What kills transmission when tuning?

So it seems the auto transmission on the F250 pickups is the weak link in the whole formula. I see everyone stating almost as a rule you NEED gauges if you are going to tune. Makes sense, but it raises a question for me.

If someone buys a tuner what poses the biggest threat to the health of the transmission, the extra torque generated by the tuner or the extra heat generated in the transmission? Do most transmission failures come from too torque (twisting things) or does it come from too much heat (burning it up)?

Heat which is usually caused by your right foot most of the custom tuners have good shift points weak link in most 4r100 I have seen is the stock converter and make sure you tow in a tow setting not a economy setting shift points are different in a big way
