Chevrolet will offer a 10-speed, fully automatic Allison transmission in its 2020 Silverado 2500/3500 HD trucks. The 2020 Silverado HD will debut in February.
“We built the new 2020 Silverado HD with more differentiation than ever before, to meet the needs and priorities of our customers,” said Jaclyn McQuaid, chief engineer, Silverado HD. “By offering the new Allison 10-speed, tested and validated in partnership with Allison Transmission, each transmission will deliver the legendary quality and durability that customers have come to expect.
The Allison-branded automatic transmission, manufactured by General Motors, combines enhanced performance and fuel economy, greater operational flexibility, and improved driver comfort and control, with an industry-leading reputation for uptime and reliability, according to the companies. The Allison 10-speed transmission will be coupled with Chevrolet's Duramax diesel engine.
"We are pleased that General Motors continues to expand the range of Allison products available for their customers with the 2020 Silverado HD," said Randy Kirk, senior vice president of product engineering and program management for Allison Transmission. "Allison Transmission and GM have a long history of collaboration and innovation."
Recently, Allison began producing the 6-speed fully automatic transmission for Chevrolet’s Silverado 4500 HD, 5500 HD, and 6500 HD medium-duty trucks.
