A continuously variable transmission: A) Can use the same fluid as any other automatic transmission
B) Needs transmission fluid exchanges much more frequently
C) Requires a transmission fluid specially formulated for CVT needs
D) Is the same as a step-gear transmission

A continuously variable transmission (CVT) is an automatic transmission that can change seamlessly through a continuous range of gear ratios. This contrasts with other transmissions that provide a limited number of gear ratios in fixed steps. The flexibility of a CVT with suitable control may allow the engine to operate at a constant RPM while the vehicle moves at varying speeds.that means the ans is A.

the warning light flashes for a second or two when the engine starts. if it stays on, there's must be something wrong with the coolant. you should never dare to continue driving when the light is on. pull over as soon as possible and shut the engine off.

hope this is what you're talking about
