I would also suspect them to be different because of the different final drives. So I would make the assumption that you want the vss gear to correlate with the final drive that you have.

VSS has nothing to do with final drive. Not on the models where the speedo drive gear is on the diff. It turns at wheel speed, so changing the final drive does not alter the accuracy of the speed detected.

If you have the same exact setup. Meaning wheels tires trans. One with a 4.4 FD and one with a 4.7. Your telling me that VSS will accurately display the speed of the car?

Correct me if I'm wrong but...

The VSS whether it is located on the diff or the counter shaft, reads rpm. It then sends a signal to the cluster of your speed. If your FD is 4.4 or 4.7 it will result in different rpms sending to your cluster. It may send the same speed, but your actual speed will be off.

If i'm wrong explain to me how a 4.4 and a 4.7 FD will yield accurate speeds shown on the cluster vs actual speed.

Do you have access to a GPS to compare speeds?

I'm curious if there is a speed difference.

Possible to check and compare?
