The OG vs. The Powershift: Difference Between Ford's Auto Transmissions

What is the new Ford Powershift?
Comprising of a six-speed dual-clutch, Powershift is the newest addition to the Ford auto transmission series. Built by Getrag, the Ford Powershift has an improved fuel system. The efficiency of this Powershift is said to be almost ten percent higher than the original automatic transmission.

A dual-clutch transmission works similarly to two classic manual transmissions, each with its own clutch, shifting in tandem and alternately. The Ford gearbox has two clutches, one for first, third, and fifth gears and the other for second, fourth, sixth, and reverse gears. The 2-4-6-R clutch is disengaged as the first gear is engaged, and the second gear gears are engaged. The 1-3-5 clutch is disengaged, and the 2-4-6-R clutch is engaged at the right time—the opposing side changes from first to the third while in second gear. Dry clutches and electric motor/solenoid actuation were employed in some PowerShift transmissions, including the 6DCT250 DPS6 version used in the Ford Fiesta and Ford Focus.

How does the Original Automatic Transmission work?
In the original Ford auto transmission system, the sensors are used to estimate the gear shifts, which are changed through the use of the internal pressure of the oil. To shift gears, an automatic transmission must be briefly removed from the engine, which is controlled by the torque converter lock-up. The varying speeds of an automatic gearbox are achieved by creating different gear ratios. The torque converter uses a mechanism known as "fluid coupling" to transfer power from the engine to the transmission.

What is the Difference between the Powershift and the Original Ford Auto Transmission?

A traditional automatic gearbox consists of a torque converter and a series of planetary gears that are hydraulically driven. The clutch engagement and disengagement, as well as the coupling and decoupling of the gears, are all controlled by hydraulic fluid under pressure. Pressure changes in the hydraulic system as the car accelerates, forcing the transmission to shift upward through all gears in the system. As the car slows, the same pressure changes drive downward shifting.

A dual-clutch mechanism is used in the PowerShift Ford auto transmission; this innovative gearbox selects the next gear for you, so you don't lose power when changing gears. Gears one, three, and five are handled by the first clutch, while gears two, four, and six are handled by the second clutch. Even if the second-gear cogs are engaged, the second clutch is disengaged when the car is in first gear.
