Location of the input and output sensor. A bit confused. I bought both input and output sensor from Autozone. I did replace the output sensor and the hard shifting went away but still speedometer acting up.

The speed sensor is on the transmission near the passenger side axle shaft output. Here is a diagram with red arrows showing its location Please let us know what happens. (BELOW) The input sensor is behind the side cover of the transmission. Attached below are the instructions and diagrams of how to replace it. Let us know if you need anything else.

1 - Pressure Control (PC) Solenoid Valve
2 - 1-2 Shift Solenoid (SS) Valve
3 - Automatic Transmission Input Shaft Speed (ISS) Sensor
4 - 2-3 Shift Solenoid (SS) Valve
5 - Automatic Transmission Internal Mode Switch (IMS)
6 - Vehicle Speed Sensor (VSS)
7 - Automatic Transmission Fluid Pressure (TFP) Manual Valve Position Switch
8 - Automatic Transmission Fluid Temperature (TFT)Sensor
9 - Torque Converter Clutch (TCC) Solenoid Valve

Check out the diagrams (Below). Please let us know if you need anything else to get the problem fixed.

Hi I have a question. So I have a 2008 3.9 l v6 impala and I bought a scanner tool that reads abs, connected it and showed code c0035 00 and pointed to the left driver side wheel speed sensor. Where is the 10 mm bolt and rest of the harness located? I have been searching for days now to find out where it is located.

There should be a wiring harness running to the sensor that is in the hub. If there is no harness there, then that is your issue. It should not take you days to find it so I imagine it has been tucked out of the way. Did this issue just happen or did you just buy this vehicle? I can understand if you can't find the speed sensor because that is kind of tucked up behind the rotor but the harness should be the only wiring harness on the entire assembly.

Here is all the info for the code and a picture of the harness and sensor. Let me know if you still can't find it. Thanks

Where is the input speed sensor located on this car? This is not the output speed sensor (VSS) which is on the passenger side of the trans-axle near the final drive. This is the input speed sensor that feeds the turbine speed to the ECM. Not for vehicle speed readout. Anyone know where that is? This car is the SS model.

Good morning.

The input speed sensor is in the valve body on the side of the transmission. The plate needs to be removed to gain access to the sensor. Picture attached. Check out the diagrams (Below). Please let us know if you need anything else to get the problem fixed.

Code p0722 is for signal from output speed speed sensor signal. That could explain your speedometer etc. I would take it back and complain could just be something unplugged.

DTC P0717 : Input Speed Sensor Circuit Low Voltage

If the input speed sensor was replaced then the wiring harness needs to be inspected. Ensure it is not stretched too tightly and also that other components are not pressing on the AT inline 20-way connector body. Also inspect for proper clearance to any other components and wiring in that area.

After looking at your title it looks like you are looking for the vehicle speed sensor. This picture is for the 3.8 engine since you did not supply an engine size.
