Issue while engine is cold

So, my wife told me recently that her car was acting "funny" She claims that it will occasionally not rev over 2k RPM, then will eventually shift. Other times it will rev to around 5k before shifting to the next gear, and giving a jerky shift in the process.

I'm trying to diagnose this issue and am having no luck as I've not been able to replicate it myself. She claims she's not trying to take off fast when it revs high before shifting, but I drove it and nothing. SHe also claims that it usually only does it after it sits for a while. If she goes to work and gets off work it will do it, but if she runs to the grocery store and doesn't give the engine time to cool it won't do it.

I have no idea, I'm just hoping it's not the transmission. I was thinking possibly TPS, but it seems this car doesn't have a normal TPS, but 2 pieces one at the throttle and 1 at the pedal?

I forgot to mention it's a 2005 v6.
