The ideal place to measure temps is where the oil comes from the torque
converter. That is going to be the hottest place you can easily get to to
install a sensor. My oil temp sensor, fitted into my Ragusa finned aluminum
pan rarely registers over 160° farenheit. So it never sees converter oil.
That goes to the cooler before it returns to the pan, so if you are having
a bunch of slippage and overheating, you will never see it on a gage. Guess
you could have more gages, in and out, etc. Somewhere there is a chart that
tells you the temps that various fluids can tolerate. If memory serves me
correctly, the synthetic transmission fluids can tolerate the most heat.
That is what I use in my Manny Tranny, along with fairly frequent oil
changes. Fluid is cheaper than transmission parts, by a whole bunch.
