What manual transmission fits into a Pontiac grand prix?

The Pontiac Grand Prix, depending on the year, never offered a manual transmission as a factory option. All Grand Prix models were equipped with automatic transmissions. Therefore, fitting a manual transmission would require a significant and complex aftermarket conversion, which is not a straightforward undertaking. It would involve sourcing a compatible transmission (requiring extensive research to find one that fits the chassis and engine), custom fabrication of mounts, driveshafts, and potentially other components, as well as modifications to the clutch and pedal assemblies.
