BMW F32/F33/F36 Upgraded Billet Aluminum DCT Transmission Pan – 435i, 440i Models with N55 / B58 3.0L | Refined Cooling, Strength & OEM+ Reliability Upgrade

Experience the next level of performance and reliability with the BAVMODS® Billet Aluminum DCT Transmission Pan, engineered for the BMW F32/F33/F36 4 Series including 435i and 440i models.

BMW’s dual-clutch transmission delivers razor-sharp shifts and lightning-fast response — but the stock composite transmission pan is its weak link. Over time, repeated heat cycles cause the factory plastic pan to warp, leading to slow fluid seepage, inconsistent internal pressure, and premature wear of DCT clutches and seals.

The BAVMODS® Billet Aluminum Upgrade eliminates that issue entirely. Precision-machined for perfect fitment, it improves heat dissipation, enhances rigidity, and guarantees long-term sealing integrity. The result is a transmission that runs cooler, shifts smoother, and performs consistently whether you’re cruising or carving backroads.

Ideal for enthusiasts who want a true OEM+ upgrade, this transmission pan complements the refined character of the F3X 4 Series while delivering the reliability and precision BMW’s DCT deserves.

Key Features & Benefits

• Rigid Billet Aluminum Construction – Prevents deformation under heat and pressure, unlike OEM plastic.
• Enhanced Cooling Efficiency – Optimized fin design improves heat transfer for stable DCT temperatures.
• Consistent Fluid Dynamics – Maintains proper fluid circulation and pressure under aggressive driving.
• Precision Machined Seal Surface – Ensures a leak-free, long-lasting fitment.
• OEM+ Fit & Finish – Direct bolt-on replacement using factory bolts, gasket, and filter.
• Built for Longevity – Designed for high-performance driving, tuned setups, and daily comfort alike.
• Performance You Can Feel

With the BAVMODS® Billet Aluminum DCT Pan, you’ll notice smoother engagement, crisper shifts, and lower transmission temperatures. The additional structural integrity reduces case flex during hard acceleration, translating to more consistent shift logic and improved clutch life.

It’s the perfect balance of engineering and elegance — refined enough for daily driving, yet strong enough for spirited performance.

Why It Matters

Your DCT transmission is a masterpiece of BMW engineering — but it’s only as strong as its foundation. The BAVMODS® Billet Aluminum DCT Transmission Pan upgrades that foundation with true performance-grade precision, ensuring your transmission operates cooler, cleaner, and stronger for years to come.

For 4 Series owners seeking OEM+ reliability and long-term durability, this upgrade is a must-have — built not just for performance, but for confidence.
