New transmission designs from various OEMs have become an integral part of the vehicle market. Transmission designs such as the push belt drive continuously variable transmission (CVT), the tension belt CVT and the traction (toroidal) drive CVT represent some of the latest technologies that may demand unique performance characteristics form the lubricant. At the same time, more conventional automatic transmissions (AT) continue to demand lubricant enhancements into the foreseeable future. In some cases, the tack taken by the automobile manufacturer is to require that one lubricant be applied to both continuously variable transmissions and automatic transmissions; while, other manufacturers require more specialized fluids for both. The performance demands as well as desired enhancements provide a useful topic of comparison and contrast from both advancements made to improve current fluid types and to address new transmission designs. In doing so, it is possible to see the dramatic effects that the choice of additive has in performance tests used for transmission fluid development and approval.
