Unfortunately there are some tests that needs to be done to determine exactly what the problem is. If is just the "torque converter clutch solenoid valve", the repair could be around $400, but due to the age of your vehicle, there is a good chance that other problems could come up when the transmission is taken apart.

I have a 2006 grand Prix. Getting this code after changing trans filter and fluid (no flush). The fluid was black and the coolant lines were leaking pretty bad. Replaced the lines as well. Shifting seems mostly ok... Driving for 2 hours in city City and highway there were 2 times where shifting from 1st to 2nd or perhaps 2nd to third either was hard or slid. That was it. Runs really well actually. Thinking a flush may fix all the problems, but don't want to cause more damage. Any help greatly appreciated.

Sometimes after changing fluid, debris can get into the solenoids. Have you try clearing the code? how long it takes for the code to comeback?
