They are not the same.
Go to your link above, DRIVE TRAIN, MAIN GEARCASE INTERNALS 2, Item #2

I would determine if it was broken wire in harness or dirty contacts in sensor before replacing a $178.00 assembly.

This may help.

The part number is 3234871.

I think your picture is of an 08 sensor.
The connector has 6 wires.

The 09-14 sensor connector has 2 wires.

I would check the continuity between the common (center) contact and high contact to verify internal resistor is bad.

If resistance is correct look for mechanical issue with pins, springs, & contact surface of sensor.
