You mean the auto is easier. So there may be 1 single type of terrain where lower isn't better. The manual transmission pretty much negates that as well.Mainly in dunes, with a 4:1 4 low may be too low and 4 high may make it a little difficult to get moving especially with a manual. They wouldn’t make 3 speed transfer cases if you always needed the lowest 4 low, having a range from to 2.7:1 thru 10.8:1 gives you the ability to have the perfect ratio for anything. All depends on where you’re going with the rig and whether you have an auto or a manual and let’s face it in 99% of situations the auto is better.
