Crush Washer size for fill plug of transmission

Can anyone help me? I’m tired of paying $10 shipping for a couple of washers from a dealer.
Many thanks. Our manuals only give the part number.

It’s a 10mm plug. Go to a hose shop nd ask for a 10mm Dowty washer or seal.

Pete, you’re always a saint. I don’t think there is such a thing as a hose shop in my part of the world.
Here where I live, I need a Mx by .something so I can order one Amazon.
Bless you just the same.

10mm Dowty Washers: Linky

For odds and ends, like Dowty Washers, I usually try MG Cycle or Bell Metric.

Then the usual suppliers AF1, McMaster-Carr etc, etc.

Best of luck with your GRiSO.

Thanks to all but I’m looking for the big washer size that is on the fill plug of the transmission. No worries, I’ll spend the $20 to have a couple sent to me from AF1.

Ahh, John, sorry. Got off on the wrong tangent.

If you're able to measure it then Bell Metric has various sizes of the Dowty Washers, Copper or Aluminum Crush Washers available.

Back on track . . .

Per the Factory Parts Manual: Fill plug crush washer p/n GU18144350, 18,25x24x1.

You're going to pay a flat rate shipping charge so, to me, it makes sense to add additional part numbers for future use.

Although the Bell Metric supplied copper crush washer is an extra 0.5mm thicker, it's listed at $0.51 each.
You could pretty much get a lifetime supply for your twenty bucks. They will ship you one or two if that's what you want.

Thank you Ratso. And, I used to be a neighbor of yours when I lived in Zionsville until 2008. Spent 22 years in Indiana.
Thanks again.
