2013 JKU - Regearing and Limp Mode

I am in the process of installing a Rock Krawler 3.5" X-Factor lift and going to 37's on my Jeep.

I decided to go with a TMR truss in the rear and re-gear to 5:13's. As of now the rear of the lift has been installed along with the rear axles.

I currently have the 3.73's in the front and removed my front driveshaft.

My issue is to work on the front I need to move the Jeep back about 10ft.

My concern is if I start the jeep it will go right into limp mode. I have a flashcal, but was going to wait to update the gears and tires when I am done.

I called Superchips this morning and they said as long as I turn the ignition to on NOT run, slip the truck into neutral and push it out, the Jeep shouldn't go into limp mode.

I know kind of an odd question, but want to get some additional thoughts on the matter.

I've read a couple threads on here I think where guys were doing basically same as you.
And they drove the jeep, as long as the DS is pulled or don't engage 4wd. The gears in the front axle
Are just free spinning the computer doesn't know.....
