Thank you. That's the main input shaft speed sensor. You are not going to locate this from under the hood. You need to lift the van up, its located on the top of the differential casingof the transmission. Locate the front drive axles under the van, they go into the differential casing. On the top/back of this casing is where this sensor is located and yes its a pain to get to. There is an electrical connector plugged into it that needs to be unplugged and then a 10mm bolt holds the sensor to the transmission. The o rings tend to seize to the case on these so you're probably going to have to pry the old sensor out.
