General Motors continues investing in the expansion of its SUV and truck lineup with an announcement regarding its propulsion plant in Romulus, Michigan.

GM will inject $20 million into the facility to increase capacity for future 10-speed automatic transmission production. The plant currently builds V6 engines and 10-speed transmissions used in several GM cars, trucks and crossovers.

The new investment will go towards purchasing additional machining equipment that will enable the plant to build more 10-speed automatic transmissions. While the automaker did not disclose specifics or timing related to the plant’s future products, the announcement comes only a day after GM said it would invest $36 million into Lansing Delta Township for future crossover production.

Furthermore, GM also announced last week the addition of 1,000 jobs for truck production at its Flint Assembly Plant, also in Michigan.

“GM’s investment in Romulus will enable the plant to continue playing an important role in our core business going forward,” said GM Chairman and CEO Mary Barra during a visit to the plant.

GM has invested more than $880 million at the Romulus plant since 2009. Currently employing about 1,350 people, the plant originally opened in 1976 as part of GM Detroit Diesel Allison Division, making diesel engines and components.

GM started making engines at Romulus in the 1980s, with the plant producing over 10.8 million V8 engines and over 6.6 million V6 engines since its inauguration.

The announcements regarding new investments in U.S. plants come just as General Motors is preparing to stop production at four other facilities in the country. On March 1, GM will stop making cars at the Detroit-Hamtramck Assembly plant, which currently builds the Buick LaCrosse, Cadillac CT6, Chevrolet Impala, and Chevrolet Volt.

Around the same date, GM is expected to pull the plug on Lordstown Assembly, which makes the Chevrolet Cruze. Activity at Baltimore Operations will stop on April 1 while Warren Transmission Operations will stop production on August 1. In addition, GM’s plant in Oshawa, Ontario will go down in the fourth quarter of this year.
