My neighbor's Rubicon is acting up. When you put it drive it's like it locks itself in low unless you play with the shifter lever. Here's what he describes ... "When in “D” and while moving the gear indicator will go blank but transmission is actually stuck in “L” (but doesn’t display that). Likewise, when in ESP, the gear indicator goes blank and you’re stuck in the last gear you were running in (inability to manually shift up or down)."

Any ideas?
