Ok I have a little bit more helpful information… now that I have the CTS3 monitor I can see exactly what gear I’m in.
in second gear it doesn’t shift until about 24-2500rpms. It then shifts into 3rd, rpms drop to about 1900, and a second later it feels like it’s shifting again, but it’s still in 3rd and RPMs drop a bit further. I shift into 4th just fine.
I will admit I’m very transmission naive. I can make my way around the engine compartment fairly well, but when it comes to transmissions I’m dumb. This could be completely normal, I don’t know. Any ideas? It’s $180 to diagnose at my local transmission shop, or about $250 just to drop the plan myself and swap in a John Woods valve body that should correct the temperature sensor and perhaps this shifting issue. I am confident I can get that done. I’d hate to spend $180 extra just to find out I need to do the $250 fix. Or does this sound like a torque converter problem, and could the two be correlated?

If you have a code and Mark said it needs to be diagnosed, that's what you should look into. Have you tried clearing codes and see if it comes back?
Also, I wouldn't run 2 coolers, not sure if there is a negative effect.
If you want a VB, then get one and see if anything changes. as Mark said it's rare for the sensor to fail

The "shift" you feel in third gear is the torque converter locking. It is working as designed. Nothing to fix there.
