• 1 x matched gasket for a reliable pan seal
• Using the gasket with the filter reduces the chance of leaks and helps maintain correct fluid pressure

MK-Morzon subjects every filter kit to factory testing and certifies that the components meet or exceed OEM-level quality. The filter’s materials and construction are selected for durability and consistent filtration performance under typical driving conditions.

• 100% tested before leaving the factory
• Constructed from durable media and sealing materials for long service life
• Manufactured to meet or surpass OEM specifications for fit and filtration

When should I replace the transmission filter and what benefits will I see?

Replacing the transmission filter during scheduled service or when performing a fluid change helps preserve shift quality and prevents premature wear caused by contaminants. A fresh filter and secure gasket contribute to consistent hydraulic operation and reduced risk of overheating or slipping caused by clogged filtration.

• Recommended during transmission fluid service or if contamination is suspected
• Helps maintain smooth shifting and prolongs transmission life
• Prevents debris from circulating through valves and solenoids
