I had a similar problem and ended up replacing both the lines and the radiator.
You will have to replace the radiator, the cooler is not repairable.
The tanks on the radiator are plastic and the lines vibrate causing the tanks to leak were they screew into the radiator. REPLACE RADIATOR.
You will notice two lines going to your radiator from the transmission. One is a service line and one is a return line. The radiator has a transmission cooler built into it. If you have trans fluid in the radiator chances are the trans cooler is leaking. A little trans fluid in the radiator will not affect engine cooling BUT as soon as the pressure drops in that transmission you may very well have radiator coolant sucked into the tranmission and that will ruin a transmission in a hurry. You need to get this checked out as soon as possible.
upper line on radiator connects to transmission front
The line probably goes from the transmission to the radiator. The engine isn't involved in the process of cooling the transmission fluid. Replacement would be as simple as removing the old one and installing a new one.
Depending wether the line going in has an o-ring or if it is just threaded you will either need to replace the o-ring or use a pipe thread compound to seal the fitting.
I wouldn't. Replace or repair the line instead.
how much to replace the transmission line in 2006 Chevy impala
Most Lube shops will just drain your trans fluid in the pan and replace the filter. If you are doing it yourself, and you own an automatic, just locate one of your transmission line that is going to your radiator. They are usually located underneath or bottom of your radiator. Normally, they are connected with a rubber hose (because of vibration, just remove

The radiator has a transmission cooling tank in it. Evidently the tank has cracked. You may have a crack in your radiator your transmission cooling line runnz in your radiator good luck
