Quick answer: A transmission fluid drain and fill typically costs $100–$250, and a fluid exchange (“flush”) costs $150–$400 at an independent shop. CVTs, dual-clutch transmissions and many European cars cost more, often $200–$500, because they need special fluid and procedures.
Transmission fluid service cost by type
Estimates updated October 2026, independent shop prices.
| Service | What it does | Typical cost |
|---|---|---|
| Drain and fill | Replaces about 30–50% of the fluid | $100 – $250 |
| Pan drop with filter | Drain, new filter and gasket | $150 – $350 |
| Fluid exchange (machine “flush”) | Replaces most of the fluid | $150 – $400 |
| CVT fluid change | Special CVT fluid, sometimes warm-up check | $150 – $350 |
| Dual-clutch (DCT) service | Special fluid, sometimes two circuits | $200 – $500 |
| Manual transmission fluid | Gear oil change | $60 – $150 |
| Dealer (any type) | Same, OEM fluid | Often 30–60% more |
How often should you change transmission fluid?
- Check your owner’s manual, especially the “severe service” schedule (towing, stop-and-go, hot climates).
- Many automatics: every 30,000–60,000 miles under severe use, or 60,000–100,000 miles under normal use.
- Many CVTs: every 25,000–60,000 miles, depending on the maker. Regular changes matter on CVTs; see Nissan CVT Problems.
- Some makers call the fluid “lifetime”, but many transmission specialists still recommend changing it around 60,000–100,000 miles.
Drain and fill vs. flush
A drain and fill is gentle and cheap, but only replaces part of the fluid, so it’s often repeated two or three times. A fluid exchange replaces almost all the fluid in one visit. On a high-mileage transmission that has never had a fluid change, some shops prefer a simple drain and fill to avoid sudden changes, while a flush done with the correct fluid and equipment is generally safe.
Signs your transmission fluid needs attention
- Fluid that is dark brown or black or smells burnt.
- Harsh, delayed or slipping shifts.
- Leaks (red or pinkish fluid under the car).
- Transmission overheating warnings when towing.
If the transmission is already slipping badly, a fluid change won’t repair it. See Is It Worth Replacing a Transmission at 150,000 Miles?
How to save money
- Use the exact fluid your manufacturer specifies; the wrong fluid can damage the transmission.
- Do it at an independent shop or transmission specialist rather than a quick-lube chain.
- Bundle it with other scheduled maintenance.
