Description

The California Pony Cars T-5 5-Speed Conversion Kit (TRA-670-534) provides the necessary components to upgrade your 1967-1970 Ford Mustang to a more modern 5-speed manual transmission. This kit is designed to integrate a T-5 transmission, offering improved drivability and fuel economy over older 4-speed systems. This conversion kit is specifically designed for use with original 6-bolt bell housings, and includes key parts such as a drive shaft slip yoke and a transmission mount. Installation requires minor modifications to the bell housing, specifically drilling one hole and tapping another. Compatibility is confirmed for specific 6-bolt bellhousing casting numbers including C3AA-6394-C and C5AA-63. When undertaking this swap, it is advised to check the fitment of the transmission mount with your existing crossmember to ensure a smooth installation. The kit is intended to streamline the T-5 swap process for classic Mustang owners seeking a more refined driving experience.
