From a newbie, here's a question that the JK owners manual doesn't really answer. When I'm in 4WD drive, and tap the shifter to the left, the transmission shifts into 1st gear. It ALWAYS goes into 1st. Tap to the right and it shifts into 2nd. Fine, I shift back and forth between 1st and 2nd constantly when I'm off-roading. But what if I'm driving at 70 km/h in drive. If I tap the shifter to the left will it shift into 1st gear? This is an experiment that I'm afraid to try.
