Definitions: Honda owner's manuals, Maintenance Minder section (2016 and 2024 Civic, 2013 and 2018 Accord, 2017 CR-V, 2018 Odyssey, 2016 and 2021 Pilot). Manuals: 2024 Civic Hatchback Type R Owner's Manual, 2021 Pilot Owner's Manual. Your own manual decides which items apply to your engine and drivetrain.
B13 means three jobs are due: B (replace the engine oil and oil filter, plus Honda's full inspection of brakes, steering, suspension, driveshaft boots, brake lines, fluid levels, exhaust and fuel lines), 1 (rotate the tires) and 3 (replace the transmission fluid). There are no air or cabin filters in it - those are the 2, and with them the code would read B123.
The 3 runs on its own clock, separate from the oil life. Honda prints no fixed normal-driving mileage for it - the Minder decides - and only some manuals add a severe-duty figure (every 25,000 miles for the CVT in a Civic, Accord or CR-V driven in the mountains or at low speeds; none at all for the Pilot). B13 is what you see when that clock runs out on a B visit; on an oil-only visit the same job shows as A13.
What the 3 means in practice depends on the transmission: Honda HCF-2 in a CVT, a specific Honda ATF in a conventional automatic, and on an all-wheel-drive Pilot the transfer fluid as well. The table below lists what Honda specifies for each model and year.
B13 puts the transmission fluid next to an inspection of the driveshaft boots and the fluid levels, which is the right pairing. While the fluid is out, look for leaks around the transmission pan and the axle seals, and for torn driveshaft boots flinging grease.
A fluid change that comes back with a leak finding is a result, not an upsell: ask for the finding in writing.
The correct fluid depends on your transmission, not the badge: HCF-2 for CVTs, DW-1 or another Honda ATF for conventional automatics, with separate fluids for hybrids and manual gearboxes. The table below lists models and years. A Pilot with all-wheel drive also lists transfer fluid under the 3; a CR-V manual does not.
On a CR-V with AWD the rear differential is a separate item, the 6, and B13 does not cover it.
Ask for three things on the quote: the exact fluid name (HCF-2, DW-1 or the ATF type from the table below), the method, and the date and mileage you will be told to write down. A drain and refill replaces only part of the fluid, so the method is worth knowing.
Keep the invoice. The next B13 is easier to judge when you can see when the last transmission fluid change happened.
| Item | DIY | Shop |
|---|---|---|
| Oil and filter (0W-20) | $40-$60 | $70-$130 |
| Tire rotation | Free with a jack | $20-$50 (often bundled) |
| Transmission fluid (drain and refill) | $50-$90 | $150-$250 |
| Inspection | Your own eyes and a checklist | Usually included in the B service |
| Typical all-in at a shop | $85-$140 total parts | $240-$400 |
Ranges, not quotes - parts pricing and shop labor vary by region and model year.
The oil, filter and rotation portions of B13 are ordinary DIY work. The transmission fluid needs more care: use the exact fluid your model specifies (CVT fluid and conventional ATF are not interchangeable, and the wrong one can damage a CVT) and the correct fill procedure, which on many Hondas means checking the level through a plug at a specific fluid temperature rather than with a dipstick.
A reasonable split: handle the oil, filter and rotation yourself, and either learn the transmission fluid procedure exactly or pay a shop for that one line item. The inspection is the other piece worth having done by a shop periodically, since a driveway check cannot fully replace a lift.
Honda prints no fixed mileage for sub-item 3 under normal driving on any of these models - the Maintenance Minder decides. The severe-duty column is the only mileage Honda gives, and only where the manual prints one. HCF-2 is CVT-only; it is not interchangeable with Honda ATF, and Honda's ATF types are not interchangeable with each other.

Transfer fluid: the Pilot's owner's manuals list it under the 3 on all-wheel-drive (i-VTM4) models. The CR-V manuals list no transfer fluid item at all - on an AWD CR-V the rear differential fluid is a separate item, 6.
Source: each model year's Honda owner's manual (Maintenance Minder and Specifications sections), as recorded and cited in this site's per-year maintenance schedules.
B = replace the engine oil and filter, plus a full mechanical inspection. 1 = rotate the tires. 3 = replace the transmission fluid (on an AWD Pilot, the transfer fluid too). No air or cabin filters - those belong to sub-code 2.
Typically $240-$400 at a shop, or roughly $85-$140 in parts if you do it yourself. The transmission fluid accounts for most of the cost beyond a standard B service.
No. A13 is oil, rotation, and transmission fluid, with no oil filter and no inspection. B13 adds the oil filter and full inspection on top of the same rotation and transmission fluid.
A B service, a tire rotation and a transmission fluid change. On a 2014-or-newer Civic with a CVT that fluid is Honda HCF-2, with a severe-duty figure of 25,000 miles for mountainous or low-speed driving; manual-transmission Civics use Honda MTF (37,500 miles severe-duty in the 2022-and-newer manuals).
The same B, 1 and 3 - and on an all-wheel-drive Pilot the 3 also means replacing the transfer fluid. Honda prints no mileage for the Pilot's 3, normal or severe. The fluid depends on the year: ATF DW-1 (6-speed) or ATF-Type 3.1 (9-speed) for 2016-2022, and ATF-TYPE 2.0 for the 2023-and-newer 10-speed.
No. B13 covers the B service, a rotation, and transmission fluid only. The engine and cabin air filters are sub-code 2 and would show up as B123 if they were also due.
The oil, filter and rotation are easy DIY jobs. The transmission fluid needs the correct fluid type and fill procedure for your exact model - if you are unsure which fluid your Honda takes, that piece alone is worth paying a shop for.
