Had same issues a month after purchase. Got a brand new transmission installed under warranty. Some kind of defect and something metal broke off inside they said.

Based on dealer service tech findings, the problem was caused by 1/2 quart overfill of the transmission. No code update was outstanding for the TCU. On the short drive home I notices no transmission searching for gear in the slow speed range. (This overfill issue looks like a screw-up in the line and appears to be not uncommon since the service advisor pointed to this option right away after hearing the description of my observations)

Got a brand new 2020 Passport, and have a similar issue. I don't have the "random searching" issue, but do get an issue between 25mph-35mph where the transmission will do a "clunk". I see that when driving slowly. When accelerating fast, I never feel it. I see some discussions about this being normal on Ridgeline/Pilot with the dog clutch. Talked to the dealer, and said "don't worry the transmission is under warranty". Car has 200 miles on it...

Mitch2700,
We Have a similar issue, hard shift from 4th to 5th gear, approximately 35 mph. Took the car in and Honda said they couldn’t replicate the hard shift and everything checked out ok but noted on the account of the problem. Started around 5k miles and now have 15k and still doing it. Taking it back in again as it has not resolved itself.

Hi, did you get yours fixed?
I noticed my EX-L would do the same. I'd feel and hear that "kick" with that next higher gear engaging. Not sure yet on which gear exactly. But it's on the 2nd-3rd or 3rd-4th or the 4th to 5th gear switching. Also, It only happens on that specific gear, the other gears are ok.
This usually happens on those hotter days or when I drive in an unusual way, the non conservative way. I am guessing it is a thermal issue because I don't get this problem when driving on a cooler day or just cruising around on a cooler day.

This this the same as the thud I hear and feel at about 23- 25 MPH? I had my 2020 EXL PP in the dealership yesterday and they told me they couldn't reproduce it the issue. But they did (I hope fix the cracking Info system)

What you all may be experiencing is the engagement of the dog clutch. It engages at the 4-5 shift and disengages at the 7-8 shift. It should not be that noticeable though. I have approx 11,000 miles on my Touring and I have never noticed anything like this on the 4-5 shift under any driving conditions. I do, however, hear and feel a very slight "shudder" on the 7-8 shift which is easily replicated. This issue, as has been explained by Honda, is due to having the OEM transmission cooler installed. It is described as a "normal operation".
you might try taking off in S mode and using the paddle shifters to see if you can replicate the noise at the 4-5 shift.

Hello all,

So sometimes our passport (with around 5k miles) will shift pretty horribly around these speeds. It's mainly noticeable when coasting or slowing down around 28 mph or so. It seems to happen when downshifting. Sometimes you can feel it when it's shifting up around 35 mph as well, but it's not as bad. I haven't taken it in yet, but I'm not looking forward to having to replicate the issue when I do. Anyone experience this?

My 2020 PP elite with 300 miles shows transmission shifting up down while at constant low speed in range of 30mph.
This is just a soft but annoying shifting. It looks as if the dynamic range for the gears not properly overlapped. Any comments from the experts?

Same problem experienced today. 2020 PP Elite, 9950 miles on it. But also experience random electrical issues (clock displays 8pm Oct 29, 2015 more often than not, ambient lights not activating when headlights are on, reverse lights not turning on in reverse, display says to press brake to put the car in park. I look straight down at my foot on the brake). I took it to the dealership to hear there was a recall for some electrical component that was switched it. Two weeks later, I got the recall notice in the mail. Still experiencing issues and more. Any advice?

My car does it when shifting from 3rd into 2nd. It's more pronounced going downhill when slowing down. I think my situation is attributed to the design on the 9 speed tranny. Gears 1 and 2 are shifting differently than the rest.

Today I brought my PP into the Honda dealership for b16 service and mentioned the hard upshift about 35 mph and wanted the tcm updated...tsb#19-124. They called me back later after test drive and experienced the hard upshift but told me it was under tsb#20-029. They performed the update and the PP feels smoother right away.

Had the transmission software updated on my PP today with TSB 20-029. If you have a 2019 and experiencing hard shifts, contact your Honda service advisor and discuss the problem as well as TSB 20-029. The $100 diagnostic charge was waived since the TSB was applicable and covered under warranty.

Have a 2021 passport elite. And I’ve been have similar issues. Must be something with the 9 speed trans. Wondering if anyone knows about this is a normal issue with the trans.

I have the 2019 Honda Passport Touring and the transmission shifting drives me crazy!!! I have had it in twice and they can't get a handle on what is wrong with it. I have to keep doing my own research for them. Now my B7 light came on and they are making me replace the brake fluid! $159.
