The VSS, vehicle speed sensor runs the speedometer and from that, the transmission knows when to shift. If the computer things the car isn't moving, it won't shift from first.

There are actually two sensors on this vehicle. One is on the transmission and the other behind the dash. I wouldn't expect either to take more than an hour labor. The parts are another story. I can't find a listing for them.

I attached a pic for you to see locations.
