Diesel - Duramax 

This course will consist of six (6) weekly zoom meetings with our registered attendees. They will be held on Zoom.  There will be an online orientation and an online assessment provided to take before the first meeting.

This coaching session, consisting of six webinar meetings, is full of information on GM Duramax diagnostics covering extensive 6.6 Duramax repair information and select tips.

Held every Thursday, this course will demo actual testing and practical service demonstrations along with helpful tips and tricks from our ASE Master Technician Instructor Tom Rayk.
