P0715 DTC and correction

If the electrical connection at the transmission is leaking oil I would try fixing the leak before dropping transmission pan as cleaning and stopping the oil leak may correct the P0715 code. You will need to clear the codes with your scan tool. I don't think they clear by themselves.
IF you decide to buy the conductor plate to effect repairs I would purchase the complete plate with the valve, sensors and solenoids, not just the plastic plate. It's your call, but why take a chance on the problem being just in a bad connection. The sensor itself may be bad.
I got the manual pages for both error codes but the thing is that the codes were pending probably from the TCM sending them but I don't think I can access and clear the error from the TCM directly. I may have to unplug the battery for a bit to see if that clears it. Thanks for the video example and suggesting I get a conductor plate kit if that is the problem. I shall search once more for the source of thine issue.
