New Mechanical Shifting Devices in Automotive Transmissions Web Seminar RePlay

Course code: PD331711ON

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.


By participating in this course, you’ll be able to:

  • Recognize a One Way Clutch (OWC) and state its basic function in Automatic Transmissions
  • Explain the fundamental construction of a Controllable Mechanical Diode (Controllable One Way Clutch)
  • Explain the basic function of the CMD
  • Explain the value proposition of the CMD
  • Give examples of likely future applications of the technology
