1. Precise Vehicle Adaptation, OEM-Level Compatibility

As an exclusive valve body assembly for the transmission of specific vehicle models, the 4621026200 transmission valve body strictly complies with the technical specifications and dimensional standards of the corresponding original equipment manufacturer (OEM). The oil passage layout of the valve plate and the spool stroke parameters are completely synchronized with the hydraulic system of the original vehicle's transmission, and the interface specifications are seamlessly compatible with the Transmission Control Unit (TCU). It can be directly installed without additional modification or adjustment, effectively avoiding problems such as oil circuit misalignment and signal transmission delay that are common in non-adaptive valve bodies. This ensures that the transmission regains the original OEM power transmission efficiency, making it particularly suitable for scenarios such as replacing old valve bodies or maintenance of the corresponding vehicle model.

2. Efficient Hydraulic Control, Excellent Shifting Response and Smoothness

Adopting a multi-oil-circuit partitioned control design, it is equipped with high-precision solenoid valves and pressure regulating valves, which can real-time capture key signals such as engine speed, vehicle speed, and throttle opening, and quickly adjust the pressure and flow of hydraulic oil. Compared with ordinary valve bodies, the shifting response speed is increased by more than 25%, and it can complete gear shifting within 100-200 milliseconds, significantly reducing shifting jitter. At the same time, through linear oil pressure adjustment technology, it optimizes the engagement and disengagement process of the clutch/brake band, avoiding power interruption. Whether it is frequent start-stop in urban congested road conditions or stable driving during high-speed cruising, it can maintain a smooth driving experience.

3. High-Durability Materials and Precision Craftsmanship, Extended Service Life

The core valve plate is made of high-strength die-cast aluminum alloy, which undergoes low-temperature aging treatment and surface nitriding process, with a hardness of over HV750. It can withstand high-frequency oil pressure impacts (maximum pressure resistance of 32MPa) during the operation of the transmission, effectively resisting deformation and cracking of the valve body. The internal spool uses a stainless steel base material with a polytetrafluoroethylene (PTFE) coating, reducing the friction coefficient by 35% and minimizing wear and tear during long-term use. The sealing components are made of hydrogenated nitrile rubber that is oil-resistant and can withstand high and low temperatures (-35℃~140℃), eliminating the risk of transmission oil leakage. Tests show that the service life of this valve body is 45% longer than that of ordinary similar products, making it suitable for long-term use under complex working conditions.
