How can I check that myself? Do I need a scan tool hooked into the pcm to get those readings?

If you have the 4.3" LCD screen in the instrument cluster you should be able to see oil temperature(EOT) on the same screen as transmission temperature. Coolant temperature(ECT) is a generic OBD parameter that any OBD gauge can see. Think you mentioned something labelled "Coolant" on your mini maxx, that would be ECT.

Ahh sorry, didn't get the technical references but yes I've checked those. The oil and coolant are within a couple degrees and the trans reading is a few higher than those. Not sure if it's always been that way, I never paid attention before but they're all within a few degrees.
