Ford Racing Tremec TKX-600 5 Speed Transmission .81 Overdrive

If you're looking to swap a modern, robust 5-speed manual transmission into your classic Ford or custom build, the Ford Performance by TREMEC TKX-600 is a solid choice. This transmission is built to handle serious power and offers improved drivability over older 4-speed units. It's the same heavy-duty 5-speed manual transmission that was originally used in the 1995 Mustang Cobra 'R' models, which came equipped with the 351 5.8L engines, so you know it's built for performance.

The TKX-600 features a 26-spline input shaft and a 31-spline output shaft, making it compatible with a wide range of clutch and driveshaft setups. Inside, you'll find gears made from 4615 steel, known for its strength and durability under load. The included billet aluminum shifter is not only strong but also provides a precise feel when shifting gears. This transmission holds 2.7 quarts of fluid, and its .81 overdrive gear ratio is perfect for lowering cruising RPMs on the highway, making your vehicle more fuel-efficient and comfortable on long drives.

This transmission is a popular upgrade for enthusiasts looking to modernize their drivetrain. While it's designed for a direct fit in many applications, it's always a good idea to check specific crossmember and linkage requirements for your particular vehicle or custom build. Ensure you have the correct fluid and follow the manufacturer's recommendations for break-in procedures to get the most out of this well-built transmission.
