Allison Transmission to close Sommariva Perno plant, 180 jobs

US transmission maker Allison Transmission, the new owner of the former Dana plant in Sommariva Perno, announced on 16 September 2026 the closure of the site: all production and the 180 employees are to be moved to the Rivoli (Turin) plant about 50 km away. FIM-CISL, FIOM-CGIL and UIL call the decision 'unacceptable' and point out that during talks at the industry ministry MIMIT the company had assured that no Italian site would be closed; an eight-hour strike was held outside the plant on 17 September 2026 (Quotidiano Piemontese, 17 September 2026). Update (22.09.2026): Industry minister Adolfo Urso ordered a formal review of whether Allison is complying with the golden-power conditions attached to its purchase of the plant, and summoned the company to the ministry; Senator Giorgio Maria Bergesio had previously tabled a parliamentary question (Cuneo24, 22.09.2026: https://www.cuneo24.it/2026/09/golden-power-sulla-ex-dana-graziano-il-ministero-convoca-allison-transmission-360613). Update (02.10.2026): At a meeting at the Unione Industriale in Turin, Allison and the unions Fim, Fiom and Uilm signed a minute suspending the transfer of the 180 workers to Rivoli: while talks on alternatives for the Roero site continue, the company may not move staff or machinery and the unions have suspended strikes (Grugliasco24, 02.10.2026).
