Traxxas Pro-Built 2-Speed Transmission - 5691A

The Traxxas TRX5691A Pro-Built 2-Speed Transmission is a factory-assembled gearbox unit designed as a direct-fit upgrade or replacement transmission for compatible Traxxas RC vehicles. Unlike a bare parts kit, the Pro-Built designation means the transmission arrives fully assembled and ready to install, saving significant bench time. The 2-speed design gives the vehicle a low gear for torque and acceleration and a high gear for top-end speed, making it a meaningful mechanical upgrade over a single-speed setup where supported.
