Yes, ideally. That is where I fitted my temperature sensor for the MadMan EMS. You can see in the picture that you put on that there are three plug bungs between the two '26' pipes. I removed one of those and fitted it in there - I got lucky the first time and it was in the oil outflow from the TC.

IMHO unless you tow 3 tonnes in the desert across sand hills a transmission temperature gauge is just another distraction.
I have towed my 800-1000 Kg camper trailer on Stockton with my RRC in low range keeping over 2000RPM stall in very dry sand , and no red light and it didn't have lockup in third..

To be sure I use Castrol Transmax Z which has a higher oxidization temperature and is blurbed to reduce transmission oil temperature by 20C.

My theory is that by locking my TD5 trans as much as possible by changing down early on hills and using Transmax Z I am giving my transmission the best chance to survive. I am busy enough looking at my EGT gauge, my boost gauge and my digital engine temperature gauge let alone the GPS and speedo to check speed.

If you tow BIG stuff then go for it, and then you probably need a bigger oil cooler.

I must say I sort of changed my thinking about buying a bigger cooler after considering over cooling . I recall I once had an oil cooler on a 77 RRC and it overcooled the engine and gunked up the breather pipes so much I had to drill the crap out of the stubs on the carbys. I added a thermostat which helped but then the bloody oil pressure would go away for a second as the thermostat opened.

If you fitted a thermostat to the cooler I think you would run that risk which would possibly damage the transmission.

My ems temp fitting is in the exact same bung

The problem still exists - the ATF cooler in that location still fills up with mud and dirt which blocks the airflow and prevents any cooling. It wouldn't matter if it was standard capacity or 10x the capacity.

any chance of marking exactly which bung?

How bout a photo (when the frost goes)?

frost? so thats a cold thing,, right?
Beautiful one day---

Bastard !

As my location title says.....

It's just taking longer than I planned.
