The car has been in limp mode I’m assuming it’s because of my speed sensor. Just need to know where the Auto Trans Speed Sensor is located on the car listed above 300c. Couldn’t find any videos on it.

Hi,

The transmission has both an input and output speed sensor. I attached a pic below of the transmission and highlighted the output speed sensor.

Before you buy one and install it, you may want to have the CAN system scanned for diagnostic trouble codes. It will help confirm if that is the issue.

Here is a link that explains how it's done:

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

Take care,

Joe
