Why Everyone THINKS They Had an M22… But Almost Nobody Did!

A forgotten twelve-dollar part inside GM’s TH400 transmission — the governor — turned mild Buicks and Chevelles into street monsters. This small aluminum housing with weights and springs controlled shift points, and hot rodders in the 1960s learned that trimming grams or swapping springs delayed shifts and unleashed big-block power at high RPMs. Cheap, reversible, and easy to tune, it became the secret weapon of sleeper cars, creating legends from grocery-getters. Even today, builders mix old-school physics with modern tools, proving that this humble piece remains one of GM’s most underrated performance tricks in muscle car history.
