When all the solenoids set electrical codes 999 times out of a thousand the problem is in the wiring harness, not the solenoids. Changing the solenoids is almost certainly not going to fix this.
If this vehicle has the 5R55S transmission in it you should look at the case connector, water from the AC drain drips down on the connection and causes them to corrode. I have had to replace the solenoid block and pigtail wire harness on several of these.
If it has the 6R60 transmission in it there is a possibility the lead frame connector inside on the valve body may have a problem, I usually see speed sensor codes for this one but I have read of solenoid issues here too.
Make sure the connector on either one is tight and secure.
Truck went back in after issues could not be replicated. Truck started acting up for the technician to see in person. He told my wife there could be a valve issue since the truck had trouble shifting into reverse and sometimes drive.
We were told it could be a $4000.00 repair. The truck is worth 6000.00 at best, my wife wants to repair the transmission for now.
