Transmission coolers
I bought it from Auto Zone but NAPA also had them. This was about 3 years ago though. www.rockauto.com might have it as well or www.summitracing.com.
Indy<----- You cut the top radiator line coming out of the radiator back to the transmission. This is the cooled line. If your not sure disconnect the line and have someone crank it over a few seconds and make sure the fluid shoots out of the line or radiator to ensure the correct flow and correct line.
On Durango's with the tow package there should be a small transmission cooler between the A/C condenser and the radiator. On these you can cut the out going line from this cooler and install the after market one and run them in series for better cooling. Then the really cold fluid goes back to the transmission creating more power and better longevity. You could also buy 2 coolers and replace the OEM trans cooler and run them in series.

No need to use the rad and the stocker aux cooler AND YET ANOTHER aftermarket cooler. Talk about overkill. The same person running 3 coolers is the guy who never adjusts his bands or waits until the trans acts up to have it looked at. 
Run it like the factory, and you will be perfectly fine. If you want to add a bigger cooler than the stocker aux cooler, that's okay, just hose it up the same... out of trans, into rad, out of rad, into aux, out of aux, into trans.

Besides, the cooler the fluid back to the trans means better heat exchange and more power with less ware.
