Q: My car is a saturn vue 05. It starts will shift all gears. But it's not moving when I put into gear. Even in natural it won't move

Hi there. Let’s begin with the "N" position for the gear selector. That is neutral, or no direction meaning that the car does not move on its own power in that gear; only if you and possibly help from friends push the car. Do you actually feel the vehicle shift into a gear when the selector is placed in "D" or "R"? If not, this could an internal failure of the transmission; a clutch, band, etc.. no need to get into the technicalities of internal parts here. I would suggest having a qualified technician perform an inspection to avoid replacing unnecessary parts. Your Mechanic has several available technicians that can assist you with a car does not move inspection.
