Automatic Hot Oil Problem

I recently bought a 2010 Sport (automatic) after a few years of owning a TJ. I've enjoyed the Jeep so far and just recently started to make a few minor cosmetic mods. I was searching the forums for a few things, and saw a number of alarming posts about automatic transmissions overheating pretty easily while off-roading. I don't do any serious off-roading at this moment since the Jeep is my DD, but I'm a little concerned that people had their trans. overheat with light off-roading (logging trails), which I primarily do. Is this a big problem or just isolated to a handful of Jeeps? I don't want to dump a lot of money into the Jeep and then have to worry about the tranny burning up every time I go off-road. I know I can get a trans. cooler, but I've heard it voids the warranty. I also read some of the tips about using 4-Lo, turning off OD, etc.

It's 4hi uphill or on sand that overheats the transmission the quickest.

There are several things you can do.
Install an additional transmission cooler.
Use 4lo, O/D off, transmission in "D", as much as possible.
Install a transmission temp gauge so you can keep an eye on the temp and take action before it overheats.

Your best bet is the cooler.
