Well, this is a new one for me. I looked at this car today, was told it had a leak and about where the leak was. Something had struck the condenser and put a hole in it. Funny thing is that it had 4 (four!) lines going to it. So I'm scratching my head while I look up the replacement part. Turns out about the top 1/4 of the condenser is a trans oil cooler. Glad to see a stock cooler, but it had me confused for a minute.

Anyway, no real questions this time, just thought so e of you might find this interesting as well.

I bought a can of 134a at w**-mart that had a stop leak, oil, and dye in it. It also had a hose and a gauge, so now I'm an AC pro!

Thanks for the tip. Since modern transmissions use internal thermal valves to regulate trans oil temperature and flow thru the cooler; it makes sense that they no longer need to use water temperature as the trans oil thermal regulator, and can use air over cooling for the trans fluid. We are going to definitely see more and more integrated heat exchangers and one part number cooling stacks (radiator, oils cooler, PS cooler, A/C condenser, etc.).

Much of the Mopar line is built that way.

Charger / 300 / Magnum vehicles from 2005 forward have the trans cooler in the top 4 inches of the condensor.
