I have a 22 silverado with the 10 speed. While sitting in park or neutral it acts as if it is trying to engage. I can monitor data and number 2 solenoid is energized sometimes for a few seconds up to several minutes. Once it de-energizes it stops trying to engage. I can not find theory of operation as when clutch solenoids energize. I replaced TCM but still does it. I know they have had problems with the valve body but would that cause the shift solenoid to show power?
