So from what I have read you guys came off the bottom of the factory rad/trans cooler and went into the secondary cooler then back to trans line. Correct. So the top line going into the rad is where the hottest fluid would befor a trans temp sensor. Please correct me if I am wrong.
Thanks,
That's where I'd put a temp sending unit for a gauge, on the line flowing TO the cooler which seems to be the top line (it was on my '07 V6).
