Should I service my transmission on my '07 Yaris? - Toyota Yaris Forums

Drop the pan and change the filter. You don't want to use a worn out filter. And then drain and fill it another one or two times for good measure since the old fluid is burnt up.

You may find the transmission dies sooner instead of later if it's been abused. That's due to not changing the fluid for so long, not because you decided to do it now. You can use some of the additives to make it thicker to limp it along the same way your current fluid (may) be doing now.

As for dealership only fluids, they don't exist on American cars due to the Magnusson-Moss warranty act. Any dealership only fluids are lifetime free changes. Unsurprisingly, when a car company that sells in the US decides to use a special fluid, they sell the rights to use it to anyone willing to pay. Just look for the fluid that matches your car, the brand is not important.
