Ok so I have a 1999 Dodge Dakota 2WD auto with the 3.9L V6. I have two error codes, P0420 and P0720, the 420 is for the cat converter and im not to worried about that cause i my friends dad can fix it. my question is about the 720. its the output speed sensor and from what ive read it seems easy enough to fix it myself and i think ive found the part i need for it

but im not sure if i need the speed sensor for the transaxle or the one for the rear differential. i dont know how to find this out so any help would be appreciated. i dont want to buy and fix something if its the wrong thing

 

anybody?

 

The one on the tranny is the output speed sensor. (P0720) Just like the one in your picture.

The one on the differential is the vehicle speed sensor (P0500)

 

ok cool that means i bought the right part lol
