OE NO. : V4A51 V73 V46, R4A51 V4A51. Acting as a fluid coupling, it effectively dampens engine vibrations and prevents stalling when the vehicle comes to a complete stop in traffic. The torque converter allows the engine to operate at optimal RPMs while the vehicle remains stationary, reducing wear on drivetrain components and engine mounts. By absorbing torsional vibrations and shock loads, the torque converter protects sensitive transmission gears from damage during aggressive acceleration events. Without moving mechanical contact during normal operation, torque converters offer exceptional durability and require minimal maintenance over the vehicle's lifetime., Manufacturer: NADCFN
