It depends on your situation. If you don't need 4lo don't use 4lo. I have a rubicon and it is geared so low, you can't travel at a decent speed. I had mine in 4lo at Fort Fisher last fall (read it on here) and I could smell the tranny. I switched to 4hi and no more problems. I don't think there is one answer for all situations.

So I read something in a post today that I would like to know the answer to. I read that if you run in 4 wheel high at around 15mph for extended periods of time your tranny will overheat. I know this for a fact, because it has happened to me on the beach twice. 
I have since added an aux transmission cooler. I thought that may fix the problem, but the post I was reading today stated the cause for this was due to the torque converter not kicking in until you reached 3rd gear in 4 wheel high. 
The recommendation was to run in 4 wheel lo to avoid this. Is this accurate? Should i be in 4 wheel low when riding at the beach. I always assumed i would only use 4 wheel low if i got in a tough situation. Is it OK to run 15 mph in 4 wheel Low for extended periods of time.
Anybody have any knowledge on this subject.
