When to change the transmission fluid on a 2019-2024 (6th gen L34) Nissan Altima.

| Transmission Fluid interval | CVT (NS-3): listed inspect; replace ~60,000 mi severe. Strongly recommend ~30,000-60,000 mi given CVT history. |
|---|---|
| Engine / drivetrain | 2.5L NA (PR25DD) or 2.0L VC-Turbo; 0W-20 synthetic; Xtronic CVT (NS-3) |
| Model years | 2019-2024 (6th gen L34) |
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.
Nissan Altima note: Nissan Xtronic CVTs have a reliability reputation — proactive CVT fluid changes (~30k-60k) and keeping the CVT cool materially help. This is the #1 maintenance story for this model.
FAQ
How often should you change the transmission fluid in a Nissan Altima?
CVT (NS-3): listed inspect; replace ~60,000 mi severe. Strongly recommend ~30,000-60,000 mi given CVT history.
Should I flush or drain-and-fill the transmission on a Nissan Altima?
