Acura MDX Transmission Fluid: Change Interval
Compiled & reviewed by Nikolai Tsyrenov · Updated 2026-07-02
When to change the transmission fluid on a 2022-2025 (4th gen; Type S from 2022) Acura MDX.
In short: Acura MDX transmission fluid: Per Maintenance Minder; commonly ~50,000-60,000 mi for the 10-speed.
| Transmission Fluid interval | Per Maintenance Minder; commonly ~50,000-60,000 mi for the 10-speed |
|---|---|
| Engine / drivetrain | Base 3.5L J35 V6 (TIMING BELT); Type S 3.0L turbo V6 (J30, TIMING CHAIN); both 0W-20, 10-speed auto, SH-AWD |
| Model years | 2022-2025 (4th gen; Type S from 2022) |
Why it matters: Transmission fluid lubricates and cools the gearbox. "Lifetime fill" really means "lifetime of the warranty" — heat from towing, hills and stop-and-go traffic ages it much faster.
A drain-and-fill (not a flush) is the safe approach, especially on higher-mileage cars. Use ONLY the exact fluid spec for your transmission — the wrong fluid can ruin a CVT or automatic.
Acura MDX note: The two engines differ fundamentally: the base J35 V6 has a TIMING BELT needing ~105k-mi replacement (interference), while the Type S 3.0L turbo V6 uses a maintenance-free chain. Know which you have.

Per Maintenance Minder; commonly ~50,000-60,000 mi for the 10-speed.
Should I flush or drain-and-fill the transmission on a Acura MDX?
