straycat, if it is the the solid brass then it won't blow out, some have a ceramic center, those are the ones that will blow out.
Although haveing it in the pressure port is the easiest, there is a time lapse of fluid getting hot and trans case getting hot. Sender in fluid, fluid gets hot, sender shows it. Sender in case, fluid gets hot then must heat up the case before you know the fluid is hot. I'll try to run the test this weekend and see the time lag. Preston
