We now know the minimum for transmission fluid life.

Thanks to Tim K we now know that the minimum life expectancy of transmission fluid in a sealed system is 10 years or 100,000 miles. Otherwise the warranty wouldn't cover the transmission.

His comments also leads me to think it's slightly over 12 years, but that is conjecture on my part.

I suppose that's one way of looking at it. Personally, I'm done with the transmission fluid discussion. People have their viewpoints and there is really no sense arguing with them. Change it, don't change it. Whatever floats your boat.

So, it was 70K miles before?....huh. Greatly improved I see.
 
Funny story, I changed the transmission fluid in my 2009 Tacoma at about 15k miles because I drained that instead of the oil. I quickly learned how to pump tranny fluid into a sealed transmission. I can admit that lol. I bought the Tacoma with 11 or 12k miles on it and had decided I was going to teach myself how to change oil as I wanted to do it at home. Nobody had ever taught me. The Tacoma has a transmission drain plug that looks exactly like an oil drain plug and it's about where you would expect it to be for oil. Except it came out red. That created a long night and a little bit of panic.

That mistake helped me discover the TacomaWorld forums where I was quickly helped and they let me know if happened all the time in those trucks. Been a member ever since lol.

Edit: My dad refused to let us change the oil growing up because "It made a mess and it's so cheap to have a jiffy lube place do it" I think they were typically $19.99 to $24.99. Very different from the $100+ oil change now.
