Automatic Transmission Output Shaft Seal - Ford (JM5Z-1S177-A)

The Automatic Transmission Output Shaft Seal – Ford (JM5Z-1S177-A) is a Genuine OEM sealing component engineered to protect your transmission by preventing fluid leaks at the output shaft. Manufactured by Ford to precise factory specifications, this seal delivers the exact fit, durability, and long-term reliability required for proper drivetrain operation. Its high-quality rubber compound and metal-reinforced structure are designed to withstand heat, pressure, and constant rotational forces.

This OEM output shaft seal fits directly into the transmission housing, ensuring effective sealing between the transmission and driveshaft. Professional mechanics trust Genuine Ford seals because they ensure consistent performance and prevent issues caused by poorly fitting aftermarket options. DIY mechanics will also find it straightforward to install, thanks to its exact dimensions and compatibility with the factory shaft and housing.

The JM5Z-1S177-A plays a crucial role in maintaining correct transmission fluid levels, supporting smooth shifting and proper lubrication. A failing output shaft seal can lead to visible leaks, slipping, overheating, and premature transmission wear. Replacing it with a Ford-engineered seal restores factory-level performance and protects the system from contamination and fluid loss.

Engineered to withstand demanding drivetrain conditions, this seal resists cracking, hardening, and deformation caused by temperature cycles and chemical exposure. Its precision-engineered sealing lip maintains a consistent, leak-free barrier throughout its service life.

• Genuine OEM Ford seal engineered for precise transmission fitment

• Heat- and fluid-resistant materials provide long-term sealing performance

• Helps maintain correct transmission fluid levels and smooth shifting

• Direct-fit design simplifies installation for both professionals and DIY users

• Protects transmission components from contamination and premature wear

• Reinforced construction resists cracking, swelling, and high-temperature stress

Choosing the Automatic Transmission Output Shaft Seal – Ford (JM5Z-1S177-A) ensures your drivetrain remains properly sealed, protected, and operating at factory performance standards using a reliable, OEM-quality component.
