Product Description
The 46313-2F400 is a pressure control solenoid valve built for 6-speed automatic transmissions, acting as a core hydraulic control component on the transmission valve body. It receives electronic signals from the Transmission Control Unit (TCU) to adjust oil pressure in real time, regulating the engagement and disengagement of overdrive and underdrive clutches to support smooth gear shifting. Designed as a direct replacement for corresponding original parts in Hyundai and Kia vehicles, it supports maintenance and replacement operations for automotive repair and parts distribution businesses.

The valve spool is manufactured via a single-step powder metallurgy molding process, achieving tight tolerance matching. This design maintains stable oil flow control over extended operation periods, reducing risks of valve sticking and shift delay. The dimensions align with original equipment specifications, enabling direct plug-and-play replacement without modification or additional machining.
The internal electromagnetic coil is wound with heat-resistant enameled copper wire, withstanding continuous exposure to transmission oil temperatures up to 150°C. The outer shell features an anti-oxidation coating, which resists oil corrosion and rust formation, supporting long-term operation in the high-temperature, oil-immersed environment inside the gearbox.
The green plastic connector is fitted with an integrated rubber sealing ring, which prevents transmission fluid leakage and electrical short circuits. The dust and oil-resistant structure reduces ingress of debris, extending service life compared with standard remanufactured solenoid valves.
This solenoid valve fits Hyundai and Kia vehicles produced between 2016 and 2025, specifically those equipped with the A6GF1 (Hyundai designation) / U6EA (Kia designation) 6-speed automatic transmission. Core compatible models include Hyundai Elantra, Tucson, Sonata Hybrid, Santa Fe Hybrid and Kona, as well as Kia Forte, Soul, Sportage and Sorento, covering both gasoline and hybrid powertrain variants. The part can be used as a replacement for cross reference number 46313-3B600 in applicable vehicles. Buyers are advised to verify the original part number and transmission model before procurement to ensure fitment.
Each unit undergoes three standardized tests before delivery: hydraulic pressure test, electromagnetic conduction test, and aging cycle test. The entire production process complies with ISO automotive parts manufacturing standards, to ensure consistent performance across batch orders.
The minimum order quantity starts at 500 units, with support for batch procurement ranging from 500 to 1000 units. All units are covered by a 12-month quality warranty. Packaging options include genuine standard packaging, neutral packaging, and branded custom packaging, which can be selected based on commercial procurement and inventory requirements.
Contaminated or burnt transmission fluid containing metal debris can clog the fine oil bores of the new solenoid, and a worn old filter will fail to capture impurities. To resolve this, flush the entire transmission hydraulic system with new ATF fluid, replace the transmission filter and oil pan gasket, and clean valve body oil channels to remove metal particles before reinstallation.
After solenoid replacement, the Transmission Control Module (TCM) may lose its original shift pressure calibration and require adaptive learning. Normal driving for 50–100 miles under mixed speed conditions will complete the TCM self-learning process. If issues persist, a professional vehicle scanner can be used to perform a manual TCM reset and shift point relearn.
The standard coil resistance is 5.0–5.6 ohms at 20°C. A reading outside this range may indicate coil damage. For on-vehicle inspection, the solenoid connector pin should receive stable 12V battery voltage with the ignition on and engine off; an audible buzz during actuation indicates normal coil function.
Leakage typically results from reusing a worn original sealing ring, or over-torqued / loose mounting bolts. Always install a new rubber sealing O-ring with each new solenoid, and torque mounting bolts to the standard 8 Nm to avoid valve body cracking. Clean residual fluid and metal shavings from the mounting seat before installation.
