The Controllable Mechanical DiodeTM (CMD) is a new technology that improves fuel economy, mass and packaging in modern automatic transmissions. In this 40-minute course, participants will gain an understanding of the base construction, function and value of the new Controllable Mechanical DiodeTM innovation. Advantages of its use in new automatic transmissions will be explained along with examples of the CMD’s alignment to electrified transmissions.

Today's vehicles apply the primary function of a transmission: to couple the engine to the driveline and provide torque ratios between the two. How is this achieved? This eLearning course will familiarize you with the operational theories and functional principles of modern vehicle transmission systems designed to achieve the most efficient engine operation. Participants will learn about current designs, the components and sub-systems used, their functional modes, how they operate, and interrelationships.
