AMC owners rejoice! If you’re the owner of a machine from Kenosha’s finest carmaker, Silver Sport Transmissions can help get your Javelin, AMX, Rebel, or almost any AMC into the 21st century.

Silversport’s Tremec TKX 5-Speed PerfectFit Kits for AMC are the simplest and most cost-effective way to convert to a modern overdrive with proven case machining techniques and compact shifters that provide the best fit and shift quality available. Silver Sport Transmissions CNC machines the Tremec TKX case and tailhousing to streamline the case as much as possible and also move the shifter position into the factory-correct location for a PerfectFit.

What is a PerfectFit Kit?

PerfectFit is a Silver Sport Transmissions exclusive that provides multiple benefits and addresses many concerns regarding the installation of a Tremec TKX, Magnum, or SST A41 into your classic car, street rod, or classic truck.

• Proper appearance – PerfectFit replicates factory shifter positioning, stub angle, and height.
• Better fit – PerfectFit case refinement eliminates or greatly reduces tunnel modifications.
• Smoother drive – PerfectFit kits maintain driveline angle specifications for a vibration-free road trip.
• Complete kit – Installation hardware and detailed instructions are included. Full tech support is available when the wrenches begin to turn.

What is a RestoFit Kit?

RestoFit is another SST exclusive. Some cars didn’t come with manual transmissions. Some did, but cannot accommodate the TREMEC Magnum 6-speed within the console. The RestoFit Kits have a finished look and look like they could have rolled right off the production line, even though they do not retain the factory appearance.
