339-8229 Functions of Hydraulic Gearbox Repair Kit

339-8229 

A hydraulic gearbox repair kit is a complete set of special accessories for overhauling the hydraulic system of automatic transmissions. It contains various oil seals, sealing rings, piston rubber gaskets, washers, filter screens, dust rings and other sealing consumables. It is mainly used to replace worn and damaged sealing parts inside gearboxes. After long-term vehicle operation, sealing components tend to harden and crack, leading to hydraulic oil leaks, unstable oil pressure, jerky shifts, slipping power, sudden power loss and abnormal temperature rise in the transmission.

The kit enables full replacement of aged seals at one time to stop oil leaks and rebuild steady hydraulic pressure for normal operation of valve bodies, clutches and brakes. The matched filter screens remove impurities from fluid to prevent valve body jamming, restore smooth shifting and extend transmission service life. It cuts costs of purchasing individual spare parts separately and suits both major overhauls and emergency leak repairs, serving as essential supplies for hydraulic transmission maintenance.
