A continuously variable transmission (CVT) uses a belt or chain and pulleys instead of fixed gears, and it relies on a special fluid. Clean fluid is critical to CVT longevity, so regular service pays off.

Typical interval
Many manufacturers recommend changing CVT fluid every 30,000 to 60,000 miles, though some list longer intervals or call the fluid 'lifetime.' Because CVTs are sensitive to fluid condition, many technicians favor changing it on the shorter end. Follow your owner's manual.
Use only the exact CVT fluid specified for your vehicle
Never substitute regular ATF for CVT fluid
Use the correct fluid
CVT fluid is not interchangeable with standard automatic transmission fluid. Using the wrong fluid can cause slipping and permanent damage, so match the manufacturer's exact specification.
Severe-service driving
Stop-and-go traffic, towing, heavy loads, and hot climates raise fluid temperature and can call for shorter change intervals. If your driving is demanding, use the severe-service schedule in your manual.
Warning signs
Shuddering during acceleration, slipping or a delayed response, whining noises, overheating warnings, or a burnt fluid smell can indicate the fluid is degraded or the CVT needs attention. Address these early, since CVT repairs are expensive.

❓ FAQ
Do CVT transmissions need fluid changes?
Yes. Even when called 'lifetime,' CVT fluid degrades and CVTs are sensitive to fluid condition. Many owners change it every 30,000 to 60,000 miles per the manual.
Can I use regular ATF in a CVT?
No. CVT fluid is specialized and not interchangeable with standard automatic transmission fluid. Using the wrong fluid can cause slipping and permanent damage.
What are the signs of CVT problems?
Shuddering during acceleration, slipping or delayed response, whining, overheating warnings, or a burnt smell. Address these early because CVT repairs are costly.
Does towing affect CVT service?
Yes, and many CVTs are not rated for heavy towing at all. Demanding use raises fluid temperature, so follow the severe-service interval and your vehicle's tow rating.
Is CVT fluid a drain-and-fill or a flush?
Many CVTs use a drain-and-fill procedure with a precise refill amount and fluid-temperature check. Follow the manufacturer's exact procedure.
