LEMFOERDER Control 36505 01 – Automatic Transmission Mounting

The LEMFOERDER Control 36505 01 is a precision‑engineered mounting designed to secure the automatic transmission in high‑performance vehicles. Crafted from advanced alloy materials, it delivers exceptional rigidity while maintaining lightweight characteristics essential for modern automotive dynamics.

Key Functional Features

• High‑Strength Construction: Made from a proprietary steel blend that resists fatigue and corrosion, ensuring long‑term reliability under extreme operating conditions.
• Optimized Load Distribution: The mounting’s geometry spreads torque evenly across the transmission housing, reducing stress concentrations and extending component life.
• Precision Fitment: Designed to match the exact dimensions of the automatic transmission used in Mercedes‑Benz S‑Class (W221) and C216 models, guaranteeing a snug fit without the need for extensive modifications.
• Ease of Installation: Features pre‑drilled holes and standardized fastener positions that align with factory mounting points, allowing technicians to install or replace the unit in minimal time.
• Thermal Stability: The alloy’s low coefficient of thermal expansion maintains dimensional stability across a wide temperature range, preventing loosening due to heat cycles.

Compatibility Overview

The Control 36505 01 is specifically engineered for the following vehicle platforms:

• Mercedes‑Benz S‑Class (W221) – rear automatic transmission mounting
• Mercedes‑Benz C216 – rear automatic transmission mounting
• Other Mercedes models with identical transmission housing geometry, such as the V221 and W221 series.

Its design aligns with the factory specifications for these models, ensuring that all mechanical interfaces—bolt patterns, flange dimensions, and load paths—are fully compatible.

Material Composition & Manufacturing Process

The mounting is fabricated from a high‑strength alloy steel (commonly 20MnMoV5 or equivalent), which undergoes the following steps:

1. Casting: The raw material is cast into a near‑final shape, reducing machining time.
2. Heat Treatment: Austenitizing followed by quenching and tempering achieves the desired hardness (approximately 350–380 HB) while preserving toughness.
3. Surface Finishing: The component is polished to a fine finish, then coated with a corrosion‑resistant layer (e.g., zinc plating or anodized coating).
4. Quality Inspection: Dimensional checks, hardness testing, and non‑destructive evaluation confirm adherence to stringent automotive standards.

Installation Guidelines

1. Preparation: Clean the mounting surface and ensure all fastener holes are free of debris.
2. Alignment: Position the Control 36505 01 so that its mounting flange aligns precisely with the transmission housing.
3. Tightening Sequence: Use a torque wrench to tighten bolts in a star pattern, following the manufacturer’s recommended torque values (typically 80–100 Nm).
4. Verification: After installation, perform a vibration test to confirm that the mounting remains secure under operational loads.

Performance Benefits

• Reduced Vibration: The rigid construction dampens transmission‑induced vibrations, improving cabin comfort and reducing wear on adjacent components.
• Enhanced Durability: By maintaining a stable mounting interface, the component helps prevent premature failure of bearings and seals within the transmission.
• Improved Handling: A secure transmission mount contributes to better weight distribution and vehicle dynamics, especially in high‑performance driving scenarios.

Maintenance & Inspection Tips

Although the Control 36505 01 is designed for long‑term use, periodic checks are recommended:

• Inspect bolts for tightness every 10,000 miles or after any significant impact event.
• Check for signs of corrosion or wear on the mounting surface; clean and reapply protective coating if necessary.
• Verify that the mounting does not interfere with adjacent components such as exhaust systems or suspension arms.

Conclusion

The LEMFOERDER Control 36505 01 represents a pinnacle of engineering for automatic transmission mounting solutions. Its combination of material excellence, precise fitment, and robust performance makes it an indispensable component for maintaining the integrity and longevity of high‑performance vehicles such as the Mercedes‑Benz S‑Class and C216 series.
