Thank you for allowing me to help you with this concern. Your 2000 Toyota Sienna transmission uses Dexron II or Dexron III transmission fluid which is not compatible with Type T-IV fluid. Here is a bulletin showing that your Sienna uses Dexron fluid.

And here is the Toyota bulletin showing the these two fluids are not to be mixed.
