Ok , read your post wrong. Could be your 3/4 shift selenoid. Yuo would have to drop your tran oil pan and theres 2 solenoids, one is 1/2 and the other is the 3/4/ they are both the same part I believe just not sure which one is the 3/4. Online search will probably help

If they work from the scan tool, they should work from the PCM. Might be an intermittent or poor connection though. Check the electrical connector on the passenger side of the transmission. Make sure all of the terminals are tight in the harness connector, and that the harness connector is fully engaged with the transmission connector.
