Looked at that. all the nuts seem to be tight. There are three post on one side that have the three prong plug that fits on. Then there is another single post on the opposite side that does not have anything plug on. Any ideas? Also, i got a wiring diagram from the dealer and i traced the wiring back and i found a plug on the harness with the color code matching the back of the speed. Nothing is pluged in and the diagram shows a rotation sensor which is what i believe should be the device in the transmission. So, i think the dealer may not have installed the sensor. Could you snap a picture of the sensor so i know what i am not seeing.
