OY1101A 0.5Ton adjustable height Transmission Jack

The OY1101A is a 0.5‑ton adjustable‑height transmission jack, designed for professional automotive repair shops, transmission specialists, and DIY enthusiasts who need to safely remove, install, and position vehicle transmissions, transfer cases, and differentials. With a maximum lifting capacity of 0.5 tons, this jack handles most passenger car and light truck transmissions with ease. The OY1101A features a specialized lifting head that is adjustable in height, allowing the operator to precisely align the transmission with the engine bell housing or crossmember. The adjustable height mechanism, typically a hydraulic ram with a foot pump or a manual screw system, provides smooth lifting over a wide range, from a low minimum height to a generous maximum height, accommodating vehicles on lifts, ramps, or jack stands.
The jack is constructed from heavy‑duty welded steel with a durable powder‑coated finish, resisting oil, grease, and workshop wear. The lifting head features a large, flat saddle with a non‑slip surface, and it includes a set of adjustable arms or a chain with a hook for securing the transmission during lifting and lowering. The saddle can be tilted in multiple directions (side‑to‑side and front‑to‑back) via independent adjustment knobs or levers, allowing fine alignment with the transmission mounting points. The height adjustment is typically achieved through a foot‑operated hydraulic pump, freeing the operator’s hands to guide the load. A built‑in overload valve prevents exceeding the rated capacity, and a precision release valve allows controlled, gradual lowering.
