5-speed gearbox with reverse, featuring a fully visible differential system. Designed for automotive training, it allows manual gear selection through a crank handle, demonstrating the mechanics of gear synchronization, reverse shaft operation, and the differential’s planetary gear system. The trainer includes a professionally sectioned and color-coded design, with chromium-plated and galvanized parts for durability, allowing students to observe key components like the main shaft, synchronizing rings, and bearings in real-time operation.
