Equipping a classic GM muscle car with a replacement transmission? You won't want to trust the upgrade to aftermarket parts. Genuine OEM gearboxes will work best under the hood, as they're factory replacements, designed and built by Chevy to do the all-important job of shifting. If you're looking to get the most out of a drive, though, consider installing a Muncie four-speed transmission. It's one of the most popular manual transmissions of the seminal 1960s, when sports cars were coming into their own. You can pick up parts for one here at Classic Muscle -- everything from reverse idler shafts and gears to detent cams and bearings -- and at sale prices.

Muncie Four-Speed Transmission Parts for Sale | Shop a Complete Online Catalog

We carry plenty of other classic Chevy transmission parts for cars and trucks from other eras as well. If you want to find what you've been in search of more quickly and easily, though, just search its part number. Buy now, and we'll ship your order fast, to any address in the US. Have any questions?
