As I am researching how to add a temp gauge and sensor, I stumbled across this information at a off-road discussion group. It describes a couple of neat ways to set up the sending unit with and without an external filter.

one of the links to follow is this one:

one of the pictures (for a simple rubber hose sensor) requires registration to view, here it is in case you're interested:

What is your tow vehicle?

There will be a pressure and a return line to the cooler. You should be able to remove the pressure line at the transmission and add a "T" fitting where you can install the sending unit along with the pressure line for cooling. The pressure line should probably be the hottest temperature point.

I have a 2002 GMC Safari pulling a 93 16' Casita Spirit. I haven't installed the transmission temperature gauge yet. I do believe there may be an OBD2 code that feeds the transmission temperature as I've found the flashing "Service Engine Soon" (SES) light when going up hill in hot weather.

I would question cutting the rubber hose to add the sending unit. Oil leaks as well as heat are not good unless you have a deep pocket book.

The transmission on my vehicle has a plug in the side that is there for a servicing technician to temporarily install a pressure gage. It is used to measure the pump pressure. A gage sensor installed in this port will measure the fluid temperature as it exits the pump.

A transmission shop can identify the correct port and perhaps even sell and install the sensor for you.

As stated previously, knowing your tow vehicle year, make, and model would definitely

You might want to check this out, you can set it to display transmission tempatures of most vehicles
along with other neat information and all you have to do is plug it into your OBD2 or OBD II port.
