long story short...my radiator and or AC condenser and or transmission cooler has what is believed to be transmission fluid all over it. I am suspecting a leaking transmission cooler or cooler line. Tranny stopped pulling so I checked the fluid and it was dry on the stick. A few questions...if it is the cooler itself leaking, can I take the hoses off, and install a new aftermarket cooler? and if so, where can I mount the new one? I'm thinking this might be a cheaper yet just as effective repair. The current AC condenser / transmission cooler "both in one" setup that came from the factory can't be cheap. Advice and or comments appreciated.

Try to get a better look at the leak source. The top hood latch plate unbolts and lifts up for a visual inspection. Usually the hose end clamps loosen up and start leaking. The lines are held into the cooler by retainer clips.
I've never had to replace a condenser/cooler assembly unless it got hit.
forgot to mention...only the passenger side of the radiator / condenser has fluid on it...the drivers side where the transmission lines connect doesn't have any fluid on it so I guess that rules out a leaking line. does the trans. cooler run the whole length of the radiator? maybe the leak is on the passenger side. it's such a mess down in there and tight clearances I may just have to pull the front clip just to see what's what.

Partner what was ur fix to ur problem mine has the same issue and I'm about to change the whole condenser since its leaking trans fluid. The leak is somewhere from the front passenger side. Thanks I appreciate it.
The ATF cooler occupies the first few top rows of the condenser. I believe that the ATF lines attach at the drivers side and the A/C lines attach at the passenger side.
If it is difficult to see where the leak is because of everything being wet or grimy, degrease the area.
