2222402918 2172400000 Transmission Mount for Mercedes Benz S-CLASS C217 W222

2222402918 2172400000 Transmission Mount for Mercedes Benz S-CLASS C217 W222 M157

Product Introduction

The 2222402918 / 2172400000 Transmission Mount is a precision-engineered suspension component specifically designed for the Mercedes-Benz S-Class C217 coupe and W222 sedan, equipped with the high-performance M157 biturbo V8 engine. This mount serves as the critical load-bearing and vibration-damping link between the transmission and the vehicle subframe or crossmember. By securing the drivetrain in its correct alignment while absorbing torsional forces and road-induced vibrations, this OEM-grade replacement part restores original shifting smoothness, reduces drivetrain noise, and prevents excessive movement of the transmission under load.

Product Features

• OEM Direct Fitment: Engineered to replace original part numbers 2222402918 and 2172400000, designed exclusively for Mercedes-Benz S-Class C217 and W222 models with the M157 engine.

• Heavy-Duty Rubber-Metal Construction: Features a durable natural rubber or high-grade elastomer core bonded to a powder-coated steel or aluminum housing, offering excellent vibration isolation and structural strength.

• Hydraulic or Solid Damping Design: Depending on the specific OE configuration, this mount incorporates either hydraulic fluid-filled chambers or solid rubber dampening to effectively minimize drivetrain oscillations and road harshness.

• Corrosion-Resistant Housing: The outer casing is treated with an anti-rust coating to withstand engine bay heat, moisture, and road salt exposure over extended service life.

• Precise Load Capacity: Matched to the torque output and weight characteristics of the M157 twin-turbo V8, providing optimal support without being overly stiff or too soft.

• Integrated Alignment Features: Includes locating pins or offset bolt holes to ensure correct installation position, preventing drivetrain misalignment.

Key Selling Points

• Eliminates Drivetrain Vibrations and Clunking: A worn or collapsed transmission mount allows the drivetrain to shift under acceleration or deceleration, causing clunking noises, vibration in the cabin, and harsh gear changes. Replacing it restores the signature smooth and quiet ride of the Mercedes-Benz S-Class.

• Protects the Transmission and Driveshaft Components: Prevents excessive movement of the transmission, which can lead to misaligned driveshaft angles, premature CV joint wear, or damage to shift linkage and exhaust components.

• Restores Precise Shifting Feel: By keeping the transmission rigidly yet compliantly positioned, this mount ensures consistent engagement and smoother gear transitions, especially under heavy throttle or during low-speed maneuvers.

• Specifically Engineered for High-Torque M157 Engines: Unlike universal mounts, this part is calibrated to handle the substantial twisting forces generated by the AMG-tuned biturbo V8, ensuring long-term durability and performance.

• Cost-Effective OEM Alternative: Delivers factory-level quality and fitment at a competitive price point, making it an ideal solution for both routine drivetrain maintenance and major transmission repairs.

• Simple Bolt-In Replacement: Designed for straightforward installation by professional technicians or experienced DIY enthusiasts with basic tools, reducing labor time and minimizing vehicle downtime.
