The pan body is formed from PA66+GF35 glass-fiber-reinforced nylon, matching the material formulation of original equipment units. This composite material delivers a defined strength-to-weight ratio, exhibits corrosion resistance, and reduces transmission operational noise transmission compared to stamped steel alternatives. Grid-pattern reinforcement ribs are molded into the inner surface to maintain structural rigidity under internal fluid surge forces. Molded-in brass threaded inserts at each bolt hole support repeated torque cycles during installation and maintenance procedures. The unit has a net weight of approximately 1.35 kg, which is 60 percent lighter than stamped-steel transmission pans of equivalent dimensions. The lightweight construction also reduces handling effort during warehouse logistics and on-site installation procedures for service teams.
The mating flange surface is produced with controlled flatness tolerances to support uniform compression of the perimeter gasket. An integrated gasket groove is molded into the sealing surface to hold the compressible gasket in position during assembly. This design supports stable sealing performance across the transmission’s operating temperature range, from -40°C cold start conditions to 130°C peak operating temperatures. The drain plug is positioned at the lowest point of the pan to enable complete fluid drainage during maintenance operations. A neodymium magnet embedded in the drain plug housing captures ferrous wear particles suspended in automatic transmission fluid, including gear tooth and bearing wear fragments.
Each 45280-4G150 oil pan is manufactured to align with Hyundai-Kia Mobis original equipment specifications, with production processes managed under ISO/TS16949 quality management system requirements. Every finished unit undergoes pressure testing and dimensional inspection prior to shipment to verify conformance with stated dimensional and performance specifications. Inspection protocols cover critical dimensions including bolt hole spacing, flange flatness, and overall outer dimensions to ensure interchangeability with original units.
This transmission oil pan is designed for vehicles equipped with the A8LF1 8-speed automatic transmission. Compatible models include:
Hyundai Santa Fe (2015-2021)
Kia Sedona / Carnival (2015-2021)
Kia Sorento UM (2015-2021) Business buyers may verify fitment by cross-referencing the OEM part number 45280-4G150 with official vehicle part catalogs or VIN lookup systems.
This aftermarket replacement part is engineered to meet original equipment fit, form, and function specifications. Production follows ISO/TS16949 quality system requirements, with each unit undergoing standardized testing before release.
Compatibility can be confirmed by cross-referencing the OEM part number 45280-4G150 with your vehicle’s official parts catalog or VIN-based part lookup tool. The part is intended exclusively for vehicles with the A8LF1 8-speed automatic transmission.
The minimum order quantity for this transmission oil pan ranges from 500 to 1000 units. Custom packaging configurations are available for bulk purchases to align with different business operations needs.
Available packaging options include genuine (MOBIS) standard packaging, neutral aftermarket packaging, and custom branded packaging, to suit different distribution and operational requirements.
It is recommended to replace associated wear items such as pan gaskets and transmission filters during oil pan installation. This approach supports consistent transmission performance and reduces repeated maintenance labor input.
