    I just finished up changing the fluid in the transmission on my 2013. I noticed that when I left the truck sitting overnight to let it cool below the check temperature, the gasket for the overflow/check plug is leaking. Upon closer inspection, it looks like they slapped two gaskets on top of each other during assembly. Worked out so far, but now it is seeping.

    I haven't had much luck finding part numbers on the OEM online places (I guess they really don't want you servicing these things themselves. So, I did a generic search and found this link:
    $10 Rexka 20pcs Transmission Drain Plug Gasket Compatible with Toyota Lexus Truck 35178-30010 4Runner, Celica, Land Cruiser, RAV4, Sequoia, Tacoma, Tundra,GX460, is F, IS250, IS300, IS350, SC300, SC400
    https://www.amazon.com/Rexka-Transmission-Gasket-4Runner-35178-30010/dp/B07B7HKD54

    Looks like it is the right size according to my measurements, and it appears that Tundra is on the list for what it fits. Was wondering if @Roman could help out and confirm?

    Just did a drain/fill on my tranny. I went to my dealer and told them what I was looking for and they got me the gaskets and o ring. Sorry I don’t have the part numbers but I bet a call/visit to your dealership parts dept would get it figured out.

    It just depends on which plug you're needing it for. Check out the parts diagram here:

    It would be 35106B in that diagram. I just did a search on toyotapartsdeal.com for that part code, and it came up with the one I ordered this weekend. So I think that I am ok. However, there are a couple of other sites that say it won't fit. But, the dimensions listed match what I measured. So, hopefully it will work.

    Thanks!

    Transmission will require two washers and one O-ring. These numbers are good for every Tundra ever made along with the vast majority of all Toyota/Lexus vehicles since mid 90's.
    $10 35178-30010 luxlead 20 PCS Transmission Drain Plug Gaskets Oil Crush Washer Seal Rings Compatible with Toyota Lexus 4Runner Sequoia Tacoma Tundra Lexus GS450H, IS250/350, LS430, LS460, Replaces 35178-30010
    35178-30010 - you will need two of these. One for drain plug and one for fluid leveling or overflow plug.
    90301-15004 - one of these for the 24mm fill plug. This one most likely won't need changing but there cheap.

    Only issue is the two crush washers(35178-30010) are normally available at ever dealer in N. America but the single O-ring is almost never in stock at dealerships and need to be ordered online.
