Watch as I assemble a 13 speed transmission back box. This video will show you how to add your reference marks on the gearing of the auxiliary section of the transmission to correctly re assemble the unit. There are many part numbers included in this tutorial. This was a customers unit that I tore down and repaired. This unit was wore out with multiple issues regarding grinding while making splits and range shifts. In the video I replace the synchronizer,bull gear,splitter gear and more.If you have the time and a couple of tools you can easily complete this job without any problems. This 13 speed was in a Freightliner Coronado @etrtruckcenterenginedrivet8918
