09G 09M 09K AWTF60SN Transmission Mechanical Oil Pump Assembly GEN1

The transmission mechanical oil pump is the hydraulic heart of automatic transmissions. Key points:

1. Function – Generates ATF pressure (20-100+ psi) for lubrication, cooling, and clutch/valve body actuation.

2. Types – Gear rotor (gerotor), crescent, or vane pumps; driven by torque converter or input shaft.

3. Failure Modes

   • Wear: Pump gears/vanes degrade from contamination (metal debris).

   • Seal leaks: Causes low pressure (P0841/P0868 codes, delayed shifts).

   • Cavitation: Aerated fluid from clogged filters (whining noise).

4. Critical Specs – Clearance <0.1mm (rotor-to-housing); always prime during installation.
