Hey all, I'm new to the forum, would appreciate any thoughts or advice on my situation.

I have a 3,000lb trailer I need to tow. I also have a relatively small garage and prefer smaller vehicles. I did a bunch of research on my options and was excited when I found the Passport - a relatively compact SUV with a 5,000lb tow rating. Perfect!

I went and spoke to the dealer (I am in Seattle) and triple-confirmed the tow rating with the salespeople (this is important given what happens later!), test drove a 2022 trailsport and liked it. Bought it with tow package.

Great! I thought, problem solved!

But, when I went back to the dealer get the tow hitch actually installed, the Honda tech mentioned a "3,500lb tow rating". I was like "hold up, what was that?" He explained that the 5,000lb rating required an optional transmission cooler. The salespeople neglected to mention that, and I made the mistake of assuming the "tow package" included everything necessary to reach the rating (which is featured very prominently in the marketing material). As a result I bought a vehicle with a 3,500lb tow rating, believing it had a 5,000lb tow rating.

So I said "OK, well, can you install the transmission cooler for me?" and that's where the real problem starts - this part (06255-5EZ-317) is unavailable and backordered in the entire US. The dealer can't get one. I can't get one online (e.g., it's listed on hondazoneparts.com, and I was able to place an order, but they canceled it next day saying it's backordered).

So... as things stand I'm a bit screwed. My 5,000lb tow vehicle can only tow 3,500lb, and that's not sufficient for my trailer.

Anyone got ideas for how to source the part?

The only other option I see is to sell the 2022, and find a 2019-2021. The transmission cooler for those (06255-5EZ-316) is widely available. So if I go back a model year or two, I should be able to have the compact 5,000lb tow vehicle I was originally after. Which will be a giant pain in the ass, and likely lose me some $$$ in the process, but I'm not seeing many other options...

Oh I should mention, I went to a local transmission specialist to see if I could go with a fully aftermarket/non-OEM transmission cooler. Unfortunately that route seems blocked as well. They took a good look and said they weren't confident about how to install one on the 22 passport, it wasn't a "routine" install. Maybe they could figure it out, but I'd be paying unknown labor costs for them to experiment! Not what I'm after, I'd much prefer factory/OEM anyway, and I don't want to haul my trailer with an "experimental" cooler setup.

This is when you have to pick up the phone and call all of the parts depart. you can and have them share with you if one number on this part number makes a difference. The fact they didn't share with you about the 5k towing sucks! , but I want to help you find your part and so you can enjoy your PP!

When I bought my 2022 MDX it's transmission cooler was back ordered as well. It took 2-3 months to come in. You said your trailer is 3000lbs and the PP has a 3500lbs towing capacity with just the hitch, so your covered, maybe. But other things to consider are things like, what are you hauling? What kind of wind drag does it have. How far do you haul it? Tongue weight? A big ole boxy travel trailer of the same weight as a boat might haul totally different. So think about other factors vs just weight. You're covered by the 3500lbs but I also would want the oil cooler for more capability.

Thanks for the replies!

Looks like I might be able to get the 316 part to fit after all, so we may have a path forward after all. Fingers crossed. Will know more next week.

The trailer is 2800lbs dry weight, 3600 fully loaded (with water, supplies, etc.) although I will try to travel lighter than that. It's a teardrop so not too bad on the drag front. But I do plan to take some long (multi-day) trips in the summer, so I need to have a bit of headroom. I also gotta factor in cargo and people in vehicle.

GVWR for the 2022 passport is 6019lbs, tongue weight of the trailer will be ~350, add a couple of people and their stuff we're getting close to the limit!

Have you gotten an explanation between the difference in the new 06255-5EZ-317 and old part 06255-5EZ-316? Wonder what is different between the two parts and why Honda is changing their cooler? The older version has been sold for several model years and now they're changing it. I know they've changed the front end on the 2022 but not any of the engine and components.

Any Honda Tech. out there know the difference? Or issues with older version?

Thanks for any replies.

Don't sell your Trailsport. If your warranty expires before the back log is cleared, you can install an after market cooler.
Salespeople are smart and know better than to lose a commission, by looking out for the buyer.

OK update... turns out the part I had fit after all... it's all installed and working. The individual part numbers are identical even though the box they come in ends in 17 not 16. So for anyone in a similar situation, seems like the 16 part is a solution.

What a relief! That was a pain in the butt.

Getting brake controller installed as I type this, next stop transmission temp monitor.

Anyone got tips for temp ranges to stay within? How hot is too hot?

Excellent! The Passport already has the brake control wiring under the dash. Get a Prodigy controller and the specific wiring harness for the Passport and it's just plug & play.

The hottest my tranny got while pulling my trailer uphill was about 190 something.

Turns out the widely-available 06255-5EZ-316 part fit after all. It's installed and working happily. I also got a Scan Gauge II and set it up to monitor transmission temp in real time. I do my first test tow tomorrow (this will be with unladen trailer) just to get a feel for things.

Did my first test drive this afternoon, went great! This was hauling the unladen trailer (~2800lbs), Passport didn't break a sweat. Plenty of power to accelerate up steep hills, transmission temp stayed below 160 at all times as measured by a ScanGauge II (thanks to this forum for putting me onto that... really great device). I'll be adding ~1,000lbs for "real" trips, but based on this test run I think I'll be fine.

Details:

  • 2022 PP Trailsport
  • Factory tow package (hitch and harness)
  • Factory ATF cooler (for 5,000lb tow rating)
  • Primus IQ brake controller
  • ScanGauge II (for real-time ATF temp monitoring)
  • Basic hitch (this is where I'll do some more experimenting, might want a weight distribution hitch if I can find a good one <100lbs... you can see front suspension is lifting in pics...)

Loving the Passport so far, what a great vehicle!

Awesome setup! Some sumo springs should help the sag in the rear and super easy to install.
