Two 10-Speeds, One Goal, Different Keys: Ford's 10R80 vs GM's 10L80
Ford’s 10R80 and GM’s 10L80/10L90 share hardware but run different software and internal components, so they’re not interchangeable. Ford’s 10R80 debuted in the 2017 F-150; GM’s 10L80 arrived in the 2016 Camaro ZL1. Both have had reliability issues and recalls (Ford with CDF-drum shifting and related fixes; GM with shudder/lockups and valve-body issues), illustrating distinct implementations of a common 10-speed goal.
