I'm trying to find out where the location is to my input/output Transmission Speed Sensor on the car listed above? Once I start the car and put it in gear the car doesn't move..

Hi,

The input speed sensor is located on the valve body inside the transmission. You will have to remove the oil pan cover on the side of the transmission to access it. If you look at the first five pics below, they are the directions/pics specific to your vehicle for replacement,

The output speed sensor is located on the outside of the transmission near the left axle. If you look at the remaining pics, they include the directions/pics specific to your vehicle for replacing the output speed sensor.

I hope this helps. Let me know if you have other questions.

Take care,
Joe
