01M 398 001 – GASKET SET

Description

The 01M 398 001 gasket set is a complete reseal kit for compatible Volkswagen and Audi four-speed automatic transmissions. This maintenance kit provides the necessary gaskets and seals required to address common external leaks and maintain hydraulic integrity. Each component is manufactured to OE-quality specifications to ensure a reliable fit and durable performance under high-temperature conditions.

Resealing the transmission housing and pan is essential for maintaining proper fluid volume and hydraulic pressure. This direct-replacement set helps prevent fluid loss, supporting consistent shift quality and protecting internal transmission components from damage caused by low lubrication levels.

Why the 01M 398 001 Gasket Set Matters

Automatic transmissions depend on a pressurized, sealed environment to command hydraulic gear changes. When a gasket or seal fails, the resulting fluid loss can lead to erratic shifting, increased internal friction, and accelerated wear on clutches and bushings.

Installing a high-quality 01M 398 001 gasket set during maintenance or repair ensures that all primary sealing points are addressed simultaneously. By maintaining a sealed system, you preserve the precise hydraulic control necessary for smooth automatic operation and extend the service life of your vehicle’s drivetrain.

Signs Your Gasket Set Needs Replacing

Inspect the transmission housing and surrounding components if you experience:

• Visible red or brown fluid spots on the driveway or garage floor.

• Wet residue or heavy fluid buildup on the transmission pan or housing seams.

• Low transmission fluid levels during routine checking.

• Sluggish or “slipping” gear engagement caused by pressure loss.

• Difficulty maintaining correct fluid levels after a top-off.

• Burning fluid odor from residue contacting hot exhaust or engine components.

Always confirm the source of a leak, as fluid can migrate from steering components, engine seals, or cooling lines.
