Which Honda Odysseys have 10-speed transmission?
In brief: Honda Odysseys built from model year 2018 onward use a 10-speed automatic transmission; older Odysseys (pre-2018) use smaller, multi-speed automatics. This article explains which model years include the 10-speed unit and how to verify it when shopping.
Model-year coverage
Scope of availability
Below is the quick reference for when the Odyssey adopted the 10-speed automatic and whether it spans all trims.
- 2018 model year to present (all trims) use Honda's 10-speed automatic transmission (10AT).
In practice, any Odyssey manufactured in 2018 or later should have the 10-speed unit, regardless of trim level. If you’re shopping used, confirm the year and verify the transmission through the window sticker or the vehicle identification number (VIN) details.
How to verify in a used Odyssey
Verification checklist
Use the following steps to confirm the transmission type before purchase.
- Check the window sticker or listing notes for “10-speed automatic” or “10AT” in the drivetrain specification; cross-check the VIN with Honda’s data if possible.
- Inspect the vehicle’s history and service records for transmission work or ATF fluid changes, noting the recommended Honda ATF (DW-1) guidelines.
- Take a thorough test drive to assess shifting: smooth upshifts and downshifts without slipping, hesitation, or abrupt clunks, especially at highway speeds and during acceleration.
- Consult the dealer to verify the specific transmission code from the build sheet if there is any doubt about the year or regional specs.
Conventional wisdom for buyers: a 2018‑present Odyssey with the 10-speed auto should deliver smoother shifts and better highway efficiency than earlier generations, but always confirm the exact build before purchase.
Why Honda switched to 10-speed in the Odyssey
Honda moved to the 10-speed automatic with the 2018 redesign to improve acceleration feel, refinement, and fuel economy across a broad powertrain strategy. The wider gear ratio spread helps the 3.5-liter V6 operate more efficiently in a minivan, delivering quieter cruising and better overall performance in both city driving and highway merging.
Summary
Since the 2018 model year, Honda Odysseys have used a 10-speed automatic transmission across all trims, with older models relying on smaller multi-speed automatics. When shopping, verify the model year to ensure the presence of the 10-speed unit, and use the VIN or window sticker to confirm transmission details. This check helps ensure you’re getting the efficiency and smoothness associated with the 10AT in the Odyssey lineup.
