Abstract
The disclosure is directed to a method for use in a machine having a transmission having an operational mode, and including first and second power source paths, and a combined power output. The first power source path includes a variator. The method of controlling the transmission includes operating the first power source path, providing a signal indicative of the operational mode of the transmission to a controller, and at least partially neutralizing the variator if the signal indicates that the transmission is in neutral for at least a preset period of time.
