Transmission has begun shifting excessively. At certain speeds and accelerator positions it will shift up and down repeatedly. Doesn't seem to be slipping and works great on the highway but can be a pain in town. Any ideas?

If the speedo isnt working either, I would suspect the Vehicle Speed Sensor
