The Harley 6 Speed Rebuild Project is here! The Harley 6 Speed has been in service since 2006 when it was introduced to the Dyna family. Higher road speeds made this a necessity for Harley-Davidson. It has had it’s fair share of positive and negative reviews. Aftermarket companies jumped on its’ downfalls to make a better overdrive. This 83 Minute video project will show you how to rebuild your Harley 6 speed and it will provide you a great walk through if you plan to swap out for an aftermarket transmission.
