Sounds like the VSS sensor in the tail shaft of the transmission to me...

If you could find me a diagram of where that is at that would be fantastic! Is it on the transfer case or the transmission? 5.7 vortec, auto tranny, push button 4x4 and z71. Please help?

Let me see if this works. Its in the end of the transfer case where the driveshaft connects. Number 10 on this diagram.

Edit: trying again. the part in the red circle

wish like heck that I knew how to fix that kind of stuff :bawl:

Anyone know how to fix this?? If you don't get it figured out soon, start another thread, okay? That is worth getting fixed ASAP, especially if that is a DD.

His speed sensor or wiring for it is bad, he even posted the dtc which is telling him exactly that....
