TIPTON, Ind. (AP) — Chrysler is set to mark the opening of a new transmission plant in central Indiana where hundreds of people are expected to eventually be working.

Chrysler officials say company CEO Sergio Marchionne (SEHR'-jee-oh mahr-kee-OH'-nay) will join several local officials for the ceremony Tuesday afternoon at the factory near Tipton.

Chrysler last year acquired the massive factory along U.S. 31 that German auto parts maker Getrag started building in 2007. The automaker said it would spend about $160 million to finish the vacant factory where it expects to have up to 850 workers.

The automaker started this spring testing new transmissions assembled at the Tipton factory.

The new factory joins four Chrysler plants in nearby Kokomo, giving it more than 7,000 hourly employees in the area.
