Great Value, Perfect Fit – Just Like OEM
I bought this 15-pack of AUTOMAJOR transmission fluid drain plug crush washers as a more affordable alternative to the OEM Honda part, and I’m really impressed with the quality and fit. I’ve personally used these on both a 2018 Honda Civic 2.0L CVT and a 2019 Honda Accord 1.5 Turbo CVT, and they fit perfectly on both vehicles’ transmission drain plugs. No leaks, no issues. The seal was tight and consistent, just like with the original factory washers. To be honest, I can’t tell the difference between these and the OEM ones from Honda. The material and dimensions seem spot-on, and installation was smooth. For the price, it’s a no-brainer—15 washers for about the cost of 2 or 3 OEM ones at the dealership. If you do your own transmission or differential fluid changes on a Honda or Acura, this is a great item to keep on hand. Excellent value and performance. I’ll definitely be buying these again.

Great OEM replacement washer
Not much to say. They work perfectly on the Honda 6 speed transmission in my wife’s’s Honda Pilot. Honda redo ends changing these after every use, so getting them in bulk makes sure you always have one available. They are the right size and appear to crush like they are supposed to. I’ve used two of the, with no issues. I have plenty of spares to use. Oh, and these are much cheaper than you can get them at the dealership.

Good value
Does fit well and seal up as expected and the value of this pack means that a replacement on every change is not a big deal. I was expecting a bit flatter of a washer surface, but maybe that was just me seeing things wrong on the pictures given. It is a nice quality oring with just enough five to compress but not enough to weaken and tear.

Great Crush Washers
Used on a Honda. These crush washers seal correctly and fit the factory drain bolt without any issues. The price is excellent for single-use parts you should replace at every oil change.
