The **6F35 (2.0T) torque converter assembly** is a critical component in Ford/Lincoln transverse applications, designed for durability and smooth power transfer. Key features:  

1. **Lockup Clutch** – Enhances fuel efficiency by mechanically coupling the engine/transmission at cruising speeds.  

2. **High-Capacity Design** – Handles 2.0L EcoBoost torque (~350Nm) with reinforced impeller/turbine.  

3. **Dual-Damper System** – Reduces torsional vibrations for refined operation.  

4. **Sealed Fluid Circuit** – Optimized for Mercon LV fluid, minimizing slippage and heat buildup.  

Common issues include premature lockup shudder (fixed via fluid flush/TCM updates) and seal wear leading to contamination. Overall, robust but requires strict maintenance.
