Does GM still use Allison?
In 2020, General Motors launched its own 10-speed automatic transmission, developed in partnership with Ford, marking the end of Allison-built components inside GM trucks. The Allison badge remained as a branding gesture until now. By 2026, General Motors will stop using the Allison name altogether. Given that it’s no longer using literal Allison transmissions, GM evidently took a close look at what it’s paying for the branding and product validation and decided that at this point, probably nobody’s buying a truck or not buying one based on loyalty to a transmission supplier.
