Continuously variable transmissions (CVTs) offer enhanced fuel efficiency over traditional automatic transmissions, making them increasingly popular choices for both passenger cars and in off-highway applications in Japan, China and the U.S.
There are two main types of CVTs, belt or chain type, with similar lubrication needs. Since they both generate high metal-to-metal friction performance, they require unique metal friction performance, making them very different from a traditional stepped automatic transmission.
Continuously variable transmission fluids must provide:
✓ Shear stability
✓ Low temperature fluidity
✓ Wear and oxidation protection
✓ Anti-shudder durability
✓ High metal-to-metal friction performance
Working closely with OEMs and having a deep understanding of CVT performance requirements has enabled Lubrizol to develop fluids that maintain or enhance metal friction performance while boosting anti-shudder durability. We have developed the first fluid in the marketplace that will work on both belt and chain CVT configurations.
