Hello, my name is***** usually means the transmission relay is failing so replace relay for this code. The other two codes means the computer detected high temp operation of transmission and put it in safe mode. These two codes usually mean the transmission range switch has failed which has temperature switch built into it or the PCM itself has failed. I'd start by replacing relay and transmission range switch, if problem still exists replace the PCM. Let me know if you have more questions or if there is anything else I can do to help. Thanks.
I've seen this many times and the most common cause is the PCM but since the transmission range switch can also cause this and is a cheaper part that is where I'd start. Since problem is intermittent it is going to be hard to test. I have not seen any ground problems cause this, a ground problem should also cause other issues besides this and more codes. Let me know if you have questions, thanks.
