    Speedo on my 2004 Silverado registered 45mph sitting in drive way. When I started truck-it dropped 10mph. I did this til it read zero and then it seemed okay.

    Next morning it wouldn't work at all.

    I have a 2005 Silverado with 93,000 miles. The speedometer will read whatever it wants to standing still, then will increase by actual speed. Sometimes it stays off by the same amount the whole trip, sometimes it goes up or down. Occasionally, it works correctly. My father-in-law has a 2006 Silverado with 40,000 on it and sometimes the speedo just goes to zero.

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...

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.

2003 GMC sierra 1500 ( dealer rip off )

if you went to a dealer then that sounds about right. they tend to be expensive. you got to remember though that most the time 90k mile maintenence includes radiator flush, oil change, tranny oil change, emissions checks, possibly water pump check. cooling system pressure check. abs checks, brake checks, steering and suspension checks. there is alot of maintenance that can be done. you need a list of the stuff they are trying to charge you. honestly if they do all the work required then 3300 my not be to bad

This is a common problem you just have to have them replaced. The dealer should replace them for free if your truck is under waranty.

Speedometer quit working

you might need a new speedo cable but if its a sensor you could need a new sensor and that might not be cheap.
