I have a P0721 code, and I want to change the output speed sensor. How do I find the location of this sensor?

Hi,

The sensor is located on the side of the transmission housing. If you look at pic 1 below, I highlighted the one you are looking for.

The remaining pictures are the directions for the removal and replacement. It really is a simple job. The sensor is held in by one bolt. It's been a while, but I believe it is a 10mm bolt. What I do recommend is that you clean the area where the sensor is removed prior to installing the new sensor. Make sure where it pushes into the housing is clean. Also, lubricate the o-ring with ATF prior to installing it to prevent damage.

Let me know if this helps or if you have other questions.

Take care,

Joe
