TREMEC TKX & TREMEC Magnum for Mustang & Cougar 1969-1970

Silver Sport Transmissions has the best-engineered kits to continue the evolution of your 1969-1970 Ford Mustang or Mercury Cougar. Our PerfectFit™ Kits bring the shifter handle to the factory-correct position for the best possible fit and our billet shifter tower provides short, crisp shifts.

Car shows, close friends, and good times are all within easy reach when you choose a TREMEC TKX 5-speed or T56 Magnum 6-speed from SST!

The TREMEC TKX 5-Speed is the newest and most compact transmission from TREMEC.  Capable of handling up to 600 lb-ft torque and 7,500 rpm shifts, the TKX is strong enough to handle most street applications. Our TKXs have been modified to give you a factory-correct shifter position so your car will retain the factory look. Find out why people call this powertrain upgrade the best improvement they've made to their car! 

The TREMEC Magnum 6-speed is quickly gaining in popularity as more and more people opt for larger engines. The 6-speed has two overdriven gears and can handle up to 700 lb-ft torque and 7,800 rpm shifts. Although it's certainly capable of handling the abuse of the track, it's also great for everyday use.  Our short throw shifter tower turns a great transmission into one of the best out there and our PerfectFit™ kit will let you keep a factory look with modern performance.
