The Beck/Arnley 044-0398 Auto Transmission Filter Kit is a complete OE-fit replacement kit that includes the transmission filter plus the gaskets and O-rings needed for a correct installation.

If you service an automatic transmission, the filter kit is a targeted maintenance item that helps keep fluid clean and the valve body protected. Beck/Arnley engineers this kit to meet foreign nameplate OE specifications for form, fit and function, and supplies the sealing components required for a correct assembly. The package is designed so you can replace the filter and seals in one job without hunting for additional parts.

What components come in the 044-0398 kit and why do they matter?

This kit bundles the transmission filter with the necessary sealing hardware, so you don’t need to source gaskets or O-rings separately. Proper seals ensure reliable fluid containment and help maintain correct hydraulic pressures inside the transmission.

• Replacement transmission filter sized to match OE fitment
• O-rings and/or gaskets required for a complete installation
• Premium molded rubber pan gasket included when applicable
• Application-specific parts to match vehicle requirements

How does the Beck/Arnley filter kit meet vehicle manufacturer standards?

Beck/Arnley parts are made to mirror the shape, mounting points, and filtration performance of the original equipment part. Their quality control and global sourcing network focus on supplying components that install and operate like the factory-installed items.

• Form, fit and function engineered to OE tolerances
• Sealing parts matched to the filter for proper assembly
• Manufactured and inspected to meet nameplate requirements

When should I replace the transmission filter and seals?

Replace the transmission filter and seals according to your vehicle manufacturer’s maintenance schedule or whenever you perform a fluid change and notice contamination. Installing a fresh filter and new gaskets during service reduces the risk of leaks and helps preserve transmission hydraulic performance.

• Follow vehicle OEM interval or during fluid change
• Replace when contamination, wear, or leaks are detected
• Use recommended ATF specified for your transmission

What should I know before installing this kit?

Confirm the kit’s application against your vehicle using the Beck/Arnley catalog or fitment guide so the included components are correct for your transmission. Use the ATF specified for your transmission and torque fasteners to the manufacturer’s recommended values to avoid leaks or damage.

• Verify vehicle application in the Beck/Arnley catalog
• Use the specific ATF formulated for your transmission
• Clean mating surfaces and torque bolts to OEM specs
