99 or comparable year automatic transmission LS. I need to have a pic of this to aid me in replacing the main driveshaft speed sensor. Need to get a feel for where exactly it is so I don't replace the wrong sensor etc... I was told its right in front under the hood 2 sensors, one is the countershaft sensor and the one to the right of it is supposedly the maindriveshaft sensor.... Can anyone confirm this or better yet email me a picture or diagram of the auto trans pointing to exactly where the main driveshaft speed sensor is??
