Product Description
The 46313-4J100 is a shift control solenoid valve engineered for Hyundai Genesis and Kia luxury vehicle platforms, designed as a direct replacement for original equipment components in automatic transmission hydraulic control units. This component receives pulse-width modulation (PWM) signals from the Transmission Control Unit (TCU) to regulate hydraulic pressure for clutch and brake band operation, supporting consistent gear shifting performance. It is supplied for commercial procurement, serving authorized dealership parts departments and luxury vehicle repair facilities.
This solenoid fits Hyundai and Kia vehicles with 6-speed and 8-speed automatic transmission architectures, covering model years 2017 to 2025. Compatible models include Hyundai Genesis DH/JK/JK1, Genesis G80, Genesis G90, Kia Stinger CK, and Kia K900. It mounts inside the transmission valve body, within the hydraulic control unit beneath the oil pan.

The solenoid receives PWM control signals from the TCU to adjust hydraulic pressure delivered to each clutch pack and brake band. Precise pressure regulation supports smooth gear transitions during acceleration and deceleration. Optimized magnetic circuit design delivers armature response within 15 milliseconds, allowing the transmission to execute sequential downshifts during deceleration without delay. The coil uses high-purity oxygen-free copper wire to limit internal resistance and heat buildup during extended operation.
All sealing components use Viton-grade fluorine rubber O-rings, which maintain elasticity and sealing performance after prolonged immersion in automatic transmission fluid at temperatures up to 120°C. The solenoid body is molded from PA66-GF30 glass fiber reinforced nylon, which resists swelling, deformation, and chemical degradation from aged ATF additives. Each unit completes 50,000-cycle endurance testing before leaving the production facility to verify consistent performance across its service lifespan.
This unit is manufactured with identical electrical connector pinout and valve body bore dimensions to the original component. No TCU reprogramming or recalibration is required after replacement. Installation is completed by removing the valve body cover plate, extracting the faulty solenoid, and fitting the new unit. Adaptation value reset via diagnostic scanner is recommended after installation to restore factory shifting characteristics.
Worn or faulty solenoids may trigger observable transmission symptoms, with standard diagnosis and resolution paths as follows.
Harsh or delayed shifting: Typically caused by spool valve sticking from contaminated ATF, internal coil circuit damage, or seal leakage. Diagnosis includes scanning for DTC codes P0741-P0774, monitoring actual vs. commanded gear ratio, and measuring solenoid resistance against the 5.0-6.2 ohm specification.
Transmission limp mode: May occur from complete solenoid failure, wiring harness damage, or TCU protection mode activation. Inspection of the transmission wiring connector and replacement of faulty units are standard resolutions.
RPM flare during shifting: Often linked to slow solenoid response from internal wear or clogged inlet screens. Resolution includes replacing affected solenoids, cleaning inlet filters, and flushing transmission cooler lines.
For commercial procurement clients including parts distributors and repair service operators, flexible order quantities are available with a minimum order quantity starting at 500 units. Two packaging options are provided: genuine-standard Mobis specification packaging, and aftermarket packaging covering neutral packaging and custom brand packaging. All units are produced under IATF16949-certified processes, with consistent specifications across batch orders.
This aftermarket replacement component is manufactured to match original equipment fit, form, and functional specifications, with dimensional and electrical parameters aligned with factory production standards.
Standard automotive hand tools are sufficient for installation. A torque wrench is recommended to tighten fasteners to factory-specified values. Reference to the vehicle’s official service manual is advised for model-specific procedures.
Fitment can be confirmed by cross-referencing the OEM part number 46313-4J100 with your vehicle’s VIN through an authorized dealer, or by matching your vehicle model, year, and transmission type against the provided compatibility list.
