Anyone ever have this?
Has Happened several times when backing out of the garage.

Never heard of it. Thought powertrain trouble codes were 4 digits...

That would be the VSS (vehicle speed sensor) on top of the rear diff. Remove and clean or just replace. Also inspect wiring and connection. Fairly common. I'd suspect yours is gunked up. Might be time to change your rear diff fluid.

Actually all the fluids were just cahnged last summer/early fall
That was one thing I was afraid, that maybe there was not enough but upon inspection everything seemed fine.

I drove the truck all weekend, first day out of the garage it duplicated everything.
That night after being parked at work for 12+ hours it did everything all over again before getting out of the parking lot!

However, the next 3 days of driving it never happened again?????
So now I am letting it sit until Thursday. Have some things to do at home and will drive it again then and see what happens.
