transmission going bad?

Unusual vehicle noises can only be diagnosed *hands-on* - too many possibilities.

What gives you the impression it "almost doesn't want to shift"? Noises, as Pushrod said, need hands on inspection and diagnostic testing; these transmissions are not prone to concern, but many different inputs go into determining when shifting should occur. So, along with hands on testing for the noise; diagnostic testing using a diagnostic tool that can interface with the various control modules would be quite helpful for the shift concern.
