Swapping a TREMEC TKX 5-speed Transmission in Place of a Toploader 4-speed in a 1966 Ford Mustang

Swapping a TREMEC TKX 5-speed transmission in place of an original Ford Toploader 4-speed is an easy process that transforms the way a classic car drives and feels. For this article, we photographed the transmission upgrade on a 1966 Mustang, which is a great example of how the compact TKX was designed for easy fitment in early Pony cars and muscle cars. The Ford Toploader was one of the best factory 4-speeds you could get during the muscle car era. But it is easy to see how the overdrive, increased torque capacity and improved shift feel in the modern TREMEC TKX 5-speed is a great upgrade.

Choosing the Right Clutch to Go with Your TREMEC Transmission

Choosing the correct clutch for your car or truck is crucial for getting the best performance and driving experience with your TREMEC 5- or 6-speed manual transmission. With a clutch not suited for your car or truck’s powertrain and driving conditions, you’ll end up with not just a poor driving experience, but also increased risk of breaking drivetrain components. In race situations increased risk of clutch failure at a crucial moment that could cost you a victory. The wrong clutch means when you try to shift your own gears all you’re going to get is a grinding reverberation though the shifter followed by some choice expletives.

Improve Jeep and 4×4 Performance with the TREMEC TR-4050 5-speed Manual Transmission

The Jeep Wrangler is an iconic off-road vehicle. But through the years, the various models haven’t always had the best manual transmissions. For example, the Jeep YJ (1987-1995 model years) and Jeep TJ (1997-2006) lacked a decent First gear ratio, and owners found the transmissions to be less durable once larger tires and weight were added to the Jeep, including heavier axles and other off-road equipment. The factory NSG370 6-speed transmission found in the Jeep JK (2007-2018) was better, but there was still room for improvement in the eyes of Wrangler enthusiasts. The superior First gear ratio and incredible strength of the TREMEC TR-4050 5-speed manual transmission has made it a desirable upgrade not only for the Jeep Wrangler, but also many other light trucks and 4×4 SUVs.
