Give a newb a break.... first I'm building a 2015 JKU Sport Automatic. I'm looking to upgrade the t-case to atlas 4-speed. I've read everything I can find regarding how it will not work due to software. But I have also seen AEV promoting a programmer that will let you reprogram for a lower low gear in the t-case. My question is .... can I simply use the programmer every time I switch to a lower gear? For example.. . If my tcase were programmed for 1:1, 2.72:1, 4.3:1 and 10:1 and I have the Jeep programmed for 4.3:1. When I reach a point in the trail where I need say 10:1 could I at that point reprogram for 10:1 as the low gear without going into limp mode? Forgive me if I am overlooking the obvious.
