DETROIT—General Motors Co. said Feb. 19 that it is investing $20 million at a suburban Detroit powertrain plant to increase production of 10-speed automatic transmissions.
The investment will be used to "purchase additional machining equipment that will enable the transmission capacity expansion" at Romulus Powertrain, according to GM.
The company, citing competitive factors, declined to provide exact timing of the investment, which was expected to be announced at the plant by GM CEO Mary Barra.
"GM's investment in Romulus will enable the plant to continue playing an important role in our core business going forward," Barra said in a statement.
No new jobs are expected to be created as a result of the investment, GM said. The facility employs roughly 1,350 people, including 1,300 hourly United Automobile Workers members.
UAW Vice President Terry Dittes in a statement said the union "fully supports" the move.
"We in the UAW look forward to more investments like this in the future so GM can build where they sell," he said.
GM increasingly has been adding the 10-speed automatic transmission to its lineup of rear-wheel-drive vehicles. The transmission debuted in the 2017 Camaro ZL1, and has since expanded to the auto maker's full-size pickups and SUVs as well as the Cadillac CT6 and upcoming heavy-duty pickups.
