Restore Smooth Shifting with Our ZF Transmission Valve Body Seal Kit

Breathe new life into your transmission with our comprehensive 6-piece valve body seal kit — specifically designed for ZF 6-speed automatic transmissions. If you’re experiencing delayed or sluggish shifts, worn internal seals are often the culprit. This kit helps restore proper fluid pressure, improve shift response, and extend transmission lifespan, giving you back the performance your BMW was built for.

Key Benefits:

• Improves Shift Quality & Transmission Response: Eliminate sluggish gear changes with fresh seals that restore hydraulic integrity.
• Restores Internal Fluid Pressure: Prevents leaks and pressure drops that lead to poor performance.
• Increases Transmission Longevity: Avoid long-term damage caused by degraded or leaking seals.
• Complete 6-Piece Kit: Includes all essential seals to rebuild the valve body area for optimal performance.

Fitment: Compatible with BMW vehicles equipped with ZF 6HP19, 6HP21, 6HP26, or 6HP28 transmissions.

Use a VIN decoder or scan tool to confirm your exact transmission model before purchasing.

Important Notes: This is a high-quality aftermarket kit, not an official ZF product, but fully compatible with the ZF transmission line.

Kit includes:

• 1 Mechatronic sleeve
• 1 Valve body-to-case seal
• 4 Valve body sleeve gaskets

Selecting the 6HP19/21 kit provides the rigid-style sleeve stems, while choosing the 6HP26/28 kit includes the smooth seal versions.

These ZF transmissions were used in a wide range of vehicles, including BMW, Jaguar, Land Rover, and more — please verify your transmission model before purchasing.
