The whole transmission is wrapped with salt‑spray resistant moisture‑proof film and shock‑resistant foam, firmly fixed inside fumigated wooden crate to avoid collision and rust during long ocean transit. All openings are sealed with brand‑new protective plugs. We can send detailed product photos before shipment. Suitable for sample evaluation and small‑batch stocking for repair workshops. Bulk order lead‑time varies subject to stock status and workshop production load.

This is remanufactured assembly, torque converter, gasket kits and oil pan can be ordered separately. Installation must follow OEM requirement for transmission fluid type. Damage caused by wrong oil, bad cooling system or improper installation will not be covered. Submit VIN or OEM part number so we verify exact compatible unit for you.
