Common CVT problems include shuddering, whining or droning, overheating, and hesitation. Because CVTs use a belt-and-pulley design and a specific fluid, they are sensitive to fluid condition and heat. Symptoms should be diagnosed promptly, as CVT repairs can be more specialized than conventional automatics.

This guide is part of our common problems guide. For pricing, see the transmission repair cost guide.

What are the signs of CVT trouble?

  • Shuddering or shaking, especially under acceleration
  • A whining or droning noise that rises with speed
  • Hesitation or a delayed response
  • Overheating during normal driving

How do you care for a CVT?

CVTs are fluid-specific and often have their own, sometimes shorter, service interval. Using the exact specified fluid and servicing on schedule is the best way to protect one. See maintenance and fluid intervals.
