Having problems with your GMC K1500 ?
I have a 2000 sierra 1500 z71, which I'm told is supposed to have a c3 tranny. Last night I went from neutral to drive on the gas, and something went wrong in the tranny. Park doesn't work, and through all my gears the truck wont move, the tranny just clicks/grinds/whirs, and my speedo says it's going like 40km/h. I've been told it could be the transmission control module, but I have no idea
Your truck does not have a c3 transmission in it. That is an old Ford transmission. Yours should have a 4L60 transmission in it. I would say that your tranny is toast. You could pull the pan off and you will probably find parts and pieces.
