Product Details

✓Where this washer sits depends on the drivetrain, and that is the part nobody explains. On front wheel drive Honda and Acura it seals the transmission drain plug — on a 2022 Civic with the CVT it appears in the AT transmission case group of the parts diagram. On all wheel drive it moves to the rear differential: on a 2022 Pilot AWD the same number sits in the rear differential group. One washer, two places, depending on the car.

✓Fifteen washers in aluminum, 20 mm inner by 27 mm outer by 2 mm thick, which is 0.79 in by 1.06 in by 0.08 in. Replaces Honda and Acura 94109-20000, written on parts screens as 9410920000, and the number it supersedes, 90413-551-000. Crosses to 095-025 and 097-851CD. Soft aluminum flows into the machining marks on the case as the plug comes down to torque and then holds the clamp load.

✓Two other sizes exist on the same cars and they are not interchangeable. Some transmission drain plugs take the 18 mm washer, Honda 90471-PX4-000. The engine oil drain plug takes the 14 mm washer, Honda 94109-14000, on every Honda and Acura here — that one is never this size. Both are separate AUTOMAJOR listings, and a twelve piece combination pack carries the 20 mm and 18 mm sizes together.

✓Fits Honda Accord, Civic, CR-V, Odyssey, Pilot, Ridgeline, HR-V, Passport, Insight, Element, Fit, S2000, Prelude, Crosstour, CR-Z, Clarity, Del Sol and CRX, and the Acura range alongside them. Coverage is wide because the washer serves the transmission on front drive cars and the rear axle on all wheel drive ones. Match the number on the old washer rather than the badge on the car.

✓Crush washers are single use. Honda calls for a fresh one at every fluid change, and a reused washer is one of the more common reasons a case weeps a week after a service: once flattened it sits lower the second time and no longer fills the same marks. Suited to ATF DW-1, CVT fluid HCF-2, manual gear oil, Dual Pump Fluid II and differential fluid. Torque to the figure in your service manual.
