This course was designed to cover power train components, their construction, and operation. It is designed to enable the participant to become familiar with maintenance, repair, and diagnosis of power train elements.
Our teaching methods include heavy class participation, visual aids, texts, and actual components. Our instructors have many years of experience and take a non-intimidating, no-nonsense approach in their presentation. Attendees should bring note-taking material.
