Hello, I have a 98 1500 slt that the speedo is not working in. I recently bought it and the previous owner had no idea why it isnt working. I just took apart the rear diff to change oil and gasket there and the sensor there looked just fine. I have searched the forums and I cant find any answers. Thanks for your help it will be much appreciated!!!!

 

You mean the sensor tested fine or looks fine.. ?... they all look fine..
