Lubrication & Technology of Automotive Transmissions

E-learning This course can be adapted to virtual classroom mode

Who should attend?

  • This course provides a technical overview on all automotive mechanical transmissions components and their operation. It gives information on all types of lubricants used and their classifications and specifications according to the type of transmission.
  • The course also presents information on the specificities of some manufacturers concerning the lubricants to be used.
Public :
  • Engineers and technical staff involved in the recommendations, sales and technical follow ups of automotive transmission lubricants in different areas of activities and to engineers and technicians of the automotive industry.

Level : Foundation
