Ford Racing Tremec TKX-600 5 Speed Transmission .68 Overdrive

If you're looking to swap a modern, robust 5-speed manual transmission into your classic Ford or a custom build, this Ford Racing Tremec TKX-600 is a solid choice. This is the same heavy-duty transmission that was originally found in the 1995 Mustang Cobra 'R' models, specifically those equipped with the 5.8L 351 Windsor engines. It offers a significant upgrade in durability and performance over older 4-speed transmissions, making it ideal for a wide range of applications where you need a reliable manual gearbox.

Built with 4615 steel gears, this transmission is designed for strength and longevity, handling the demands of spirited driving and higher horsepower applications. The billet aluminum shifter assembly ensures precise and comfortable shifting. It features a 26-spline input shaft and a 31-spline output shaft, common configurations for many Ford rear-wheel-drive setups. The transmission holds 2.7 quarts of fluid and includes a .68 overdrive gear ratio, which is fantastic for lowering cruising RPMs on the highway, improving fuel economy, and reducing drivetrain noise in your vehicle.

This transmission is a popular choice for builders looking to modernize their classic Ford's drivetrain. While it's a direct replacement for certain Mustang models, custom installations will require appropriate crossmembers, driveshafts, and clutch/flywheel assemblies. It's a well-built unit that offers a significant improvement in driving experience and durability for your project.
