The **automatic transmission mechanical oil pump** is crucial for: 1. **Hydraulic Pressure** – Generates flow to engage clutches/bands. 2. **Lubrication** – Protects gears/bearings from wear. 3. **Cooling** – Circulates ATF to dissipate heat. 4. **Torque Converter Operation** – Supplies fluid for power transfer. Powered by the engine (via input shaft), it ensures smooth shifts & longevity. Failure = no pressure = transmission breakdown! ⚙️

Function: Transmits engine torque to the planetary gearset via engaged clutch plates (typically 1st-3rd/4th gears). Key Components: Input Shaft: Hardened steel with precision-ground splines (connects to torque converter) Clutch Drum: Aluminum/steel hybrid with laser-welded piston channel Integrated Piston: High-pressure seals (Vitron or HNBR) for rapid apply Failure Modes: Spline Wear: Causes clutch drag (delayed engagement, P0776 codes) Drum Warpage: Overheating distorts
