Technical Details and Performance Attributes

The Wix 51268 transmission filter kit features a robust design tailored for heavy-duty transmissions requiring reliable fluid filtration. The filter media is made from enhanced cellulose, providing a 25-micron filtration rating to capture contaminants effectively while maintaining optimal flow. The filter’s beta ratio of 2/20=7/28 indicates its efficiency in particle retention, ensuring transmission fluid remains clean under high-pressure conditions up to 560 psi burst pressure. The spin-on design with a 1 1/8-16 thread size allows for straightforward replacement in compatible transmission systems. With a height of 5.218 inches and an outer diameter of 3.691 inches, this filter fits specific heavy-duty vehicle models requiring these dimensions.

Compatible Vehicles and Applications

This transmission filter kit is compatible with a range of heavy-duty trucks and commercial vehicles that require a spin-on transmission filter with the specified dimensions and flow characteristics. It is commonly used in transmissions where a high flow rate of 18-20 gpm is necessary to maintain proper lubrication and cooling. The Wix 51268 is suitable for vehicles that demand a Ha class, heavy-duty duty type filter without an anti-drain back valve or bypass relief valve.

• Helps prevent transmission fluid contamination and wear
• Reduces risk of transmission overheating due to clogged filters
• Maintains consistent hydraulic pressure within transmission systems
• Protects transmission components from premature failure
• Supports smooth shifting and overall transmission performance

Installation Notes and Tips

When installing the Wix 51268 transmission filter kit, ensure the transmission fluid is drained and the system is depressurized before removal of the old filter. The spin-on design simplifies installation; apply a light coat of clean transmission fluid to the gasket before threading the filter onto the housing. Tighten the filter according to manufacturer torque specifications to avoid leaks. After installation, refill the transmission with the recommended fluid and check for leaks during operation.

Quality Assurance and Warranty

Wix filters are manufactured to meet stringent quality standards, ensuring reliable filtration performance in heavy-duty applications. The 51268 transmission filter kit undergoes rigorous testing for burst pressure and flow rate to maintain durability under demanding conditions. While specific warranty details are not provided, Wix products typically come with manufacturer-backed quality assurance to support long-term vehicle maintenance needs.
