Mercedes-Benz W176 (A-Class) 7G-DCT Automatic Torque Converter | Genuine Replacement

Description

In the 7G-DCT (Dual Clutch Transmission) system found in the W176 A220 CDI, the “torque converter” assembly (often integrated with the dual-clutch housing) is the heart of your drivetrain’s power delivery. If your car is experiencing “shuddering” during acceleration, high RPM slip, or a “clunk” when engaging Drive or Reverse, the internal friction discs or the lock-up clutch assembly may be failing.

Our workshop-vetted original torque converter/dual-clutch assemblies are the professional solution to restore smooth, factory-standard shifting without the exorbitant cost of a dealership transmission replacement.

• Smooth Power Delivery: Restores the refined, seamless gear engagement that the A-Class is famous for.

• Lock-Up Clutch Efficiency: Fixes “slip” issues where engine RPM fluctuates independently of vehicle speed, restoring fuel efficiency and performance.

• Condition: Premium workshop-vetted original component; inspected for seal integrity, spline wear, and internal clutch pack health.

Signs Your Torque Converter/Clutch Assembly is Failing:

• Transmission Shudder: A rhythmic vibration or “shaking” sensation when the car shifts gears or accelerates from a stop.

• High-RPM Slip: You press the accelerator, and the engine RPM jumps up, but the car feels like it isn’t “catching” or moving forward immediately.

• Engagement Delay: A noticeable “lag” or “bump” when shifting between Park, Drive, and Reverse.

• Whining Noise: A faint, high-pitched whine that changes with engine load, often indicating internal hydraulic pressure loss.

Workshop Pro-Tip: The 7G-DCT transmission is incredibly sophisticated. When replacing the torque converter/clutch assembly, it is mandatory to perform a “Clutch Adaptation” using an advanced diagnostic tool. Without this reset, the transmission’s Transmission Control Unit (TCU) will try to apply pressure based on the old worn clutch’s friction points, which will cause your new unit to drive poorly and fail prematurely. Always use high-quality, manufacturer-approved transmission fluid to protect the new components!

Key Features:

• Perfect Compatibility: Designed specifically for the W176 7G-DCT automatic transmission and OM651 engine torque curve.

• Restored Performance: Eliminates slip and drivetrain vibration, returning your A-Class to factory-smooth shifting.

• Quality Assured: Vetted for structural integrity and smooth spline engagement.
