This is a dedicated 3-gear transmission case designed for the 2WD YZ-2DTM platform. The part provides the housing for the 3G gear train and serves as the mounting point for internal driveline components on YZ-2DTM based chassis.
Use this left/right pair when replacing worn or damaged transmission housings on compatible B-YZ2DTM family models. The case is intended for RC-scale repair, routine maintenance, and setup work where the integrity of the gear enclosure affects gear mesh and drivetrain alignment.
Installation notes: check alignment and bearing fits during reassembly, verify gear mesh and freeplay before running, and inspect seals or shims you reuse from the original assembly. This component focuses on compatibility and correct fit rather than changing gear ratios, so treat it as a direct replacement for the listed chassis.
