Toyota Sienna Transmission Fluid
The correct transmission fluid for the Toyota Sienna, how much it takes, how often to change it, and how to check the level.
Quick answer
The Toyota Sienna typically uses Toyota Genuine ATF WS. Refill capacity on a drain-and-fill is ≈ 3.5–4.0 qt drain-and-fill, with a common change interval of 60,000–100,000 mi; sooner under severe service. Dipstick: No. The 2021+ Sienna is hybrid-only with an eCVT and different fluid — this covers 2004–2020 automatics.
