Introducing Ford's Torqshift 6 Transmission

摘要

A recent transmission by Ford to hit the streets is an upscale version of their 5R110W transmission called the 6R140W. This transmission is also referred to as the Torqshift® 6 (Figure 1). Introduced at the start of 2011 MY production, this newly designed, full-time, six-speed transmission found its way into the F250 to F550 Super Duty truck models with the 6.2L Gas Flex Fuel engine or the 6.7 Turbo Diesel engine. These vehicles are available in both 2WD and 4WD configurations along with a Power Take-Off option. This is one beefy transmission weighing in at around 350 pounds using the Lepelletier gear-train. The 6R140W is electronically controlled by seven pulse width modulated (PWM) solenoids and uses an external Transmission Control Module (TCM) in diesel powered applications or an external Powertrain Control Module (PCM) for gasoline powered applications.
