Let me start by saying I am new to the site as a user but have already made use of the site for references on a handful of questions. I purchased my Durango in February and unfortunately, as much as it hurts my pride to say, I was tricked by the dealer. What they said they would add on as a tow package was not specifically the Tow Package IV listed as an available package. So I have been piecing together the tow package on my own. I have the hitch, wiring, and full size spare. The next key thing I need is the transmission oil cooler. The dealer claims they are not available to order yet. So my questions are:
1. Has anyone installed a transmission oil cooler on a 2014 Durango? Or any year? 2. What is the best brand? 3. Is there a way to find the OEM product sold in the tow package without going through the dealer?

Thanks in advance for any help you can give.

I know this thread has gone a couple of weeks with no reply but maybe I can help as I was trying to find the same answers in June. If I'm not mistaken my "D" is the same as yours '14 SXT V6 w/o the tow package. I too have been trying to get my ducks in a row and get mine the tow package as close as to factory as possible. Anyway I'm sure you know by now that the trans cooler is incorporated into the a/c condenser. Now you could stick an aftermarket trans cooler, but if for whatever reason something goes wrong with your trans the warranty isn't going to cover it. If you want it to be like factory heavy duty cooling then you need to get the correct radiator and drain all the fluids etc... but there is no tranny cooler in the radiator. Hope this helps.

no, no, no.

No WD (or WK2 for that matter) leaves the factory with a trans cooler in the radiator. None.

So Tom do any Durango's or Jeeps leave the factory with an integral trans cooler in the radiator.
Just kidding.

Well thank you for clarifying that tom. I edit my post so there's no confusion for others that will look for this info.

the Tow package tranni cooler is a part of the AC condenser, its is in front of the radiator and the entire unit is split 70/30 with the lower portion being AC condenser and the top 30% being tranni cooler

"Supposedly" I have a dealer working on matching the factory tow package to 2014 3.6L V6 Limited as part of a purchase agreement. In an effort to keep them honest I have been learning more about engines than I thought I ever would.

Is there anything else to the Heavy Duty Cooling over the standard cooling than this trans cooler? Is there also something that has to be done to the radiator? Any other modifications? Sorry if these are dumb questions.

Well it depends on who you talk to. The dealer told me the cooler was not available for them to order. I have looked into aftermarket coolers but can't get a good answer on if it will void the warranty. I took a road trip from Maryland to north Dakota and took notes on the temperatures. After that trip I towed a 3000 pound camper into the hills of Pennsylvania and the temps never rose above what I had seen on my other trip. Not even the specialists at Dodge can give me a straight answer on what the improvement is supposed to be with the heavy duty cooler. So I hope you have each part of the tow package in writing on your purchase as I did not and have been working on it since i bought my Durango.

It was written up as the "Trailer Tow Package". The service guy is being pretty thorough understanding that my trailer is almost 6000lbs if fully loaded. Still nervous though.

So you were monitoring the engine temperature? Probably no way to monitor the transmission temperature?

If you look into the grill, you can see the ac condenser (infront of the radiator) has fatter plates on top. That's where the transmission cooling lines go in. If I'm not mistaken, all the durangos have the same set up. All automatic vehicles come with a similar trans cooling systems now. Some truck manufactures have a seperate core for trans cooling with their tow packages. The tow group IV has a larger radiator, full size spare tire, 7 and 4 pin wiring, and a class IV hitch.

I tow a 5000lb boat through the Cajon pass in Southern California durring the summer months. Outside temps are regularly over 100. My '12 Hemi R/T has the group IV tow package. It tows good. Not as good as a full size pick up though. My trans temp once reached 250+ while towing, the oil was 226. The very next trip my oil temp reached 249 and my trans temp didn't rise above 210.

Update-
I was at the dealer for a few hours negotiating the purchase of a '14 Citadel last week. I was looking over some '15 Citadel V6's with tow group and saw they now have a separate transmission oil cooler IN FRONT of the A/C condenser! The '14's still have the Trans oil cooler in the A/C condenser on top.

This setup costs more to manufacture, wich leads me to think chrysler engineering wants more cooling for the new 8 speed.
