PO601, 1999 Durango 5.9 ltr
 
I have had very bad luck getting a working PCM for this 1999 Durango 5.9 ltr. Bought one from Flashmasters last June with a one year warranty, and it lasted perfect til now, 1/2020. It was not supplying ground control to trans solenoid causing limp mode for trans. They sent me another used replacement and the trans ground issue was working, but the PCM was not controlling the IAC drivers. The next one controlled the IAC drivers but now throws a PO601,>> Internal Control Module Memory Check Sum Error.<<
All wiring is perfect and no corrosion, high desert truck, no rust or salt issues, so I'm sure it is the PCM, which they will not replace again.
I'm a bit unfamiliar with the PO601, and was wondering if anybody knows if this will prove to be unreliable in the long run. Everything is being controlled as far as sensors and engine runs perfect.
Any Help Guys, and thanks for reading this.:fca5278d:

P0601 trouble code means that a serial communication failed inside the computer at least 6 times.
