What is your question?
Selonoid replaced at 20K and acting up at 50k. Had many service flushes with the same fluid replaced. Shifts normal in cool weather, but hard shifts stop and go when motor temp raises to 3/8 on temp gauge. Can anything besides selonoid replacement help?

Do you have any pending codes in the ECU? What solenoid was replaced? Which shift is still too firm? Might be time for a remanufactured transmission.
As i am a old tech/mech i bet that if you put a HUGE trans cooler on it this may help. I just got a 2000 century and when a go for a highway drive and go local it has hard shifts. "Shifts normal in cool weather" ? Keep that trans COLD! Right?
