Thanks Matt,
I was going to Autozone to have the code reset and when I accelerated into traffic got a loud transmisson clunk as before and the engine shut off.
Before that the VDC light had gone off and only the check engine light was on.It started right back up ok but had zippo power in drive and not much more in Low.VDC light is now back on.Drove back home
I pulled the ECM out and it had exterior rust but the housing to the circuit board was not compromised.
If I ever get this thing "right" I am going to sell it asap.One of the most disappointing vehicles I have ever owned
