Re: 2000 K3500 trans or electrical issue

Make sure the electrical plug to trans is securely connected....remove the plug and check inside the plug...ANY oil contamination means the socket and wiring loom in the trans needs replacement .

Also check the ground wires to the chassis and trans....

I would also look at the trans oil...if its burned up or black, drop the pan and check the contaminants present....
