I am looking for a diagram with the location of the transmission temperature sensor on my vehicle? The sensor became unhooked while replacing pressure switch and I do not see where the TTP is suppose to be. Any help would be much appreciated.

The transmission fluid temperature sensor is under the side cover.

Here is a diagram (below) of its location:

Remove the case side cover.
Remove the wiring harness assembly from the fluid temperature sensor (391).
Remove the fluid temperature sensor (391).
