I don't think you should be in any big hurry to get this done. Wait till Honda straightens out their problem.

 

Makes sense and agreed - at least its documented. Thx!

 

On my UK spec CR-V hybrid, this is listed as a service item at 12500 miles and then every 50000 miles after that. But (for some reason that I don't understand) it's not included in the 5-year service package that came with the car. So I did my own rear diff fluid change - it's an easy job, and I think it's important to keep the diff plates and dual pump system clean.

 

Yeah looks like we have different plans in the USA as I purchased the separate VSC with Honda for up to 60,000 miles and that item is included. As I am paying for it with the plan I purchased, I expect them to resolve this on their behalf or refund me for the plan if they changed the terms and conditions after I signed up but looks like I might be the first on this forum to experience this so so will stand by as more others come across this (or not! Lol)

 

Not sure why they would have a problem changing the rear diff fluid, it's basically as easy as an oil change.

 

Read the thread. Problem is getting it serviced for free under the plan. The threadstarter shouldn't have to pay for it. Honda needs to fix the glitch in the system.

I would get it changed. Find another dealer if yours can't take care of it now.

 

$200 dollars for an oil change??
I bought the rear diff fluid from a Honda dealer and changed it myself.
I think at the time it was less than $40 for two bottles.
When doing it, make sure the fill plug can come out first.
Do not want to drain the fluid only to find you can not fill it.

Or wait until Honda fixes their issues.
/\ Good luck

 

I’ve got just under 8k miles on a 2023 purchased in December and I’m already getting sub maintenance code 6 (rear diff fluid change). I wasn’t planning on changing it this early so I’m hoping it’s covered under the 2yr maintenance plan. I drive on mainly flat roads and drive in normal mode 99% of the time so is this normal?

Edit: Above is what I just posted about this before realizing someone has already experienced this, moderator merged with this thread which makes sense. Anyways, I’ve got 8k miles on my EX and I’m getting maintenance code 6 already. About to make an appointment with my dealer, will update you on what they say.

 

Any updates? Does the dealer charge for Rear differential fluid or is it included in the free service??

 

Regardless of what the last poster says, the rear differential fluid change is included with all 2023 CR-Vs for 2 years. If your dealership is refusing to do it under the maintenance plan, report them to Honda corp or take it to another dealer

 

So the service pass is useless to me then since my dealership already gives free lifetime oil changes and costco offers free lifetime tire rotations? 🙃

 

Here's the link to the Honda website about Service Pass. It's definitely not officially covered but I imagine some dealers may take it upon themselves to do it as goodwill.

https://automobiles.honda.com/news-and-events/honda-service-pass

 

That page isn’t very helpful as it doesn’t note everything included. It just lists three items included but doesn’t delineate what else is included, if anything.

Does anyone have a link to the full terms & conditions?

 

Is servicing the automatic transmission different for the Gen 6? I don't find anything on transmission service for my 2023 CR-V on YouTube, only previous models. Thanks!

 

If you don't have a hybrid than it's the exact same transmission as the 5th gen and serviced the same.

Thanks!!!

Any updates here? I've got an A16 service scheduled for later this week and would like to know what to expect.

 

My vehicle recently produced maintenance minder "A16" code, which is oil+filter (A), tire rotation (1) and AWD fluid (6). Service was scheduled. The dealership said that the AWD fluid was not covered under the free service plan so that service was not performed (I will take care of that).

My question is: should there still be a service code for "6" since the "A1" part was completed (sort of, that's a different story) but the AWD fluid service was not done? I see in the maintenance menu that each service section can be reset independently or there's another option to reset "all service due". Ultimately, I want to understand if the AWD fluid service was reset when it shouldn't have.

Thanks!

Yeah the dealership definitely reset all items when they should’ve only reset the A1. Same thing happened with me so I reset odometer ‘A’ so I could keep track of how long past the oil change before I finally changed it, which ended up being around 1k miles after the trip to the dealer. I didn’t have to reset anything since the maintenance item 6 had prematurely been cleared.

 

Vehicle was in today for the A16 service. Had to pay for the rear differential fluid change, as it's not part of the 2-year annual maintenance plan. Wasn't a big surprise, after following this thread for a while. Oh well.

 

As noted here:

What the clutch pack fluid replacement(hybrid only) also known as the (e-cvt) Someone mentioned over at the accord forums it was a 30k change with 2.5 quarts of whatever fluid. I assume gear oil?

 

I'm pretty sure it's ATF

 

Correct, its about 11 $ a quart. I assume it's not to hard to change. If the dealer does it will be around 200$ maybe

 

I might assume it would be easy. There actually could be some small steps Honda wants you to do, like make sure it's at some temperature, or drive it to actuate the dog-tooth clutches first, etc., I don't know.

I've done this in the last few years on 3 hybrids and EVs, and they all had upper fill (level) plugs. One hybrid was actually under-filled a bit at the factory, so maybe there is a reason to get it done early just in case.

I want to do mine early to try to get out any metal break-in dust, maybe install a new magnetic drain plug, and get out any RTV factory sealant that gets loose in engines/trannies during factory assembly.


Anybody gained access to the service manual dealership PDF files at Service Express on this Gen 6 Hybrid transmission (and rear AWD diff while you're at it) and be willing to put out a step by step guide for us folks who want to change those fluids ourselves on 2023-2024 CR-V Hybrids? techinfo.honda.com

I tried and failed to rent access for a day to Service Express for $30. I tried that a couple of weeks ago.
Details:
It kept erroring instead of giving me access to dealership-level "Service Information System" shop service manual pdf files, and it may have had something to do with the fact I'm using Windows 11. The customer service guy on the phone had no idea what the technical problem was and just refunded my credit card. There was another warning page I saw that said their servers were having trouble that day, maybe that was the problem, so I'll try again soon to see if it works, as you can always get a credit card refund anyway.

There are a couple of youtube videos, on earlier (1-clutch) CR-V Hybrid transmission fluid drain service, and they are partially helpful. I'd like to have bolt torque tightening specs and any other info that could make this "tricky", i.e., maybe it needs to be at a certain temperature, how to make sure it's filled to the right level, etc. .... There may not be much extra steps to do, although another brand of Hybrid I did recently had a couple of slightly tricky "inside info" steps.

Summary of some info found so far:
On one youtube video on a 2021 CR-V Hybrid transmission fluid change, he just pointed out the upper accessible (under the hood) plastic pull plug to put fluid into, while another youtube video had the service guy use what looked like a Level-Fill Plug from underneath. Both the earlier version of our Hybrid. And both not entirely clear or complete. I'll look around to try and find a current-model Accord Hybrid youtube transmission fluid change, and a search so far turned up nothing, I'll try again.

 

I got the Service Manual (rented downloads for a day) and did the Transmission and AWD Rear Diff fluid changes.
My 2024 Hybrid only has about 3,000 miles on it, so this is to get out the break-in metal dust.
Then I guess go about 40,000 miles or so for transmission fluid changes, and 20,000 miles for AWD Rear Diff fluid changes, something like that.

Transmission:
Fluid: HEVF Type 1.0 (for 2023 and newer hybrids only, earlier Hybrids used DW-1 ATF fluid)
Capacity: Takes about 3.1 quarts fluid after a drain. Save a little of the old fluid so you only have to buy 3 quarts of this expensive fluid, and use old fluid for the small top-off level when the transmission is warm.
Torque Specs: 32 lb-ft for the Fill Plug, and 36 lb-ft Drain Plug
Check the level on the fill plug when the transmission is warm, not too hot, maybe about 20-50 degrees above room temperature, after driving it a mile or two. In fact, they want you to check the Level Plug fluid level withn 1.5 minutes of parking the vehicle (I drove mine up on 4 2x4 pieces of wood to raise the car just slightly to allow me enough room to crawl under there and quickly get to the Level Plug within the crazy 1.5 minute schedule, weird, but that is the Service Manual.)
More precisely, the Service Manual says to drive it a short bit, maybe a mile or two, over 12 mph, and then Check the Level (warm) again, top it off, and tighten everything down.

Change the crush washers. 18 mm and a 20 mm one.

Always loosen or remove the Level Plug or the fill plug that is under the hood on top (the L-Handle pull plug immortalized on youtube & this forum), just to be sure you can get new fluid in before you drain fluid out.

Other notes:

If you search on youtube for Honda Hybrid Transmission Fluid , you'll see they usually say to look for the fill-plug top-side when you open the hood, the pull-plug (not screwed-in) with the L-shaped tiny handle sticking out. It is on your right side when standing in front of the hood looking into the engine bay.
That L-Handle topside plug did come in handy for me, since it was much easier to pour the HEVF Type 1.0 fluid into there using a tube attached to the HEVF Type 1.0 fluid bottle, while I still used the Level Plug (bottom-side) to make sure I did not under or over-fill it.

Make sure you turn the vehicle off when changing the fluid or when checking it. It's a hybrid so you might forget, but it does hum a little even when the ICE is not running.

Make sure the vehicle is level when filling or checking the fluid. I put mine up on 2x4 pieces of wood, all 4 tires, centered on each piece of wood, just drove it on there, level, easy. Jack stands are good, just make sure you know how to safely and redundantly (backup supports) support the car level if you do that. Safety.

Many backyard mechanics doing this on youtube just drain it and then re-fill it with whatever the Owner's Manual says is needed. They don't check the Level ! This kinda works OK, I'll say, since mine took 3.1 quarts (supposed to take 3.0 qts), not too far off from what the Owner's Manual said. ( From a dry new transmission, you actually need 5.4 qts, so you see that a lot is trapped up in there.) Only buy 3 new quarts, and save a little of the old fluid in a clean container for what top-off you might need.

The Transmission Drain Plug is not magnetic, though the AWD Rear Differential drain plug is. The transmission probably does have an internal magnet inside, although you can never clean it.
I replaced the original plug with a neodymium magnet plug, M18x1.5 size ( https://www.amazon.com/gp/product/B0BB5YVHK3/ )

Ford Hybrids (C-Max & Maverick) I've done in the past also require the Level Plug to be checked when the vehicle is slightly warm, and after you drive it just a bit, I think to get any possible air pockets out, with a final Level Check done to make sure you got it. ... Honda is similar here. Technically, the level is only "perfect" if the transmission is warm, not max-hot, checked at the Fill Plug for drips, although DIY backyard mechanics on youtube never seem to mention that.

Now for the AWD Rear Differential fluid change.
It is the same for the earlier CR-V's: https://www.crvownersclub.com/threads/replacing-rear-differential-fluid-on-hybrid-cr-v.226974/
Still holds for the Gen 6 (2023 and newer Hybrid CR-V's).
I didn't use jack stands (car must be level of course). I drove up on 4 pieces of 2x4's laid flat, like I did changing tranny fluid too, to give me a bit more vertical room to work. My torque wrench is not too long, so this worked. Cramped in there. Still easy. Pump or squirt the new fluid into the Level Plug using an attachment on your plastic fluid bottle, like this one: https://www.autozone.com/shop-and-g...garage-tools/oil-spout/p/flotool-transmission-fluid-and-gear-oil-spout/2366_0_0 probably on Amazon, maybe Walmart has it, common thing, or a hand pump that fits on your bottle works well too.

Unlike the transmission fluid change, you do NOT have to warm up the rear diff before checking the Level Plug dripping. Nice. ((( I did this in a 2009 toyota Venza AWD a couple of years ago, and they want you to drive it around a bit after you change the fluid, and then check the level warmed up some. Not on our Honda's though. )))
Always loosen or remove the Level Plug, just to be sure you can get new fluid in before you drain fluid out.

There is one strange Service Manual step though, "After Replacement" of the fluid in the rear diff (I didn't bother with this, I just want clean fluid back there!):

I might try that at some time in the future. The AWD system should throw diagnostic warnings/codes when it doesn't work right as you drive anyway, you'd think. Why is this necessary?

 

Not sure if it makes any difference. The service manual says to enter maintenance mode when replacing transmission or differential fluid. Mechatronic missed mentioning this procedure from the service manual. Honda probably making it sound more complicated than necessary.

Thank you for sharing that detailed information.

 

Would you change the cvt trans oil early on the 1.5? I'm doing the rear diff. Car is over a year old with 7k on it.

 

Doesn't make any sense yet. You should follow the MM.

BUT. The transmission is the only thing you can change fluid in earlier than MM. 30K is a good number if it hasn't alerted you earlier.

 

I agree, 30K is a safe standard for CVT's, regardless of the MM

 

The dealer did the rear differential at 25k (km) and I just had a local mechanic do the transmission fluid at 85k (km) for the first time and the rear differntial again on a 2017 touring. Both fluids were still ok.

 

I have just under 9000 miles. The 6 came on. It cost me $157. Wasn't covered, according to the Dealer

 

Yep, my dealer told me the same thing and charged me. I just changed mine today at a bit over 30K miles, and it took a breaker bar to get the fill plug loose. I have serious doubts that the dealer touched this, at the 15K mile service.

 

my 2024 Touring had MM A16 at 10,020 miles. Thought it was a little early for the rear diff oil change, but I'm on extended vacation and expect I'll have more than 4K miles of fun before I get back home, so I paid the dealer to do the rear diff oil while I got the covered (free) oil change. They did not rotate my tires, claiming the tires didn't need it at this point.
Rear diff oil charge was $196. I know it is ridiculous, but I don't have access to tools or lifts so I bit the bullet.

 

The maintenance schedules honda incorporates is only a money grabbing scheme in my opinion. None of the scheduled maintenance periods make any sense. Rear diff oil change is normally performed between 30-60k miles. The dealer told me my wife's 2013 crv trans fluid change interval is 30, again 50 to 100k is the norm depending on driving conditions.
I've done all my own fluid changes for over 50 years, it's getting harder and harder to find non biased maintenance information these days on new cars.
My 2024 sport touring hybrid has only about 40 miles on it; the Search begins now for all necessary tidbits I'll need to perform my own maintenance on this rascal.
Maybe someone has written a book, gen 6 CR-V maintenance for Dummies.

Don't ever go by what the dealer says. You can't go wrong following the owners manual.
