Is Transmission Cooler Needed to Tow 2500 Lb Trailer With 2011 Honda Odyssey  


I want to add a receiver hitch on my 2011 Honda Odyssey. I would be pulling a single axle 14 trailer, carrying a Honda Pioneer 1000, so totally loaded, about 2500+ pounds. Never more than 2 occupants when towing. Most trips less than 100 miles one way, and mostly flatland driving. Do I need to be concerned about adding a tranny cooler


Expert Reply:

From my research, I found that the 2011 Honda Odyssey has a 3500 lb towing capacity, so it will be able to handle the trailer and load you describe.

You might be fine without a transmission cooler for shorter trips on flat terrain, but I'd honestly suggest going with a cooler anyway, especially as the owner's manual recommends adding one to achieve the 3500 lb towing capacity. A cooler like # D13503 would provide extra protection for your transmission. The cooler doesn't cost much and the installation is pretty straightforward as shown in the linked install video.

For a hitch, I'd recommend the Curt Class IIl Hitch, part # C13068. You'll also need a trailer wiring harness such as part # 118521, a ball mount like # D-28 and a # PC3 hitch pin and # 19260 for a 1-7/8 inch trailer ball or # 63845 for a 2 inch ball.

I've also linked to install videos for the hitch and the trailer wiring harness.
