monitoring tranny temp more important in a PT car or a drag car

[PT Sportwagon]

I have an Autometer tranny temp gauge that came out of my wrecked 95 Explorer. I never got it even hooked up. I am wondering if it is more important to monitor tranny temp in a Pro-touring car or in a drag car.
I am looking to put it in my PT wagon project or in my 89 street/drag car project. I already have ultra-lites in my wagon, and the temp gauge is a z series. Maybe I'll put it in my drag project along with the other z series watertemp gauge out of the explorer, Then get a ultra-lite tranny temp for the wagon to match.
