I decided to move the sensor from the front trans line to the return line after the radiator and aux cooler. (If I get my new pan this Winter I will move the sensor to the pan.)

After running it all weekend I now know that my radiator and 14x10 aux cooler cools the fluid down from 205ish (front line) during hard driving to 180 during hard driving. I run a 195 thermostat so the trans fluid looks to be in a safe temp zone.
I just wanted to let others know the difference between the fluid temps from the front line to the return line and I am now using a 3800 convertor and a standard depth trans pan.
Do you think that I still need to look into a deep pan when the fluid temps are in the 180 range after hard street driving?

Thanks
