Radiator gone bad from the sounds of it.

Probably not the best idea to drive it until you make sure whatever is repaired and no coolant will make it's way into the transmission as that would likely be the death of it.

sound like trans cooler inside radiator sprung a leak, time for a new radiator.

Ive seen some tranny's get trashed due to this. Get it changed out before it gets bad. Your lucky the radiator leaked on you. Last one I had come into the shop the cooler leaked into the coolant, and visa-versa, and there was no leak on the exterior.

Yeah, your radiator is going to have a catastrophic failure pretty soon. They're about $200, and super easy to replace. The radiator has 6 pipes that go into it, if you look at it- 2 big ones for coolant, 2 for engine oil, and 2 for transmission oil. The sides of the radiator are made of plastic, and after some time, the plastic becomes brittle, and starts to leak. It eventually breaks, and then you've got a dead rig, with a bunch of coolant, oil, and tranny oil blown all over the engine compartment. Sweet.

Replace your radiator- remove all the lines connected to the radiator. There are several screws across the top of the radiator that hold the upper half of the fan shroud to the front of the rig. There are another couple bolts/screws halfway down the shroud holding the upper to the lower. Don't bother removing the lower fan shroud like the manual says. There are a couple bolts that hold rubber clamps to the radiator, undo these, pull of the clamps, and then simply pull the radiator up and out. Install the new one in reverse, you might have to use an adapter on one of the oil lines, but the adapter will come with the new radiator. Check your coolant, oil, and tranny oil levels after you're done leak testing. Good luck!!

Oh. Well crap. Um, take the upper shroud off, and get in there with a finger and a flashlight. Start poking, see where your finger comes up wet. Also make sure your couplings/hose clamps are good and tight, and not stripped.
