AWD 9 speed ATF coolers not available

Traded our 2016 CRV Touring for a 2018 Pilot Touring AWD so we could go camping again. Sales, ads, owner's manual state 3500 lb max towing wt unless you have AWD and Honda ATF cooler. Dealer confirmed we need the ATF cooler. But Out of Stock, no date of availability. Tried 2 more dealers - same story. We had eye on a 3500 dry wt camper and planned to limit it to 4000lb (5000lb - 20%). But no AFT coolers! After lots of research, we finally decided on a Flagstaff E-pro (2500 lb dry wt). We plan to limit it to 2800lb (3500 - 20%). We have 30k miles left on MFR drivetrain warranty, so we should be good. Pick up camper tomorrow. But....

Why can't Honda source these ATF coolers? I would like to add one as extra margin of safety and protect transmission.

Installed ScanGuage II to monitor transmission fluid temperature. Its running up to 150 F on grade (no trailer). How high should I allow the temp to go?

Does Honda have a 9 speed transmission warranty problem? I see lots of transmission issues on line, usually pervious generation.

FYI - e trailer does have an ATF cooler made by DERALE that the MFR says is compatible with the 2018 Pilot 9 speed transmission. Check the link https://www.etrailer.com/question-289171.htm
Technically any trans cooler is compatible. You could use this one, but you will need all the correct fittings to make it work. Good luck finding the correct fittings/pipes to get it done.

Dealer told me - can't remember which one - they only install parts they get from Honda.
Sadly this is mainly caused by the flood of counterfeit parts out there. There are a lot of parts available that are supposedly genuine Honda, in a Honda bag in a Honda box, but not actually Honda. If that part fails, most customers expect Honda/Dealer to stand behind it because they think it was a genuine Honda part, but it wasn't. Creates customer service nightmares, and in some cases, possibly legal responsibility issues for the dealer.

Gotta get a little creative when adding a BATC to the 9 speed tranny. I would think cutting the rubber tube section of ATF Hose A and ATF Hose B and simply clamping in two straight 3/8" hose barb fittings would allow for the installation of an aftermarket BATC with hose barb nipples. A little more creativity will be required to hang/mount the BATC itself.


This is the best solution.
Just cut the hoses.

Lack of supply is not a new thing.... 9 speed transmission cooler - aftermarket options? Someone at Honda or their supplier has had plenty of time to get things going.....

Aftermarket is just fine. I'd like to see Honda just try to reject a transmission warranty claim due to aftermarket cooler..

The only "catch" I can think of when adding any ATF cooler (even the Honda accessory cooler) is making sure to adjust the ATF level to account for the additional volume of the cooler and lines. If the 9-speed proves to be as sensitive to the fluid level as suggested by the service information, failing to adjust it could lead to damage that is not covered under warranty.

Example: Customer adds ATF cooler, but fails to adjust fluid level or lacks the required equipment and knowledge resulting in too much (or too little) fluid that causes damage to the transmission. Dealer notices an aftermarket or Honda accessory ATF cooler installed and finds incorrect fluid level with no signs of leaks. Honda denies warranty coverage by claiming that incorrect fluid level caused damage.

In reality, a few ounces off either way on ATF is probably inconsequential, but I wouldn't be willing to guarantee it. :)

I can't confirm there are rubber hose sections but it looks that way and if so, you only have to cut the rubber portion of ATF Hoses A & B (not Pipes A & B) and insert/splice in the hose barb fitting. The link says 2018 Pilot 9 speed. The later part of ATF Hoses A & B would not be used (discarded). The rubber hose that comes with the aftermarket cooler would be used in place of the discarded hoses in the Honda kit.

Yesterday received AFT cooler purchased from BKHonda.
Box says Genuine Honda Parts.
It's labeled
T.RAD North America 25500-5NC-0130
Product No: ACK5-00407
T.RAD No. C722-158-0002
Made in USA.


Is this a Genuine Honda Part?

It only contains the cooler - no fittings or pipes.

Also my previous conversations with dealers I believe I was told that the ATF kit included everything needed to install it?

So now what?

Are the fittings and pipes available from local auto parts suppliers or just from HONDA?

Do I have a solution or should I return it?

That does not look like the “kit” part number. See post #43, the 1st link.
