No, I needed a new serpentine belt for inspection and my husband changed it for me and then the transmission won't shift and the speedometer doesn't work.

there is a sensor below the area where the belt is located on the passenger side. if that is disconnected, then it will cause problems. have him use a flashlight and look around. it is a 2 wire sensor.
