I have a 2011 mdx with 152k miles on it.
Serviced regularly, timing belt change, etc...
The car runs great.

I pull a 20' pontoon occasionally, about 10 times per year, gross weight with trailer is about 3,300 lbs. So not hitting the 5k max towing capacity.
We just took a fishing trip that required pulling the boat through the Ozarks.

I manually shift gears while towing to help tow the boat up hills...hit 4k RPM sometimes. This car pulls the boat pretty well, just can't go too fast and often am traveling below speed limit not to stress the car too much.

I absolutely love this mdx, and have no need for a 2019 or 2020 mdx.
However, I am considering selling the mdx and getting a full size truck since it would make more sense pulling the boat.

If decide to keep the mdx, any recommendations on what I should do to make sure the car is able to keep up with towing the boat?
New/heavy duty transmission is an option, but I think at thst cost it makes more sense to sell and get a truck.

I tow an 18" aluminum fishing boat with my 2007 MDX. Weight is probably around 2500 lbs.

I've installed a dedicated Hayden transmission cooler as well as a Scangauge ODB computer to monitor the transmission fluid temperatures. Highly recommend these upgrades.

If you installed a factory hitch, you probably already have an additional tranny cooler, but perhaps you can think of upgrading the coolers (especially if you never changed a radiator, which means it's about to fail on you any minute now given the car is 9yo. It's best to do that as a preventative measure before you get a chance to ruin your transmission by mixing in coolant and ATF.

There is no heavy duty transmission for the MDX to my knowledge. And a new one will cost a fortune, it's not worth it.

+1 for no heavier transmission available. More cooling capacity will do wonders for transmission life though and that is pretty cheap, as in less than $100 for DIY. That and fresh fluid annually.

I thought the issues with mixing ATF and coolant came on earlier models? What were the year models affected?

Early 2G= 2007-2009 were the most affected.. Its not a known issue on the Facelift 2G, Those have the much more dreaded Oil Consumption issues which didn´t affect the Early 2G.

Any upgrades to help with tbe towing...transmission cooler?

 

[StevenNdebbie]

Extra transmission cooler came standard for that model year, not as an option. Also engine was a 3.7L 300 hp V6. 6 speed. With the third generation Acura responded to the truck towing market by making it an option and going to the 3.5L 9 speed. Unfortunate on my opinion. Original towing tests performed towing 5000 lbs in Death Valley with 120 degree temps.

This is my account from a few years ago...could not find the credentials...

I am leaning towards keeping the MDX and replacing the radiator and transmission cooler.

Hayden seems to be a common choice for the MDX.
Any particular size recommended - Hayden 679 or 678?
Hayden is around $50 while OEM is a little less than $200.
Is the Hayden a better option over OEM?

This looks like quite the setup for towing:

Installing ATF and PS cooler for towing

I'm in the middle of installing the automatic transmission fluid cooler and power steering fluid cooler for towing. I chose Hayden 676 for the PS and Hayden 679 for the ATF. I'm putting Magnefine magnetic filters on both as I install everything. The coolers came with 11/32" ATF hose. This is...
