you should read 2 threads in the 1994 1/2 to 1997 7.3, the threads are “trans probe location” and “stacking trans coolers”

I think you should run 2 trans temp probes. In the hot tranny cooler line and the tranny pan, the pressure port is easy to do but it is a CASE reading, because the aluminum tranny case acts as a heat sink for the engine.

The first thing to get hot (generally) in an automatic is the torque converter, and the front tranny seal will tends to let go because the hot tranny fluid exiting the TC must pass by this seal, so If you monitor you Torque Converter Temp (TCT) and it gets hot 260* plus (I have seen 280*+) just stop what your doing let the truck idle in park till it cools. I wont shut my trucks down until the TCT is less than 190*ish.

I like to run an Engine Coolant Temp (ECT) gauge also, the factory ECT temp gague is to vague for me. I put my ECT probe in the thermostat housing

As for EGT I haul heavy with my trucks and I run in the 1300’s a lot, with the waste gate hooked up. The EGT dose run cooler with the “red” hose un hooked but it kills fuel mileage and power (to much back pressure) above 2400 rpm, but pulls much better at low rpms.
