Forward Clutch Drum Belt Solid Shaft Of The 4R70E 4R70W And 4R75E Transmission

The **forward clutch drum with solid shaft** in an automatic transmission:

1. **Power Transfer Hub** – Connects input torque to planetary gearsets for forward drive.

2. **Clutch Pack Anchor** – Houses friction plates/steels engaged hydraulically (D/1-2-3 gears).

3. **Direct Mechanical Link** – Solid shaft ensures rigid torque delivery (no flex vs. hollow designs).

4. **Durability Focus** – Resists torsional stress from engine load.

Failure = forward gear loss or shudder!
