Transmission Oil Pump

E40D 4R100 Automatic Transmission Oil Pump RF-F81P-7B324-AA

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!

6T40 Automatic Transmission Oil Pump Assembly 27 Millimeters

"The 6T40 oil pump is a gear-driven, positive displacement pump critical for hydraulic pressure (maintaining 60-90 PSI in normal operation). Key features: Design: Twin crescent-type gears with aluminum housing, driven directly by the torque converter. Functions: Supplies pressurized fluid for clutch engagement, cooling, and valve body operation. Failure Signs: Whining noise (especially when cold), delayed shifts, or pressure-related DTCs (e.g., P0841). Weak Points: Common

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

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

45RFE 545RFE Automatic Transmission Mechanical Oil Pump For 2012 Jeep Grand Cherokee

Function: Generates hydraulic pressure (90-150 psi) for clutch/band operation and lubrication in Jeep/Dodge RWD applications. Key Features: Gear Type: Crescent pump design with cast aluminum housing (OEM 05015851AB ). Critical Specs: 0.05-0.10mm gear-to-housing clearance; relief valve calibrated to 160 psi. Failure Modes: Crescent Wear: Abrasives score pump face (low pressure → P1762/P2769 codes). Seal Hardening: ATF+4 breakdown causes internal leaks (slow 3-4 shifts). Drive

4L65E Mechanical Oil Pump Assembly 1998 - 2003 300mm

Typical Faults: Crescent Wear Symptom: Low line pressure (P0756/P0776 codes, delayed shifts) Cause: Abrasives score pump face (especially after torque converter failure) Drive Gear Spline Stripping Symptom: No movement in any gear (metal debris in pan) Cause: Torque converter hub wear transfers to pump Pressure Regulator Sticking Symptom: Erratic shifts or harsh engagements Trigger: Varnish buildup from degraded Dexron III Critical Measurements: Rotor Clearance: >0.15mm

4R100 Automatic Transmission Oil Pump RF-F81P-7B324-AA

Typical Faults: Rotor/Gear Wear Symptom: Low line pressure (P0841/P0868 codes, delayed shifts) Cause: Contaminated ATF or metal debris scoring surfaces Seal Failure Symptom: Pressure loss at idle (pump whine) Trigger: Hardened/rolled seals from heat/age Cavitation Damage Symptom: Foamy ATF, erratic shifts Root Cause: Clogged filter or aerated fluid Critical Checks: Clearance: Rotor-to-housing >0.15mm = replace Prime Test: Should generate 20+ psi instantly at crank Debris
