Does Toyota Sienna need transmission fluid change?

Toyota Sienna Transmission Fluid Change
The Toyota Sienna does require transmission fluid changes at regular intervals to help extend its service life. The transmission fluid and filter changes are typically completed as scheduled maintenance, and it’s important to ensure that the fluid meets the manufacturer’s specifications [[4]]. The dealership recommends changing the transmission fluid every 30,000 miles for optimal performance. However, the Sienna owner’s manual states that under normal driving conditions, it may not be necessary to replace the automatic transmission fluid at all, but it’s essential to consider what constitutes “normal driving conditions”.
If you’re unsure about when to change your transmission fluid, it’s advisable to consult a trained technician or refer to the maintenance guide for specific intervals. It’s also worth noting that if you have a transmission dipstick, changing the transmission oil can be a relatively straightforward DIY job, involving draining the ATF, refilling it with WS ATF bought from a Toyota dealer, and potentially changing the crush washer on the drain plug.
In summary, while the owner’s manual suggests that under normal driving conditions, it may not be necessary to replace the automatic transmission fluid, it’s important to consider the specific driving conditions and the manufacturer’s recommendations for optimal maintenance.
