The **automatic transmission oil pump** is the hydraulic heart of the system:
1. **Pressure Generation** – Creates flow for clutch engagement and shift control.
2. **Lubrication** – Delivers ATF to bearings/gears to prevent wear.
3. **Cooling** – Circulates fluid to manage transmission temperatures.
4. **Torque Converter Feed** – Supplies fluid for power transfer and lockup clutch operation.
Failure = loss of pressure → no shifts → transmission death!
