I notice on my way home from work today that my speedo has stopped working, it does not tell me the speed and the miles do not count up - anyone offer any solutions for me to check.

 

Either unplugged or more likely just a worn out speed sensor. My recollection is that it's basically a plastic gear & the teeth wear out. Get a new one. I think mine was $80 (?). It plugs into the right side of the tranny case.
