First of all, DO NOT drive your Jeep, or even start it with a dry tranny.
Trans fluid lines: 4 quick discos, any of them can pop off, or just fail. This would pump all the fluid out of your transmission. They use a special seal consisting of o-ring, spacer, o-ring on the male end with a plastic clip that seal the line when put into the female end. If you're missing an o-ring or a spacer it will spew fluid under residual pressure.
Front/Torque Converter Seal: If the seal at the front of the tranny goes it can sometimes leak a little or leak ALOT. I found this out when I put in my tranny after replacing the torque converter. The boys at NAPA gave me the wrong seal. It was the right diameter, but about 1/8 inch too narrow. After I put it all back together...I laid down a James Bond smoke screen about 20 miles out on the road. Had it towed home. Got the right seal, dropped the tranny again and replaced the seal with the right seal, not a drip since. If there is tranny fluid dripping out the front of the bell housing after everything is cleaned up this is most liklely. Upside is the seal is only about $10...downside, the transmission has to come out, the torque converter has to come out just to replace the seal.
Too much fluid: Only two reasons that there would be too much fluid in the tranny. Either too much was put in (duh) OR there could be a leak in the heat exchanger in the radiator thus adding coolant to the tranny fluid as it passes by. If this is the case there's tranny fluid in the coolant AND coolant in the fluid.
These are all I could think of. My suggestion would be to add enough fluid to let it leak, and see where the leak is coming from...then make repairs as needed. Good luck.
