Hi,
The temperature sensor is inside the transmission. Accessing it requires the draining of the fluid and the removal of both the filter and valve body.
If you look below, I attached the directions from my manual. Take a look through them and let me know if you have any questions or if I can help in any way.
Take care,
Joe
