Toyota Repair: 2004 toyota sienna transmision fluid change, toyota sienna, toyota dealer

Question
I plan on changing fluid myself but not sure how to drain fluid without dropping pan

Answer
This year Sienna uses WS (world standard) transmission fluid, the recommended fluid replacement is 100,000 miles, the transmission is sealed and there is no dipstick,servicing should only be done at the toyota dealer because special service tools are required.
