The letter F stands for "F"ront-wheel-drive. Although the F28 is only used in 4WD applications, the base transmission still remains a common FWD gearbox. The number 28 stands for the maximum torque capacity in Nm/10. 28 means that, the transmission is capable of transferring 280 N⋅m (210 lb⋅ft) nominal torque to the input shaft.
A manual transmission (MT), also known as manual gearbox, standard transmission (in Canada, the United Kingdom and the United States), or stick shift (in the United States), is a multi-speed motor vehicle transmission system where gear changes require the driver to manually select the gears by operating a gear stick and clutch (which is usually ...
A dog-leg gearbox or dogleg gearbox is a manual transmission shift pattern distinguished by an up-over-up shift between first and second gear. [1] The layout derives its name from a dog's hind leg, with its sharp angles. Dog leg gearboxes were replaced in most mass production vehicles by transmissions with a standard gear layout.
It was a 5 speed transmission with the following specifications: [2] Clutch Diameter 9.0 inches (230 mm) 1st Gear Ratio 3.55:1 2nd Gear Ratio 2.16:1 3rd Gear Ratio 1.48:1 4th Gear Ratio 1.13:1 5th Gear Ratio 0.89:1 Reverse Gear Ratio 3.33:1 Final Drive Ratio 3.55:1. 3.42:1 or 3.72:1 found in 4WD F20's.
For the wide-ratio transmission, the first gear ratio is 4:1 or 4, and in second gear it is 2:1 or 2, so the progression is equal to 4 / 2 = 2 (or 200%). For the close-ratio transmission, first gear has a 4:1 ratio or 4, and second gear has a ratio of 3:1 or 3, so the progression between gears is 4 / 3 , or 133%. Since 133% is ...
By selecting L from stationary, or before an upward gear change into 2nd gear, the transmission will become locked in 1st gear. By selecting L from D2 or D1 while in 2nd gear, the transmission will become locked in 2nd gear or from D2 or D1 when cruising below 55 m.p.h (88 k.p.h.) will effect an immediate downward change and lock in 2nd gear.
A semi-automatic transmission is a multiple-speed transmission where part of its operation is automated (typically the actuation of the clutch), but the driver's input is still required to launch the vehicle from a standstill and to manually change gears.
The Ford unit is a six-speed with one clutch acting on reverse, first, third, and fifth gears, and the other used for second, fourth, sixth gears. As the first gear is engaged, the 2-4-6 clutch is disengaged and the second gear cogs are engaged. At the appropriate time, the R-1-3-5 clutch is disengaged and the 2-4-6 clutch is engaged.
