010-398-421A VW & Audi Transmission Gasket Kit - Rabbit, Jetta, Golf

Transmission Gasket Kit – 010-398-421A

Protect your drivetrain and maintain proper fluid levels with the 010-398-421A Transmission Gasket Kit. This comprehensive sealing set is designed for a wide range of water-cooled Volkswagen and Audi manual and automatic transaxles. Unlike the early air-cooled kits, this set is engineered to handle the higher operating temperatures and pressures of the front-wheel-drive and Vanagon platforms. It provides the essential paper gaskets, rubber O-rings, and seals required to refresh a leaking gearbox or complete a full transmission overhaul.

Leaks in these transaxles can lead to catastrophic internal failure if fluid levels drop too low. This kit is manufactured from high-density, oil-resistant materials that provide a reliable barrier against seepage at the main case joins, nose cones, and differential covers. By using precision-cut gaskets that match OEM specifications, you ensure a perfect fit that prevents environmental contaminants from entering your transmission.

Installation & Maintenance Tips

• Clean Surface Finish: Use a gasket scraper and brake cleaner to remove every trace of old gasket material. A clean, dry surface is the only way to ensure the new kit seals properly.

• Check for Warped Pans: On automatic models, ensure the transmission pan rail is perfectly flat. If it was over-tightened previously, the metal can "dimple," leading to leaks even with a new gasket.

• Torque to Spec: Always use a torque wrench to tighten case bolts in a star pattern. Over-tightening can crush the paper gaskets and actually cause them to fail prematurely.

• Verify Sealant Usage: Refer to your factory service manual to see if a specific sealant (like RTV or Anaerobic sealer) is required in conjunction with these gaskets at the "T-joints" where the case halves meet.
