That IS for an automatic transmission. Manual transmissions don't have "park", and you can start the engine in any gear. I'm not sure, but I don't think you could get a manual transmission in a Durango in '99. I don't remember ever seeing one.
Older vehicles used a series of metal rods between the shifter on the column and the lever on the side of the transmission. A deteriorated engine mount will let the transmission sit lower. That changes the relationship between the transmission and the shifter linkage and can cause it to be out of adjustment.
Newer vehicles like yours use a cable. Those aren't affected by engine mounts but they are attached to a bracket. If the bolt holding that bracket works loose, the outer casing on the cable will move back and forth a little instead of pushing and pulling on the cable. That is the most common cause of what you're describing.
