Tranny drain and fill crush washers

About to do a drain and fill, and level check on my 06 DC. For the drain, fill, and fluid level check bolts, are there crush washers I should replace?

Watched a few YT videos but no mention of them


Thx

 

I haven's ever replaced them on any of my vehicles.

 

Strangely not the case for the earlier year Tundras. All they seem to give out are crush washer replacements even though my original gasket was not.

 

I helped my 3rd gen friend do a 50k service, his transfer case has pipe thread plugs with 3/8 drive holes, so much easier and less hassle, that’s the only thing I’ll give kudos to

 

I have an 06 DC.

The fill plug has a rubber o-ring on it. I don't replace it.

I believe my drain and check had flat copper gaskets from the factory. The parts list shows crush washers

35178-30010 as the replacements.

 

Sounds typical. You could probably keep reusing the flat washers. First time a tech does it though, consider it gone. They did to mine.

 

My problem is remembering which way they're supposed to go. They aren't the same on both sides. I don't think it really matters, but there is a correct way.

Whatever research I did on the tranny drain & fill must have recommended the crush washers, because I have a few of them now. The washer that came off looked like a crush washer too. I know the previous owner did a tranny flush.
