What is a PerfectFit Kit and why is it so important?

Silver Sport Transmissions' PerfectFit™ Kits have many benefits and addresses many of the concerns you may have regarding the installation of a TREMEC 5 or 6-speed or A41 Automatic into your classic car, street rod, or truck. The PerfectFit kit will retrain the original factory look of your vehicle. We are able to do that by:

• Maintaining the correct shifter location
• Having the correct shifter stub angle and height
• Crossmembers that keep the transmission at the proper driveline angle while providing plenty of exhuast clearance
• Complete kits and instructions to make installations as simple as possible

Shifter Location - not all cars have the shifter inteh same place inside the car. PerfectFit provides over 15 unique shifter locations that will satisfy any requirement of your build. Custom variations are also possible with your supplied measurments.

The STX Shifter® mechanism is compact and requires little clearance to fit. The shifter action is tight, crisp, and has a short throw. The shifter stub angle and height is engineered to duplicate the factory shifter angle and height for a clean installation.

Driveline Angle - Each package is engineered to maintain the driveline angle specifications. You'll enjoy smooth highway driving with no vibrations.

Transmission Tunnel Clearance - Every PerfectFit™ model receives custom case machining to eliminate or greately reduce tunnel modifications. If tunnel mods cannot be eliminated, we supply you with a guide on how to modify your tunnel along with a pre-engineered and ready-to-use patch panel that can be welded or riveted into place.
