Product Overview
At the start of production for the 2011 model year Ford Motor Company introduced a newly designed full time six speed 6R140W transmission also known as the Torqshift® 6, for the F250 to F550 Super Duty truck models equipped with the 6.2L Gas Flex Fuel engine or the 6.7 Turbo Diesel engine. It is available in both 2WD and 4WD configurations and can be Power Take-Off capable. The 6R140W assembled weight is 350 Lbs. and is of the Lepelletier geartrain design consisting of a Simpson planetary gearset, a Ravigneaux gear set, two holding clutches, three drive clutches, a one-way clutch and a torque converter clutch. TCC can be commanded on from first to sixth gear. The 6R140W is electronically controlled by seven pwm solenoids and uses a Transmission Control Module (TCM) in diesel powered applications or a Powertrain Control Module (PCM) for gasoline powered applications. 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 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.
