Product Details

National has supplied sealing solutions for more than 75 years, and this torque converter seal reflects that focus on transmission sealing accuracy. The 710442 is part of the 710400 series and is engineered around metric dimensions for a proper fit in the specified Jatco transmission housings. If you are servicing a Nissan Sentra with a Jatco RE4F03B transmission or a Volkswagen Jetta with a Jatco JF506E-W transmission, this seal is the type of component used to restore the sealing interface at the torque converter area.

This part cross-references SKF 16536 for the same application.

What It Helps Address

• Transmission fluid leakage at the torque converter seal area
• Sealing wear from age, heat, and fluid exposure
• Improper sealing caused by a worn or hardened original seal
• Service repairs on Jatco-equipped Nissan, Mazda, Volkswagen, Jaguar, Land Rover, and INFINITI vehicles

Installation Notes and Tips

• Verify the transmission code before ordering; fitment depends on the Jatco unit listed for each vehicle.
• Inspect the housing bore and shaft surface for scoring, corrosion, or wear before installation.
• Clean the sealing surfaces thoroughly so the lip can seat evenly.
• Use the exact metric dimensions to confirm the seal matches the application.
• For fitment reference, this seal is used on vehicles such as 2007-2012 Nissan Versa, 2001-2006 Nissan Sentra, 2002-2008 Jaguar X-Type, 2002-2005 Land Rover Freelander, 2002-2006 Mazda MPV, 2003-2004 Mazda 6, 2002-2005 Volkswagen Jetta, and 2003-2006 Volkswagen Golf with the specified transmissions.
