This 6-piece electric valve body seal kit features three universal part numbers: 24107536339, 24347588725, 24347588724. It is specifically designed for ZF 6HP19 and 6HP21 automatic transmissions and is compatible with BMW X5, Z4, and other models equipped with these transmissions. This kit is used to refurbish the sleeve seals between the valve body and the transmission housing, addressing issues such as valve body failure, oil pressure imbalance, and jerky or slipping shifts. It is a core replacement part for transmission overhauls. All seal sleeves and sleeve plugs are molded according to the original valve body cavity slot specifications. Their external dimensions and locking arc radii precisely match the vehicle's original mounting positions. After disassembling the valve body, they can be directly inserted and installed in their original positions without the need to grind the housing or modify the parts, thereby preventing secondary damage caused by assembly gaps at the source.
Original factory seals, subjected to fluctuating transmission fluid temperatures over time, are prone to loosening and developing gaps. This directly causes internal oil pressure instability, manifesting as jerky upshifts and downshifts, delayed shifting, and occasional slippage. Replacing the entire set of seals restores the valve body's sealed chambers, stabilizes internal operating pressure, and restores smooth shifting performance. These one-piece molded rubber seals are designed to withstand the constant temperature fluctuations and operational vibrations within the transmission. Once installed, they fit snugly into the grooves and remain securely in place. The complete set includes all 6 necessary components, eliminating the need to purchase individual seals separately.
The product is shipped as a complete set. Mechanics can quickly perform a valve body seal overhaul using standard transmission disassembly tools, effectively shortening vehicle downtime and reducing the repair shop's costs for stocking individual parts. There is no need to replace the entire transmission valve body assembly at high cost; this seal kit alone can complete the valve body refurbishment, significantly reducing transmission repair costs for vehicle owners. Suitable for BMW authorized service centers and professional automatic transmission repair shops.
