I put mine in the trans cooler line going from the trans to the cooler. May not be te best spot, but I like it there.

The pan is the best place. You want to know sump temps. Putting the sensor in the cooler line to the cooler tells you nothing about how the cooler did its work.

If you are talking about the Allison, it is part of the pressure switch manifold bolted to the valve body inside the trans pan.

I put mine in the output line going to the cooler. I see the maximum temps that the oil is experiencing. That's what I really need to know, how hot the oil getting.

Yup, me too. Seems to be a minority opinion. Must be a VA thing.

Thanks for the information, Mike. One more question, where is the sensor for the temperature on a scanner? I would assume the same place, but like to hear it from an expert.

My scanner reading is almost always lower then my gage reading (which is on the hot line to the cooler), especially under load.
