We purchased a 2017 Pilot EX-L new and have loved it. We’ve babied this thing (our first new car) and it’s been to the dealer every 7k for oil and checkup.

I hopped in our Pilot on Friday and within a minute of driving noticed the trans was slipping for 1-1.5 seconds and then shifting hard.

It didn’t matter how little or much gas I gave it, kept slipping for probably 20% of it’s shifts. I immediately called the dealer and headed in. It continued on the freeway on the way to the dealer.

Dropped it off, they flushed the trans and did software upgrades and the tech told me the fluid was black. Not a good thing at under 20k.

I was told to take it home and let them know if there were further problems. On my way home (under 5miles) the trans slipped worse than before, this time for up to three seconds and then banged very hard into gear (I let off the gas as soon as it started to slip).

It continued this the entire way home. It also threw a trans and emissions code error on the way home. Called the dealer, dropped it off this morning. They said they’d look at it.

Any advice for me? We’re not exactly wealthy and purchased a Pilot because we wanted something reliable, but this has been a terrible experience thus far. I’m worried that we’ll have major problems down the road and I’ll be faced with huge repairs. Thank you for any input you can provide.

That's very unusual. Assume you are under warranty. So let the dealer handle

I had the transmission replaced in my previous '16 Pilot EX-L at 10,000 kms and it was completely fine after. It was actually replaced at the same time as the first oil change.

Tell them to change or check transmission fluid pressure sensor.

Thanks for the info Puffin! That makes me feel better. How many KM have you driven it since?

It sounds like they are replacing the entire transmission. I'll let them know to change the transmission fluid pressure sensor as well. Thank you for the info Alexz!

I assume this is the ZF 9 speed transmission?

Nope. ExL has the six speed. It's been Honda's go to for ten years now. They've probably built millions and millions of them and failures are very very rare.

I’m having some issues on my 18 EXL. Sometimes takes to long to switch gears when going from reverse to drive and if i don’t pay attention and hit the gas after switching it clucks when taking off. and I’m always very careful to wait a few seconds for it switch. lately gets a little clunky when taking off from a light or stop sign from a full stop or slips as your were experiencing and the new one that has started about 2 to 3 weeks ago when going up a hill or even small incline foot steady on the pedal and mph not changing the RPMs will fluctuate and I can feel the car bucking slightly as it does it. its only a small amount. If Im at 1500 RPM it will probably street doing it between 200 to 500 rpm up and down for a few seconds. And it did do it once on a level surface. How fast I’m going doesnt matter. and so far have noticed it between 1000 and 2500 RPM

Going to do a full flush this summer myself and see if that helps. haven’t checked the fluid yet going to do that today.

Give us an update on what happens.
They replaced the transmission. Problem is now there is a noise, and a corresponding vibration that was never there before and that I don't trust moving forward. It's extremely noticeable from 30mph on up. For the most part the noise gets drowned out by road noise on the freeway but the vibration is still present. It does appear to be rotational and potentially outside the trans itself. I haven't taken a look at schematics or how this car is laid out. The noise doesn't change with gear shifts, it just gets progressively louder the faster the car moves. I'd guess some sort of output bearing or joint from the trans to the hubs/wheels.

I'm not happy and won't accept this as a repair. I'm taking it back to the dealership today.
I don't want to, but if push comes to shove I'll look at using lemon laws and hopefully find some recourse there.

Turns out it was a wheel bearing, which means they destroyed it when removing the trans and didn't actually care when they took it for a test drive hoping we wouldn't notice. Pretty terrible of the tech that worked on it.

We'll see. Trans doesn't feel like it used to, but I can't say it's horrible either. I really just care about it lasting a long time.

That is just a lazy Tech thats for sure. hopefully things are smooth from now on. I would look into Hondacare If you plan on keeping for awhile.

2017 EX-L 6 speed. At 42 K miles I began experiencing fluctuating RPM when going up hills. I took it to the dealer thinking it had something to do with the fuel system, To my surprise, they claimed the engine was overdue for a transmission flush. I was skeptical however, it solved the problem. The maintenance minder is set for a transmission flush every 30 K miles. It seems like the Honda transmission fluid degrades causing this issue.

Well I changed my fluid 4x and it went away also until it came back. I didnt care because my soon to be ex wife took it lol

There is a tsb for a sensor I believe it is and they also change the fluid, I would check if yours is covered under that tsb and perhaps get some money back.

Under normal operating I would change the fluid every 30k

you need to get the transmission reprogrammed (there's a TSB out there on this) as well. Exact same thing happened to my '17 EX, dealer did a 3x flush and reprogram under warranty, problem went away. Just installed a transmission cooler as well, which should help.

I recommend doing drain and fills with Valvoline Max Life ATF.

Common topic around here.

* Edit, oh wait, if it's a 9 spd. not sure if people are using it for that one LOL

Im sure these cases are 6-speeds.
I'm still waiting for someone's experience of using Valvoline MaxLife ATF in their 9-speed.

I had the fluctuating rpm gauge of death and black DW-1 ATF.
Multiple ATF changes using Valvoline MaxLife reduced the transmission flares to slightly noticeable. It wasn't until I disabled the VCM it stopped completely. Currently testing Amalie Universal Synthetic. It's performing well after 2 drain and fills. I also removed the OEM transmission filter and installed a Wix/Filtran 58953. It has done a very good job capturing the fine black clutch particles that were suspended in the ATF.

Did I mention to disable the VCM?
I use S-VCM.
