If just recently changed my clutch on my sunfire and I'm seem to have a problem with my speedometer, when I start the car change gear my speedometer does not move I hit a speed bump and all of a sudden it starts acting up it will go up and down wildely with out showing the right speed, I keep driving press a couple of times my clutch pedal hit another speed bump and it comes back to normal, and it will work fine till I turn off the engine.

do they need to disconnect the speedometer to change the clucth?

is the speedometer connected to the clutch?

The vehicle speed sensor is what sends the signal for the speed. They would have had to unplug it to remove the transmission in order to replace the clutch. I woud start by checking the wires at the speed sensor. Make sure that there is not a broken wire. Give them alittle tugg aswell sometimes the wire breaks inside the wire insulation and is hard to see.
