Trans Temp Sensor In Line With Aux Cooler?

Looking to install a trans temp guage and wondering if it would be possible to remove existing sender on bottom of the aux cooler and install a T with the sender unit to the new (isspro) tran temp sensor?
I like the setup for the reasons well-described by RPegram in the thread, below, but was wondering if it would be possible to do this, as well. https://www.cumminsforum.com/forum/94...ml#post3191949
I like the idea of the sender in a oversized pan for the simplicity, but doesn't seem like that would be the hottest temps.
I know this is a topic that's been discussed ad naseum, but I wasn't able to find anything about this, specifically.
If anyone has any pictures or thoughts it would be incredibly helpful.
Thank you.

That would work, on my 97 I installed a drain plug in the stock pan to make it easier to drain the fluid. The plug is 1/8 npt same as my trans temp sensor so I used the sensor for the drain plug. Be sure to use a little Teflon tape to seal up the threads.

Underatood on that. I'd like to install in pan because it seems like the easiest, but my concern with that location is whether or not I will get an accurate reading of the fluid in the trasmission. I was wondering of I could use the existing sensor on the aux under bed cooler fan?
Doesn't the fluid go right there from the output line to tell the fan when to turn on?

When you buy aftermarket trans pans most will have a bung for a sender, there can't be more than a couple degrees difference.

As far as I know that auxiliary cooler isn't factory and look how far it is from the trans, the pan would be closer to actual temp.

Not sure what brand it is but it looks exactly like mine, I was told by P.O. that it was aftermarket.

If you think an oversized pan is a good place to put it that's all I need to hear. Makes it an easier job to boot. Thanks 9297oldram and myother4x4isaCJ7.

Mine's in my stock pan, but most aftermarket pans have the provision for the sensor.

I run a mag-hytech pan and love it, it is ready for a sensor too. With that aux cooler my temp never gets over 160-170 even towing way more than I should

I've been watching my trans temp with just a aftermarket cooler on the front of the intercooler and been staying about 120 to 140. Wouldn't mind finding a unit like you 2 have, all winter long it wouldn't go over 100.

Do you use the factory trans cooler that uses the engine coolant? I feel like thatís why mine stays at a solid 160, it gets to 160 real quick then stays there. I may remove it one of these days to eliminate a few leak points.

I deleted that about a year after getting the 97, now i'm running the one that the PO had on the Blazer when I got it. I didn't have a temp gauge on the 97 so I don't have anything to compare to.
