Pump, Transmission Oil: Operation
| 1- SYSTEM PRESSURE VALVE | 4 - SUMP |
| 2 - PUMP | 5 - PRESSURE PIPE |
| 3 - INTAKE PIPE | 6 - RETURN OF REDUNDANT OIL |
The transmission oil pump is driven by a chain and sprocket. The oil pump has two intake ports and two exhaust ports. The pump draws fluid through a filter and pressurizes the fluid as the pump rotates. After the fluid is pressurized, it exits the pump through two exhaust ports that feed the system pressure valve. The system pressure valve maintains fluid pressure and allows excess pressure to return to the pump. This reduces cavitation and noise.
