Did you even bother to read what those 2 trouble codes mean?? As a Master Tech and advanced transmission builder, IMHO (I don't mean to sound rude or like a jerk), you have no idea what you're talking about. Stick a fork it that transmission, it's done!

Thanks for all your input, I will continue to try to understand this issue and why it doesn't make sense.

So I took the scanner with me to work yesterday so I could monitor what's going on with the transmission while it is having it's issues. After work I plugged it in to monitor the speed sensors, temp, calculated gear ratio. Drove it for around a half hour and the thing never acted up once. Just shifted and performed beautifully. I did notice that the temp was up to 215 degrees so I'm curious if higher temp is related, either a symptom or a cause. Have also had suggested to me that as the transmission works through its adaptations to temp and clutch fill time that it may correct this issue on its own. Going to see if I can run it a little longer and harder today to see if I can get it to act up or make the temp climb higher.
