Product Spotlight: Richmond 4-speed Super T10 and T10 Plus transmissions. The original performance transmission! Both the Super T10 and the T10 Plus have been re-engineered for the demands of modern torque-hungry engines. They are light, but strong, at just 70lbs. Our 4-speed transmissions can handle a great amount of torque. A four speed countershaft helical gear transmission, the Super T10 is synchronized in all forward gears. First and reverse are "constant mesh" to prevent gear clash, while strut-type synchronizers provide longer life and easier shifting. For even higher performance, the T10 Plus combines upgraded brass race synchro assemblies and a billet front bearing retainer with race proven technology to deliver the smoothness and strength needed for the demands of the road course.
