In the morning when the motor is cool, the vehicle drives and is shifting good. When I shut down the engine and turn it on again, it looses the red light by the shifter, and the vehicle only goes on one gear, it is stuck on that gear. How do I fix this problem?

It sounds like you have an input shaft sensor that is going out, but to be sure lets run the codes to see what's going on. Please follow this guide.

Please run down this guide and report back.

Cheers, Ken

Hi Ken, thanks for responding. I went to multiple mechanics and they told me that the problem is the input shaft sensor. But nobody knew where the input shaft sensor is located for my vehicle. I already changed the output sensor, but I do not know where the input sensor is. Could you explain to me where it is or show pictures? Thanks.
