    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:

    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!
