Do Toyota Sienna have CVT transmission?
Yes—in the current Sienna lineup, Toyota uses an electronically controlled continuously variable transmission (eCVT) in the hybrid system; older gas-only Siennas used a conventional automatic.
Understanding the Sienna transmissions by generation
Below is a quick breakdown of the transmission setups for Sienna models across generations.
- 2011–2020 Sienna: 6-speed automatic transmission paired with a 3.5-liter V6 (gasoline models).
- 2021–present Sienna: Hybrid-only with a 2.5-liter engine paired to Toyota's Hybrid Synergy Drive, using an electronically controlled continuously variable transmission (eCVT).
In short, the Sienna moved from a traditional automatic in earlier years to an eCVT in the current hybrid generation.
What this means for driving
But the driving feel and maintenance needs differ between a conventional automatic and an eCVT. Here is a quick overview:
Driving characteristics
Conventional automatics provide defined gear changes and predictable torque delivery, while the eCVT offers smooth acceleration with a continuous range of ratios. In the Sienna’s hybrid setup, the engine and electric motors coordinate for efficient propulsion, especially in city driving.
Maintenance considerations
CVT (including eCVT) systems require specific transmission fluid and service intervals. Toyota typically recommends periodic CVT fluid changes and checks, so refer to the owner's manual for your model year and drivetrain.
Bottom line for shoppers
If you're shopping for a used Sienna, check the model year to determine transmission type. If you want the latest fuel efficiency and a hybrid powertrain, expect the eCVT hybrid; if you prefer a traditional gas model from earlier years, you'll encounter a conventional automatic.
Summary
The Toyota Sienna’s transmission technology has evolved with its powertrains. Early gas models used a conventional automatic (6-speed in 2011–2020), while the current hybrid-only generation (2021–present) uses an eCVT as part of Toyota’s Hybrid Synergy Drive. For buyers, the key is to verify the drivetrain if you’re seeking a particular transmission experience.
