Shift Cable slack orworn bushings?

2019 Tundra w/ 47K; shift selector does not seem to engage Park correctly. While this is not a problem yet, don't want to wait till it becomes a problem. the shifter position matches the gauge. When I move shifter to Park and let off brake, I hear a click like shift cable is out of adjustment. From little that I know about this, I assume there are bushings and linkage up top that could wear and down below at the transmission. Any advice will be appreciated before this becomes a real problem. As of note, the truck has mostly city driving which means lots of park to drive movement and back to Park. Where are the most likely areas for wear to occur.? It seems far fetched to think the shift cable could be worn out already.
