Wiring harness that goes into the trans from the side has all the solenoid connectors plus a single wire to a small sensor.. Must drop pan ,,disconnect the connector plugs,, drop valve body and filter,, turn over and you'll see that all wires go to the solenoids except for one that is the temp sensor. The transmission cooler built into the radiator does not have the capacity to keep your fluid cool.. get a aftermarket cooler. You can not get the temp sensor except by taking one off of another harness since the harness is no longer available thru Nissan...
