The line that you have labeled at the ATF loop is where you would tap into for the external cooler. Much like the hayden that was mentioned early in the thread.

I know how to add one. What I want to know is if this is the setup for the 3500lb rating. Seems like it is

Yes. Vikefan has the towing package, though, and says his looks exactly the same. Thus my confusion.
And mine. I swear I have the towing package. I'll take a pic to prove it....
Okay, here they are. Sorry it took so long, had to find the right camera to take these pics. I've included a picture of the atf pump that you requested as well as a picture proving that I have the stock towing package and a view looking up from underneath the car just behind the radiator.
Hope this helps.

And you already confirmed that there isn't a third cooler in front of the radiator, based on my photos, correct?
Yours looks almost exactly like mine. The connector at the left fan is different.
Can you take a photo looking at the fans from the prop rod, and straight down on the left fan, like these?:

vikefan7,
The "thing" with "heat-sink" is the "fan control module" (based on WorkShop Manual).
Denso is a big company in Japan. Their product line covers many areas.
On Tow Package, there are two fan control modules, on regular CX9 (like mine), there is only one. The WorkShop manual also mentions this. However, it only mentions that some models have dual fan control modules. From comparing yours and mine, I think it is the Tow Package which makes the difference. Strange though, mine also have two fans controlled by one module. On Tow package, there are two control modules control two fans. More efficient? "Heavy-duty"? Who knows?
I also found something interesting (I believe someone asked about this), and I quote:
"Depending on the vehicle, the cooling fan may operate suddenly even when the ignition switch is turned off. Therefore, keep hands and tools away from the cooling fan even if the cooling fan is not operating to prevent injury to personnel or damage to the cooling fan. Always disconnect the negative battery cable when servicing the cooling fan or parts near the cooling fan."
So, our beloved cooling fans do activate even when the ignition is off.
Case closed.

The fan control modules are definitely different. I don't even have one on the passenger side fan, so that is the difference, not the ATF cooler itself. ('heavy-duty transmission cooler and radiator fan').
I will still need to add a front cooler to get more than 1500lbs. (Or replace the internal loop with the auxiliary cooler) At least now I know, and how to hook it up. Thanks for your help, vike.
Ceric, do you have any insight on the 'revised Engine Control Module'? Is it shift points, or temp sensing?

It will be a while, since right now I don't need the 3500lb rating yet.
If anyone else out there installs one, go ahead and post your photos for anyone else interested.
When I do, I was thinking of bypassing the internal cooler by disconnecting and extending the lines on the bottom reservoir to go to the new cooler. Then cap off the original connections so the whole thing can be reversed.
