2017 SS 5060 miles (purchased 12/2024 with 2800ish).

Yearly oil and filter change. Should I also do a a rear diff fluid change and transmission fluid change? I would assume the fluids are breaking down due to age? Near as I can tell these fluids were never changed (carfax service records).

Any help would be appreciated.

In my opinion, you can't go wrong in doing them if unsure or can't find previous service records. Fluids and filter changes/swaps are much cheaper than component changes.
If it were me, I'd do it all, just to be sure. Then you know going forward what's been done since YOU did it.
