Restore Smooth Shifting with Our ZF Transmission Main Valve Body Seal

If your BMW is experiencing delayed or inconsistent shifting, a worn valve body seal could be the root cause. This high-quality replacement seal is designed specifically for ZF 6-speed automatic transmissions, helping to restore proper hydraulic pressure and smooth transmission performance—without needing a full rebuild kit.

Key Benefits:

• Improves Shift Quality & Response: Replaces your worn or leaking main seal to eliminate sluggish gear changes.
• Restores Internal Fluid Pressure: Helps maintain proper hydraulic flow by sealing critical valve body passages.
• Prevents Long-Term Damage: Stops minor leaks before they lead to major transmission issues.
• Cost-Effective Fix: Ideal for targeted repairs when a full kit isn’t necessary.

Fitment: Compatible with BMW models equipped with ZF 6HP26, 6HP28 and 6HP32 transmissions such as:

• 3 Series — E90, E91, E92, E93: 335d (M57 diesel; confirmed 6HP26)
• 5 Series — E60, E61: 545i, 550i (N62 V8), 530d, 535d (diesel)
• 6 Series — E63, E64: 645Ci, 650i (N62 V8), 635d (diesel)
• 7 Series — E65, E66: 745i/745Li, 750i/750Li (6HP26/28), 760i/760Li (6HP32 V12)
• X5 — E70: xDrive35d (diesel), 4.8i (N62 V8), X5 M (S63; 6HP28 “M Sport” application)
• X6 — E71: X6 M (S63; 6HP28 “M Sport” application)

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

Important Note: This is a high-quality aftermarket part, fully compatible with ZF transmissions, but not an official ZF product. Always note that:

• Many E9X gasoline cars (328i/330i/335i) use 6HP19/6HP21, not 26/28. This seal is not for those unless you confirm the trans code is 6HP26/28.
• Most F- and G-chassis BMWs use ZF 8HP (or DCT on some M cars). Not compatible.
• Always match by VIN or transmission tag (look for GA6HP26Z / GA6HP28Z / GA6HP32Z). If it’s GA6HP19Z / GA6HP21Z or 8HPxx, don’t list it.

Please refer to the “Fitment” section in the product description for compatibility details.
