A transmission module, through seven steps, starts life in Ontario as scrap metal and goes back and forth across the border seven times. This is a summary of that journey

Step One: Linamar, an auto parts maker in Guelph, has scrap metal on site and it sends that scrap to a smelter in Pennsylvania.

 

Step Two: Steel from that smelter and others is then sent to an Ohio company to make a part called a hub.

 

Step Three: The hub is then sent back to Linamar in Guelph where that hub is assembled into another part, a clutch plate for example, to be used in transmission assembly. 

Four: Guelph receives from another supplier in Illinois parts also used in this assembly process. Linamar’s Ontario factory also imports aluminum housings from its foundry in Mexico’s Coahuila state. It assembles all these parts into a module.

Five: Linamar sends its parts to a plant in the midwestern U.S. where they are part of the assembly of transmissions. (This is F on the map)

Six: Transmissions are sent from the Midwest plant to an Ontario vehicle assembly plant (not Linamar) where they are put in vehicles. 

Seven: Those vehicles return to the U.S. some stay in Canada of course,  for sale on dealer lots.
