2006 CrownVic, Cop car.
The electric cooling fan seemed to be running on high speed (almost) all the time. By the time I saw it, the control had been replaced, the fan assy and pigtail had been replaced. No check engine light, but it did have a transmission code relating to overtemp.(sorry didn't make a note of it). After much testing, and several phone calls, decided to replace the A/C condenser.


Why the A/C condenser you ask?
Well, because the bottom 5" of the A/C condenser is actually a transmission cooler. As you can see, there are separate connections for the A/C lines at the top, and the ATF lines at the bottom. But more importantly, the ATF cooler has a secret that most folks do not know about. It has a thermostat built in.


This thermostat is not serviceable, so if there is any type of flow issue with the ATF, you must replace the A/C condenser.
So I did.
And it worked perfectly!

Electro... I'm smiling for you :)

That deserves a great pat on the back, and a half gallon of ice cream!
