Running after key off??

A quick addition of a relay, (I should have done it in the first place), solved the issue. Now I have a working transmission fluid cooler with fan. It starts at 180 on the outgoing from the transmission and even in 100% temps today it stayed at 170* F in the pan on a 20 minute cruise with a bit of 3/4 throttle acceleration up to 80 mph.

Thank you for the quick and helpful responses.
