My speedometer goes up to 35mph like it should and then starts going back to 0 when I am accelerating. ANybody have any suggestions about this problem??

 

Could be a bad connection somewhere. Look at the connector on the vss thats on the tranny. Maybe disconnect it and look for dirt in it or corrosion, clean it if so. The contacts on the connector for the gauge cluster may have oxidation, check that out. The vss itself may be bad but kind of doubt it. And lastly it could be a bad speedo.
