National TREMEC 3150 Output Shaft Seal Mustang 96-10

Fluid retention at the transmission output is essential for proper drivetrain operation. This National output shaft seal for 1996-2010 Mustangs helps maintain internal lubrication by sealing the output shaft opening on TREMEC 3150 manual transmissions. It prevents fluid loss while keeping external contaminants from entering the transmission housing.

Features and Benefits:
- Seals output shaft to prevent fluid loss
- Nitrile rubber material resists wear
- Spring-loaded lip maintains seal contact
- Bi-directional design moves fluid away
- Helps block dirt and moisture intrusion

The seal uses a spring-loaded nitrile rubber construction to maintain consistent contact with the shaft surface. A bi-directional helix lip design directs fluid away from the sealing edge, supporting long term sealing performance. This output shaft seal is intended for use during transmission service or replacement to maintain proper operation.
