Honda 90471-PX4-000 Genuine Automatic Transmission Drain Plug Washers — 18mm (Bag of 5)

A leaking transmission drain plug, fluid stains under the vehicle, or a low transmission fluid level warning — these are common signs that your drain plug washer needs replacement. The crush washer is a single‑use sealing gasket that compresses to form a leak‑tight seal between the drain plug and the transmission pan. Reusing an old washer can cause fluid leaks, which may lead to low fluid levels and potential transmission damage. Replacing it with this genuine Honda washer ensures a proper seal and protects your transmission.

This is a factory‑original Honda transmission drain plug washer (OE part number 90471-PX4-000) with an 18mm inner diameter, specifically designed for automatic transmission drain plugs on Honda and Acura models. It is made from high‑quality copper material that compresses evenly under torque to create a reliable, long‑lasting seal. This listing includes a bag of 5 washers, offering a convenient supply for multiple transmission fluid changes. This is the same washer sold at Honda dealerships.

FAQ

FAQ

Is this a genuine Honda part or a copy?
This is 100% genuine Honda OEM — in original factory packaging with Honda part number printed on the label. It is not an aftermarket brand or a replica.

Will these washers fit my 2010 Honda Accord?
Yes — the 2010 Accord with the automatic transmission uses this 18mm washer for the transmission drain plug. We recommend verifying with your VIN.

Can I reuse the old washer?
No — this is a crush washer designed for one‑time use only. Reusing an old washer will cause leaks. Always use a new washer when you remove the drain plug.

How many washers are in the bag?
This listing includes a bag of 5 washers.

What is the torque spec for the transmission drain plug?
The typical torque spec for the transmission drain plug is 30–40 Nm. Always refer to your vehicle's service manual for the exact specification.

Are these the same as the engine oil drain plug washers?
No — engine oil drain plug washers are typically 14mm (94109-14000). This washer is 18mm and is specifically for transmission applications.

Can I use this washer for differential drain plugs?
Yes — this washer is also used on some Honda differential drain plugs. Please verify the size and application on your vehicle.

What is the correct installation procedure?
Place the new washer onto the drain plug, then thread the plug into the transmission pan. Tighten to the specified torque from your service manual. The washer will compress and form a seal as the plug is tightened.

Will these washers fit my Acura TSX?
Yes — the Acura TSX uses the same 18mm washer for the automatic transmission drain plug. Please verify with your VIN.

Can I use these washers for other 18mm plugs?
Yes — these washers can be used on any 18mm drain plug that requires a copper crush washer, provided the plug and pan are designed for this washer.
