Review on 🔧 AOIT 10 Pcs Aluminum Transmission Fluid Drain Plug Crush Washer Seal for Toyota Prius Corolla Tacoma Camry 90430-18008 - Ideal for Easy Transmission Fluid Changes! by Andre Noel

I use them in place of the 90471-PX4-000 Honda automatic transmission drain plug washers. Almost all Honda automatic transmissions use a drain plug with an inner diameter of 18 mm. However, on some Honda transmissions, the drain plug is recessed into a recess in the oil pan. If the outer diameter of the washer is too large, it will interfere with the pan. The outer diameter of this washer is 24mm which is perfect. I really liked that the seller posted pictures showing the outside diameter and thickness.
