The transmission mechanical oil pump is the hydraulic heart of automatic transmissions. Key points:
Function – Generates ATF pressure (20-100+ psi) for lubrication, cooling, and clutch/valve body actuation.
Types – Gear rotor (gerotor), crescent, or vane pumps; driven by torque converter or input shaft.
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).
Critical Specs – Clearance <0.1mm (rotor-to-housing); always prime during installation.
