2019 - 2021 Transmission Service Questions

When doing a standard Drain/Fill on the 2019+ transmission there will be three plugs. 1. Drain Plug on pan. 2. Level check plug also on pan. 3. Fill plug on side on transmission.

Does anyone know the parts numbers for the three gaskets that will be needed on each of these plugs? It seems some of the plugs have changed over the years and I can only find older part numbers.

I realize many reuse the gaskets but I just don't like to not be ready if something occurs.
Thanks

 

They're a crush washer, aluminum if I remember right, not much can happen to them. Losing one is about the only thing. Replacing is best of course, but I've never had an issue with them leaking when reusing in numerous applications through the years.

 

I think the drain is 90430-A0003 but not positive. I have been looking for all 3 for a while but not much luck. 80,000 miles and check plug just barely leaks so would like to replace all 3 seals next time I drain and fill.

 

Why not just go to the Toyota dealer and buy the parts there? I would hope they would be able to supply you with the correct parts.

 

It’s not worth the hour drive and the higher price.

 

Roman has been very helpful in helping me in the past to find OEM toyota parts. For whatever reason there online microfiche/parts list are terrible.
