Shop All Categories

Every Gearstar category in one index. Performance transmissions are grouped by make, GM, Ford and Mopar, then by model, so you can go straight to a 4L60E, 4L80E, 700R4, 200-4R, C4, C6, AOD or 727. The rest of the catalog covers torque converters, crate engines, transmission coolers, controllers, shift kits and installation parts. Every transmission is built by one technician and dyno tested before it ships.
