This gearbox is a factory-remanufactured unit that transfers engine torque through a continuously variable transmission (CVT) to the drivetrain. It manages the ratio between the input shaft from the engine and the output shaft to the final drive, allowing stepless speed changes under load. A worn or failing gearbox typically produces abnormal noise, gear slippage, or loss of power transmission. Because it is remanufactured to the original manufacturer's specifications, the internal clearances and hydraulic control pressures match the original assembly, ensuring correct engagement timing and shift response. A deposit is required on purchase; the deposit is refunded when the used core is returned.
