So i found a small leak today in this radiator..... Im sorry if this might sound like a dumb question but i have a no clue as to what this radiator is for my best guess is for the trans cooling any help would be greatly appreciated also has anybody replaced one of these? how hard would it be? thanks all

 

If you follow the lines coming from it, where do they go? LOL

Yes though it is the trans cooler. Where is it leaking from though?

 

the top right corner no dings or nothing there been keeping my eye on it but only time i have seen it drip is once in a 2 hour period after driving it today there was a single drip on the ground not leaking to bad now but could become a problem down the road anybody every replaced this?

 

for future reference, the biggest one is the engine radiator, the thin one in front of it is the trans cooler, and the one to the right of the radiator is for the A/C

 

Well eventually you will have to replace it. But i think you already know that dont you. Years ago a shop could weld or braze them but not with the new plastic ones.
