Were to put temp sending unit on 700R4?

[Steve F.]

I just bought a used supost to be built for towing 700R4 for my 90 K5 & it will be used for towing & snowplowing.I do have a 6 pass tranny cooler w/the line going straight to it & by-passing the radiator.
I want to make sure I do not run this tranny HOT so Im putting a electrical temp gage on it.Do I have to put the sending unit in the pan, & if so were at ,or is there some were to screw it into, on the tranny.

Is it even built to tow.Here is what the reciept says:

The trans temp gauge that i got says to put the sensor in the trans pan.

trans line:

Upper - Return/in

Lower - Cooler feed/out

Search for this topic - it comes up every few months and there are a few different opinions on where the sender can and should go.

FWIW mine is in the pan which is my preference since it tells you the temp of the fluid before it is picked up.

the pan is the best place, but kind of a pain to install. for a quick and easy place, use the pressure port. its an 1/8" NPT plug above the shift linkage. sensor will screw right in. it will read a little hotter than a pan sensor, but you will still be able to keep track of whats going on.
