FLINT, Mich. -- General Motors Co.'s medium-duty commercial truck business has gone away.

The production finale was planned for Friday morning after the Detroit automaker shuts down an assembly line inside the Flint Truck Assembly plant.

Thirty-six-year plant worker Richard Smith drove the final truck off the line.

UAW Local 598 Chairman Dana Rouse said Smith has worked on the commercial truck line since it moved to Flint from a GM plant in Janesville, Wis., in 2002.

GM in June told nearly 400 Flint Truck workers their jobs on the commercial truck line were being eliminated after the automaker failed to sell the money-losing business.

A larger assembly line that makes heavy-duty Chevrolet Silverado and GMC Sierra passenger trucks remains inside the plant.

The commercial truck line employed nearly 400 United Auto Workers members who may be able to transfer depending on their seniority.

Union leaders said some of the displaced workers could be returning to the plant to make the heavy-duty Silverado and GMC Sierra.

The Flint Journal reported that GM built 22,151 commercial trucks, GMC TopKicks and Chevrolet Kodiaks, at the Flint plant last year.
