Just got a 2019 pilot lx awd. Did some searches and didn't find much. Can anyone tell me the average MM milestones for fluid changes (ATF, transfer case, rear diff)? I found the post that talks about washer sizes, thanks!!!

Just working from memory based on general experiences reported on this forum....

ATF and transfer: Every 45K or so
VTM4: first one at 20K, then every 35K or so

At 13k, have B16 already. Owners manual says DPSF-II 1.92 qt for rear diff, same as my CRV. Transfer assembly calls for Honda Hypoid Gear Oil HGO-1 0.45 qt. Doesn't look like VTM4 to me. Nowhere in the owners manual is VTM4 mentioned.

Rear differential is part of the 'i-VTM4' (Intelligent VTM4) system.
Transfer and transmission fluid changes aren't required until a '3' code appears.

VTM-4 Honda fluid was used in previous models of the Pilot and other Honda vehicles for the rear differential. The 3rd generation Pilots (2016-2020) now require the DPSF-II fluid instead and it is even stamped on the rear differential now.

My B-6 rear differential fluid change code popped up around 10500 miles or so. It doesn't need to be changed until the next oil change which on my car should be around 16000-18000 miles. I am at 12000 miles now with 70% oil life.

The code comes up early just to alert you as to what services will be needed at the next oil change, not what has to be done immediately.

27000 miles and had code 3 for transmission fluid. Did that and the transfer case. Transmission fluid did not look great, lots of metal on the drain plug, took an entire shop rag to clean it off. Transfer case oil did not need to be changed. It looked brand new. Will do that in two code 3's from now.

Don't be afraid to do transmission fluid on shorter intervals without resetting the MM for it. The VCM system really aggregates the transmission fluid in these cars, especially if you do a lot of highway cruising. Recommend you 1. disable VCM (with VCM Tuner II or SVCM), 2. change transmission fluids more frequently or switch to a full synthetic like Amsoil, Amalie, or VML that can handle the extra heat, and 3. consider installing an ATF cooler.

I am using standard DW-1. I had had the ATF cooler since day 1. Changing more often than 27,000 is a bit nuts, this is a family car not an exotic sports car.

What can I say, it's a Honda! Tell that to the Gen 2 Odyssey owners that changed their fluid every oil change.

If you have the cooler I'm surprised the fluid was in such bad shape. Do you tow or do a lot of heavy load hauling? Was it just the plug, or did the fluid itself smell burned up too?

Fluid was a little dark, I think the metal was just on the plug. Normal driving, no load.

Yeah, you're probably OK then. DW-1 does have a reputation for turning dark. My above comments stand though, especially about disabling VCM.

Even if you changed your fluid every oil change, your going to have metal on the magnetic drain plug. Unless it chunks, then it's normal.
