Silver Sport Transmissions' experience runs deep. Our engineering, sales and technical staff provide over 100 years combined experience, and our PerfectFit™ Transmission Kits are in more classics than any other kit on the market.

Silver Sport Transmissions, an Elite Distributor of TREMEC® Transmissions, is the industry leader in the research and development of kits to modernize the drivetrain of classic cars, trucks and street rods. Our SST A41 Automatic, TREMEC TKO and T5 5-Speeds, and TREMEC Magnum 6-Speed PerfectFit and RestroFit® Kits are the best fitting and most complete kits available.

Kit components are unique to each application and are made to last using only the highest-grade parts. Our transmissions are modified to achieve the correct shifter location and minimize tunnel interference and are quality checked for leaks, noise and performance. No one else performs all the testing we do.

We believe classic cars and trucks look their best on the open road, so we will continue to innovate and develop the best performing, fitting, and durable products to bring your classic “up to speed”.
