Just in case someone's interested just got home from driving around in town taking care of some business and the outside temp was 73 and my trans temp was staying around 165 degrees. Which is cooler than if it was running through the factory engine cooler if it was still on.

Are you referring to the OE temp sensor that is going into/on the aux cooler? It appears that's the next stop for the fluid from the output line of the trans, so it should be a pretty accurate reading(?). If so, that's where I imagined (trying to) put the aftermarket sensor to replace the original, and read fluid temp from. Then, I would put a manually-operated switch inside the cab so I could turn the fan on when temps start climbing. Or, is the OE sensor you're referring to located elsewhere?

To be honest, I'd ultimately like two sensors: one reading the hottest temps possible, and another in the pan. Since I don't have a deep pan with the allowance for a sensor yet I'm trying for the former. Then, after a deep pan is installed, I'd also be able to tell the effect of the increased fluid capacity.

Not trying to beat this into the ground, but would like to be clear on all the options. Im far behind everyone on this thread wrt technical knowledge and so I appreciate all of your time, patience and consideration.

You don't need a deep pan to be able to have a sensor, if you look at my post no 2 on the first page I told you how to put one in the stock pan.

I assumed the sensor wouldn't have enough clearance from the filter when using the stock pan. You're saying your sensor does not interfere with the filter?

The sensor is no where near the filter it's in a corner of the pan in a spot that is low. Also if you want a temp gauge in the hot line why not go with this https://www.genosgarage.com/product/.../gauge-related . Then you can keep your fan so it comes on like it's supposed to, if you want your fan to come on sooner then get a lower temp sender for it.
