so i crank the jeep this morning cause it’s supposed to be icy roads this evening and overnight. put jeep in reverse and back up. when i went to put it in drive the shifter moves back and forth but remains in reverse. even when in park. does the shifter have a cable or linkage? hoping it’s an easy fix as i have no real experience with automatic transmissions. any thoughts or suggestions to look into on my next days off? thanks in advance.
