Both input and output speedsensors are located on the left side of the transaxle. The input speed sensor senses the turbine input by torque converter revolutions(slots on converter housing). The output sensor is mounted in-line behind the input sensor and senses the output shaft by the rear planetary carrier gear tabs. The same gear tabs are used to apply the park pawl, and thus lock the output shaft, preventing movement of the vehicle.
If you open the hood, the are located midway in-line on thr trans. One has course threads and the other has fine threads so they can't be mixed up. Same size wrench is used. Watch for bad connectors on these sensors.

The input sensor is just below the cooler lines on the transmission to sense the spinning input clutch retainer thus sensing the input shaft. 12 inches back is the output sensor. Ok I am tired.
