We’ve assembled a variety of manual gear ratio charts for General Motors vehicles that we hope can help you avoid choosing the wrong transmission only to discover your hot rod or truck is performing like a 19th-century horse-drawn chuckwagon, minus the delicous beans and salt pork.
Planning a manual transmission swap in your Chevy or GM vehicle? Double-check your gear ratios. Here’s a good start.
Anygo. [NOTE: Not every transmission in GM’s history is listed here. It is mostly Camaro/Firebird/Corvette-focused. We’re sorry if you love a particular transmission not shown on this list. We promise it wasn’t intended as any sort of slight to the excluded GM-made transmissions.]
