When should you change your transmission fluid?
Intervals vary widely — from ~30,000 miles for some automatics to 'lifetime' (really ~60,000–100,000) for others. Check your model below.
Why it matters: Degraded transmission fluid causes harsh shifts and is a leading cause of expensive transmission failure.
Change Transmission Fluid by model
| Toyota Camry (2018-2024 (XV70)) | 8-speed auto is 'fill for life'; severe-use drain-and-fill ~60,000 mi |
|---|---|
| Toyota Corolla (2020-2024 (E210)) | CVT (Direct-Shift) — long-life/inspect; drain-and-fill ~60,000 mi under severe use |
| Toyota RAV4 (2019-2024 (XA50)) | 8-speed auto (gas) long-life; drain-and-fill ~60,000 mi reasonable. Hybrid eCVT uses Toyota ATF WS, inspect |
| Honda Civic (2016-2025 (10th-11th gen)) | CVT fluid (Honda HCF-2) — proactive change ~30,000-50,000 mi recommended |
| Honda CR-V (2017-2024 (5th-6th gen)) | CVT (HCF-2), Minder-triggered; proactive ~30,000-50,000 mi |
| Honda Accord (2018-2025 (10th-11th gen)) | 1.5T = CVT (HCF-2), proactive ~30k-50k; 2.0T = 10-speed auto, drain-and-fill ~60,000-90,000 mi |
| Ford F-150 (2021-2024 (14th gen)) | 10-speed: ~150,000 mi normal; severe/towing ~60,000 mi |

| Nissan Altima (2019-2024 (6th gen L34)) | CVT (NS-3): listed inspect; replace ~60,000 mi severe. Strongly recommend ~30,000-60,000 mi given CVT history. |

| Subaru Outback (2020-2024 (6th gen)) | CVT 'fill for life' (no leaks); many indies change ~60,000-100,000 mi as insurance |
| Hyundai Elantra (2021-2024 (CN7 7th gen)) | IVT (CVT) inspect / no normal-interval service; DCT (N-Line) fluid inspected ~96,000 mi |
| Mazda CX-5 (2017-2024 (KF gen)) | Conventional 6AT — inspect/replace ~60,000 mi (not 'lifetime' CVT) |
| Tesla Model 3 (2017-2024 (EV — no engine maintenance)) | N/A — single-speed gearbox, no scheduled owner service |
| Volkswagen Jetta (2019-2024 (MK7 / A7)) | 8-speed auto fluid service ~80,000 mi; GLI DSG (DQ381) fluid ~40,000 mi |
