Hey, I'm quite new to chevys and I'm wondering if the manual trannys have gears that are interchangeable. Right now I have a 4-speed with a granny gear, but I would rather have a 5 or 6 speed yet still retain the extremely low gear. Does anyone know if it's possible to take that first gear out and put it in a 5 speed or if GM ever made a 5-speed with that granny gear?
