cluster. Having a garage shoot power TO the gauge and then shot the gauge itself will let you know if the gauge assembly is bad.
2. The fuel sending unit is bad. This means the wiring to the gas tank fuel pump/sending unit is bad and does not work. The signal is not being sent to the fuel/gas gauge. This means the fuel pump assembly needs replacing.
3. There is a wire problem somewhere between the gas tank and the dash to the fuel gauge.
The transmission leaking but still reading full just means that there is plenty of transmission fluid in the transmission. The drips or spots you are finding are not enough to "read" low enough. Unless you have a HUGE spot of tranny fluid left on the ground, I would just think about a transmission fluid filter change. This way, a new pan gasket will be installed and fresh fluid filled to the proper level will be accomplished on your car.
