A toothed CVT using a Cone with One Torque Transmitting Member that is coupled by a Transmission Belt to another Cone with One Torque Transmitting Member for which teeth re-engagement between the Torque Transmitting Members and their Transmission Belt is improved. Said CVT uses a slack-side Tensioning Pulley in order to maintain the tension in the slack-side of the Transmission Belt almost constant so as to ensure smooth re-engagement of the Driven Cone; and a Transmission Diameter Compensating Mechanism, which increases the Transmission Diameter of the Driving Cone when the torque being pulled by the Driving Cone is increased, in order to compensate for an increase in Transmission Belt Teeth Compression and an increase in stretching of the tense-side of the Transmission Belt, due to an increase in tension in the tense-side of the Transmission Belt when an increased torque is transmitted; to ensure smooth re-engagement of the Driving Cone.

A Cone with One Torque Transmitting Member that can be used to construct Non-friction Dependent CVT's that can be used with a Transmission Belt for which the teeth of the Transmission Belt are shaped below the belt of the Transmission Belt, such as a Timing Belt for example. In order to provide a Level Resting Place for the Transmission Belt on the conical (sloped) surfaces of its Cone, which are surfaces that are not covered by a Torque Transmitting Member or a Non-Torque Transmitting Member, the Torque Transmitting Member and the Non-Torque Transmitting Member each have a Leveling Extension. The Leveling Extension of the Torque Transmitting Member can enter and exit the Non-Torque Transmitting Member as required; and the Leveling Extension of the Non-Torque Transmitting Member can enter and exit the Torque Transmitting Member as required.
