2. Float shifting - Wikipedia

   en.wikipedia.org/wiki/Float_shifting

   Float shifting can reduce clutch wear because it is used so much less (only for starting from a standstill). Conversely, improper engagement of a gear (when the engine and transmission speeds aren't matched) can cause wear on the synchros and lockouts, and damage the gears by physically grinding them together due to a difference in speed.

3. Ford PowerShift transmission - Wikipedia

   en.wikipedia.org/wiki/Ford_PowerShift_transmission

   This all makes wet clutches better suited for use in DCTs, and thus Ford experienced problems with models of the transmission which used dry clutch packs. Ford has faced class-action lawsuits and fraud investigations in the United States, [ 4 ] Australia [ 5 ] and Canada [ 6 ] over the PowerShift gearbox as being defective and potentially ...

4. Powershifting - Wikipedia

   en.wikipedia.org/wiki/Powershifting

   Powershifting, also known as full-throttle shifting or flat-shifting, is a method of gear shifting used with manual transmissions to reduce the time where the driving wheels are not powered. Unlike during a normal gear change, in a powershift the driver does not let off the accelerator.

   If the transmission control unit senses a critical fault during driving, it will activate an emergency operating mode: Upon hydraulic failures, it will stop shifting gears and permanently retain the currently selected gear; if the failure can be pinpointed to one of the internal hydraulic control valves, the transmission will continue shifting but stop using the affected gear(s).

6. Ultramatic - Wikipedia

   Despite the problems of later versions, the transmission worked beautifully under the use conditions it was designed for. Packard's Gear-Start Ultramatic (1954), Twin Ultramatic (1955), and Ultramatic Drive (1956), struggled to reliably automate the low to high gear shift transition.

7. Automatic transmission - Wikipedia

   en.wikipedia.org/wiki/Automatic_transmission

   This unit was an early semi-automatic transmission, based on the design of a conventional manual transmission, which used a servo-controlled vacuum-operated clutch system, with three different gear shifting modes, at the touch of a button; manual shifting and manual clutch operation (fully manual), manual shifting with automated clutch ...
