FORD 5R110W TorqShift

The new Ford 5R110W, referred to by Ford Motor Company as the "TorqShift" transmission, is a redesign of
the 4R100 transmission with some previous strategy applied. This unit was introduced in model year 2003 in
the F Series Trucks and the Excursion vehicles that are equipped with the new 6.0L diesel engine. The
"TorqShift" (5R110W) is a 5 speed, rear wheel drive unit that actually has six forward speeds available,
depending on hot or cold mode operation. The gear ratio for 1st gear was lowered from 2.71 to 3.09. For 2nd
gear the overdrive clutch is applied to provide a ratio of 2.20. 3rd gear provides a ratio of 1.54, which is the same
ratio as the previous second gear. All sound familiar? When in cold mode operation, below -15°C (5°F),
determined by the TFT sensor, the overdrive clutch is engaged in 3rd gear to provide a ratio of 1.09 for 4th gear,
and the transmission will shift directly into 6th gear (overdrive), which is a ratio of 0.71. In cold mode the
transmission shifts 1st gear, 2nd gear, 3rd gear, 4th gear, 6th gear. When in hot mode the transmission will shift
1st gear, 2nd gear, 3rd gear, 5th gear (ratio 1.00), 6th gear. Either way it is still a five speed unit with six forward
gear ratios available, depending on cold mode or hot mode of operation.
