![]() ![]() SSB is a Normally High (NH) solenoid which operates the Direct Clutch for third, fifth and reverse gears.SSA is a Normally Low (NL) solenoid which operates the Forward Clutch for first through fourth gears.Each of the seven solenoids mounted on the rear of the valve body will have a band number on the solenoid to indicate its calibration. With SSB, SSE and the LPC Solenoids being normally high, fifth gear with maximum line pressure is achieved hydraulically when current is removed from the transmission.Īn interesting departure from its 5R110W predecessor is the use of calibrated solenoids. This leaves reverse and fifth gear as the only available gears and TCC will be unlocked. If an electronic, hydraulic or mechanical transmission malfunction occurs, the PCM or TCM will turn off any current to the transmission. ![]() The transmission system is also capable of Tow Haul Mode which will provide all six speeds at higher shift points and also has manual shift capability. When the TCM/PCM detects a fault, Failure Mode Effect Management (FMEM) will be initiated and the transmission will enter fifth and reverse gear limp mode. 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. This is one beefy transmission weighing in at around 350 pounds using the Lepelletier gear-train. These vehicles are available in both 2WD and 4WD configurations along with a Power Take-Off option. ![]() Introduced at the start of production for the 2011 model year, this newly designed full time six-speed transmission found its way into the F250 to F550 Super Duty truck models equipped with the 6.2L Gas Flex Fuel engine or the 6.7 Turbo Diesel engine. This transmission is also referred to as the Torqshift® 6. A recent transmission by Ford to hit the streets is an upscale version of their 5R110W transmission called the 6R140W. ![]()
