DETROIT (AP) -- General Motors plans to invest $332 million into four factories in three Great Lakes states to build new, more efficient engines and transmissions.
GM says the spending at plants in Toledo, Ohio; Bedford, Ind.; and Flint and Bay City, Mich., will allow the company to build a new V-6 engine, a new small motor and new eight-speed automatic transmissions.
The company also added $46 million to a prior investment at plants in Romulus and Saginaw, Mich. to build the new V-6.
No jobs will be added, but GM says the investments preserve 1,650 jobs at the six factories.
The investment also will help GM build more six-speed automatic transmissions as auto sales continue to rise in the U.S.
