Shift, skipping D

Car was running fine, all of a sudden will not go into 3rd (drive). Still have 1, 2, N, R. P with no issues. Didn’t hear anything pop, or anything happen, and still shifts smooth into what I have. I have 727 torqueflite and thinking cable….but not sure. Any ideas? Newbie mopar owner. Thanks for help! Any videos out there on how to fix, sick of being in the shop and would like to try working in my own…just want to start looking at the right spot.thanks!
