Where is the speed sensor located in a 1996 Aurora?

their are two different speed sensors on that car the input speed sensor which is located inside the transmission and the transmission needs to be removed in order to replace it and the other speed sensor is the output speed sensor which is located directly above the passenger side trans-axle shaft. your input sensor is the sensor which tells the transmission when to shift and the output speed sensor tells the speedometer what it should display and both those parts are fairly cheap they are around 15-25 dollars but just remember if your input speed sensor is bad it is gonna cost you a minimum of 1000 dollars to have a mechanic fix it because of the fact that the transmission needs to be removed.
