The hydraulic control system of the 4F27E has six electronically controlled solenoids for shift feel (through line pressure control), shift scheduling (through shift valve position control) and TCC (torque converter clutch) apply, controlled by pulse-width modulation (PWM).
The hydraulic motor is the rotary counterpart of the hydraulic cylinder as a linear actuator. Most broadly, the category of devices called hydraulic motors has sometimes included those that run on hydropower (namely, water engines and water motors) but in today's terminology the name usually refers more specifically to motors that use hydraulic ...
In a series hydraulic hybrid vehicle, the pump/motor directly connects to the driveshaft, [5] or the in-wheel motors provide driving torque directly to the wheel. The internal combustion engine is only connected to a pump, and is set to operate in its most efficient power range to maintain the optimal hydraulic pressure in the accumulator. [3]
The maximum torque capacity is 330 N⋅m (243 lb⋅ft). The 4HP 22 was produced for vehicles with rear wheel drive or 4X4 layout. Introduced in 1980, it was produced through 2003, and has been used in a variety of cars from BMW, General Motors, Jaguar, Land Rover, Maserati, Peugeot, Porsche, and Volvo.

The Hyper Pak consisted of a very-long-ram intake manifold meant to accept an AFB 4-barrel Carter Carburetor, the AFB carburetor itself and an appropriate air cleaner, dual (front-3 and rear-3) cast-iron exhaust headers, a large-diameter exhaust Y-pipe to connect to these dual cast-iron headers, a larger muffler, a 276°-duration camshaft with ...
Cutaway side-view diagram of an axial piston pump 3-D rendering of an axial piston pump with the parts labeled Animation of an axial piston pump in operation. An axial piston pump has a number of pistons (usually an odd number) arranged in a circular array within a housing which is commonly referred to as a cylinder block, rotor or barrel.
At stall, the torque converter can produce maximum torque multiplication if sufficient input power is applied (the resulting multiplication is called the stall ratio). The stall phase actually lasts for a brief period when the load (e.g., vehicle) initially starts to move, as there will be a very large difference between pump and turbine speed.
