That was a question I had asked a few other people about the sensor. should it tell me how hot my fluid is before cooling or after. The torque converter has a 1200 rpm stall and is brand new. I will install the sensor on the inbound side and see if I can get a better result. Unfortunatly I ordered the tranny and converter from out of state so to take it in for them to check is going to be tuff. so basically the converter will be more of my problem then the tranny pump for heating issues. I do not have 10 miles on this system since I installed it. Thanks for the response
