As part of the acquisition agreement, Tenneco Automotive is acquiring nearly all the assets of Gabilan Manufacturing but not the name, real estate at Salinas, California, its discontinued farm equipment or other businesses or certain liabilities associated with the exhaust business.


Tenneco Automotive will lease the facility in Salinas and will assume the current leasing agreements at the other Gabilan facilities.


The business has about 240 employees, the majority of which are located at the California headquarters and main manufacturing facility in Salinas. The company also operates three other facilities in Lincoln, Nebraska, Milwaukee, Wisconsin and Emigsville, Pennsylvania.
