Transmission cooler necessary for Jeep Grand Cherokee?

I am interested in getting a 4WD 2014/2015 Jeep Grand Cherokee Limited with the 3.6L V6 to pull a 19' Escape (TWR is 6,200lbs). According to published specs, the Grand Cherokee standard rear suspension includes load-leveling for towing. I estimate the loaded weight on the trailer, including options, will be no more than 4200lbs.

Has anyone who is towing a similar weight with this vehicle found it necessary to add a transmission cooler and or an engine oil cooler?

For me,if you are towing , one should have a transmission cooler saves the tranny . Nothing worse than being stranded out somewhere with a dead transmission. Seen dozen of times. But that just me.

I am in 100% agreement. Started with an aftermarket unit my 1970 Ford pickup and have had either aftermarket or factory installed ever since. I’m a believer. Do not have a scangauge but think they are good too.

We towed our 2016 Escape 19 from Chilliwack to Calgary through the mountains of Washington State with our Jeep Grand Cherokee V6, The Jeep performed well and had no issues. The towing capacity is 6200 pounds. No additional oil or transmission cooling was needed.

You should have a transmission fluid cooler, and the vehicle comes with one from the factory... that's one reason that it has that tow rating.

You could monitor transmission fluid temperature, and add more cooling capacity in the unlikely event that the fluid is running too hot.

I appreciate the feedback. I was initially under the impression that you could tow up to 6,200 lbs without the factory tow package (per info listed in the 2014 and 2015 Trailer Life Tow Guide). However, upon closer scrutiny this is not the case.

The 2014/2015 Jeep Grand Cherokee Trailer Tow Group IV option includes Quadra-Lift Air Suspension, heavy-duty engine cooling, Class IV receiver hitch, 4- and 7-pin wiring harness, rear load-leveling suspension and full-size spare tire; it deletes the rear tow hook

I also found a Jeep web site where you can run the VIN and get the factory build sheet for the specific vehicle.

https://www.jeep.com/webselfservice/...527R%2527%2529

Look on the left, under the section entitled "YOUR VEHICLE" and click on "Equipment Listing".

When you enter the VIN, the system will generate a build sheet in PDF format. Very helpful when shopping used vehicles!

Thanks to all for the feedback. I responded earlier today but my reply included links and I guess those have to be approved by the moderator.

Anyway, I had been under the impression that the JGC were OK for towing up to 6,200lbs even if they did not have the tow package (based on info I got from the 2014 Trailer LifeTow Guide). That's why I was asking about adding a cooler. Upon closer scrutiny, I discovered that the Trailer Tow Group IV is required. This package comes with Quadra-Lift Air Suspension, heavy-duty engine cooling, Class IV receiver hitch, 4- and 7-pin wiring harness, rear load-leveling suspension and full-size spare tire; it deletes the rear tow hook. This tow package is an option on all but the Overland 4x4, for which it is apparently standard.

The JGC with the tp is one towing beast! I’m lusting after the diesel.
