I have a Saturn Vue 2006 2.2L Engine...My Odometer/Speedometer does not work I keep getting the P0502 code and I REPLACED both Speed Sensor . Also Code U0101 TCM NOT communicating, Also I had the TRANSMISSION Speed Sensor Replaced as well. Can Anyone Tell me why it's still not working? FRUSTRATED

 

Probably the problem in your other post.

 

No need for two posts. Do you know how to use a meter?
