Who has 5.13 with a auto???
Is it normal with new gears being 5.13 when I step on gas from a red light and my rpm jumps to 2 but comes down and skips into gears quick but settles around 45-50 mph? Is that normal?

Sounds pretty normal. How do you like the gears? I feel like I have better power and ease of driving. Gas milage improvement hasn't really been seen yet. How about yours?

Yea I have superchip as well. I programed it with gears and tires and all. I have 87 octane programmed. Now after I get gears done does a tire alignment mess with them at all? Yea just weird when I'm at stop sign or red light I'll ease the gas when turns green and rpm shoots up around 2 when I'm at about 20-25mph then it settles down to little above 1 and goes fine speeding up it's the take off seems little different to me I'm def afraid to slam pedal to grown cause rpm I bet u shoot up like crazy then come down. But seems like changes gears pretty quick on take off as well.

Doesn't sound too off norm, but double check your programing. In the Superchips the auto trans shift points are set by tire size so take a tape measure and determine the actual high of your tire.
My 35x12.5R17 KM2s aired to 28 PSI for daily driving and ~5000Kmi I've put on them measure in at a just over 34" actual height.

I ran down to four wheel parts and bought the superchip flashpaq after I installed the performance tune I programed in the 35" tires and the 5.13 gears. Downshift is no longer insane and the jeep is much more pleasant to drive.

I did the AEV Procal, about $139., not a performance enhancer, but reprograms for gear and tire size. Made a big difference in making my rig feel "normal".
