Hello, getting a P0720 code on a 97 Dakota. I assume this is the transmission speed sensor?

Can someone please tell me the correct sensor I need to replace. I’m confused because there are two YouTube howto videos showing two different sensors.

This is the part I think I need...

Dorman 917-602 Transmission Speed Sensor on Amazon. Notice this has threads at the end of the sensor.

But the following YouTube video is showing a completely different sensor, this has no threads, it just pops in. granted the error code in the video is also different ...

Is the sensor in the video different from what I need?

If the Dorman 917-602 on Amazon is the actual part I need, where is it located?

 

Looks like the correct sensor.

 

I replaced it and all good now! I did NOT use the one in the video, I used the one in the Amazon link.
