Abstract: A transmission assembly for a machine is disclosed. The transmission assembly may have a clutch pack, a first pressure chamber, and a second pressure chamber. The transmission assembly may also have a first piston configured to push against the clutch pack when pressurized fluid is directed into the first pressure chamber, and a second piston configured to push against the first piston when pressurized fluid is directed into the first pressure chamber and inhibited from pushing against the first piston when pressurized fluid is directed into the second pressure chamber.

Abstract: The temperature of a stationary machine component is controlled by transferring heat generated by a torque converter under restricted conditions to the component. The machine, such as a petroleum drilling or well service machine, includes a circulating fluid system configured to transfer heat from the torque converter to the remotely positioned machine component. Heat generated by the torque converter under the restricted condition is transferred through the circulating fluid system to the remote component, such as the machine power source, to control the temperature thereof.

Abstract: A method of initially operating an internal combustion engine including operating the engine in a start-up mode is provided. The start-up mode includes injecting at least two fuel pre-shots wherein a first of the fuel pre-shots is smaller in quantity than a last of the fuel pre-shots. An engine is provided including an electronic controller with a computer readable medium having a control algorithm recorded thereon, the control algorithm including means for commanding injection of a main fuel shot and at least two fuel pre-shots wherein a first of the fuel pre-shots is smaller in quantity than a last of the fuel pre-shots.
