    Bought an aftermarket transmission cooler for my 2005 Uplander. It is Fanned.

    I wanna put a relay in which can trip the fan to come on during a certain temperature.

    I found a cheaper one on eBay but I am seeking info to see where I must mount the sensor in the transmission?

    Thanks!

    I would mount the temp sender in a fitting on the outlet of the cooler as you are planning on running the coolers fan off of it
    can NOT speak to YOUR tranny but NORMALLY the cooler is plumbed to the torque converter return line which is the HOTTEST source fluid and the most likely to "spike" temp wise so using sump temp to trigger the fan that cools the TC oil returning to the tranny would be less accurate as you will not start the fan until EVERYTHING has heated up VS cooling the HOT oil BEFORE it reaches the sump

    if you are running a GAUGE on the dash the SUMP is a BETTER place as you see the operating temp NOT the spike temp

    Awesome reply.

    Here's some information I maybe should have included.
    This is the thermostat to be used:

    I assume that one needs a ground.

    One of the best options I can get. Mostly there for over-temperature protection. Otherwise I would use a 12v switch.

    Thanks!

    the ground is the fitting it is screwed into and it will SHORT the pin to ground ABOVE the temp and re open it below

    you would run a relay with this switch and the relay drives the fan motor
