A direct-shift gearbox (DSG, German: Direktschaltgetriebe [1]) [2] [3] is an electronically controlled, dual-clutch, [2] multiple-shaft, automatic gearbox, in either a transaxle or traditional transmission layout (depending on engine/drive configuration), with automated clutch operation, and with fully-automatic [2] or semi-manual gear selection.
A long shift time is considered anything over 625 milliseconds. [2]The average manual car driver takes between 500 ms and 1 s to perform vertical gear changes (i.e. 1st-2nd, 3rd-4th, 5th-6th) and 1 - 2 s to perform horizontal gear changes (i.e. 2nd-3rd, 4th-5th).
In Japan, 91,000 vehicles were recalled in 2013, specifically those with the dry 7-speed DSG (DQ200). [ 59 ] [ 60 ] Same year the Volkswagen Group recalled 1.6 million vehicles worldwide with the dry-running 7-speed dual-clutch transmission, type DQ200, including 257,000 in Germany.

Gear shift lever on a motorcycle (above the toe of the rider's boot) A sequential manual transmission is unsynchronized, and allows the driver to select either the next gear (e.g. shifting from first gear to second gear) or the previous gear (e.g., shifting from third gear to second gear), operated either via electronic paddle-shifters mounted behind the steering wheel or with a sequential ...
On Jan. 25, 2025, the first retail production 2025 Chevrolet Corvette ZR1, VIN 001, sold at the Barrett-Jackson Scottsdale Auction for $3.7 million.
Almost all quickshifters for upshifts on motorcycles work on the same basis: a microcontroller detects the gear shift action via a sensor, calculates the shift timing, and momentarily cuts off the ignition, resulting in a reduction of the load at the transmission allowing the engine speed to match the transmission speed of the next gear and permit the gear to slip (and engage) into place.
The test also scanned for physical traits, like body size and coat color, but not personality traits like the others did. Where Basepaws shines, though, is its wealth of educational content ...
