I'm leaking Transmission fluid off the radiator, there's a metal fluid line from the rad, then a crimp (where it's leaking) about 6-8 inches of hose, another crimp and continues back down a metal fluid line.
Can anyone grab me a name for these parts or a quick fix for now would be great.

First thing to do is check the transmission fluid level and check for leaks. If the transmission is very low on fluid, for example a cooler line broke, it would cause this situation due to no pressure. If you do not see any outside leaks, but transmission fluid is very low, check your radiator overflow tank, if it is overfull and milky, this would mean the Trans cooler that goes through the radiator is leaking fluid into the coolant system.
It sound like the transmission cooler inside the radiator tank is leaking into the coolant. You could try to fix it yourself, but without the proper tools the tanks are difficult to R&R. I'd try to take the radiator back to whoever you got it from.
Your transmission fluid runs to your cooling system to cool the transmission oil. So, in answer to your question, one of the two transmission lines (one in, bottom and one out, top) could be leaking from the cooling system.
Bring your vehicle in for a cooling system pressure check. Another thing to keep in mind when inspecting leaks is that where you see the leak may not necessarily be where the leak is from. While the leak will drip down, the wind from when you're driving will splatter the leak all over the under-carriage of your vehicle making it look like leaks are happening where they in fact, are not.
sounds like trans cooler in radiator has breached leaking coolant into trans and trans into coolant.i know for sure that nissan extended the warranty on radiator for this problem.i am not sure the mileage and time limits.but if you fall within those limits they should also warrant the trans as this would be the source of failure(collateral damage).good luck and remember the squeaky wheel gets the grease!1-800-nissan1.ecm relay would not be a contributing factor.
Make sure you don not run low on transmission fluid in your transmission. Low transmission fluid will cost you a new transmission. You have the transmission line that connects to the upper passenger side or the radiator and the lower passenger side of the radiator. Determine which line has gone bad and you can buy a rubber transmission line hose at most Auto Parts store like Parts Source. Cut off out the section with a pipe cutter that has corroded through and replace with the transmission hose. Make sure you tell them it's a transmission line hose your looking for and don't use any other hose and double clamp with a compression clamps at ether end. If it's the connection at the radiator that has gone bad, replace that end and do that same as you would to sectioning off the the corroded line and try not to have more then 3 inches of repaired section. What ever you do, do not add any stop leak, this will create problems with the shift solenoids and check valves in your valve body in the transmission causing a transmission replacement soon after adding. Good luck and keep me posted.
It's probably a transmission cooling line that comes from the transmission and connects to the radiator, which cools the fluid, and returns it thru another line in the radiator. It could be loose, but It probably is rusted, based on the fact that it's 13 going on 14 years old, and probably needs to be replaced, as the leak will just get worse, and if the fluid gets too low, u can ruin your transmission. The steel cooling lines are available at any parts store, both the lines should be replaced if one is leaking. Parts for this are cheap, but labor to snake 5 or 6 feet of line ( x 2) from tranny to radiator takes a bit of time. countrycurt0
