I was doing some very light snow wheeling this weekend and I got a 'Hot oil' warning light. I was just driving down a snowy trail and the only things of interest that happened before hand were a bit deeper snow so T/C was working hard for a maybe a couple minutes and it was rather bumpy and things got knocked around a bit. I wasn't doing anything serious and was in 4hi.

You need to install a transmission cooler, period. You shouldn't be wheeling your JK without one. Heat is the number one killer of automatic transmissions, and from the factory they are simply not equipped to handle higher temperatures.
A transmission cooler will improve the longevity of your automatic transmission significantly. This is the one I recommend for your 42LRE transmission:
