Manual transmissions were the first and most common type of transmission to be fitted in cars to benefit from different gear ratios between the respective propulsion of engine and drivetrain. They basically involve the activation by the driver of the clutch by a foot pedal, the positioning of gears by a gear stick, and the respective coordination of the fuel supply through a throttle pedal.
Manual transmissions cost less to manufacture and their reparation in case of malfunction is less complex and costly than that of automated ones. As compared with fully automated devices, it also allows for a potential greater fuel efficiency (albeit not necessarily) as the driver can judge what especial conditions of driving allow for taller ratios and lower supply of fuel. The risk of engine breakdown due to over-revving has additionally been significantly reduced through the fitting of electronic rev-limiters.
More significantly, however, the greater advantage of manuals lies in the substantially different driving experience. Automobiles with manual gearboxes situate the driver in command of all the important functions of the vehicle, such as gear selection, amount and duration of clutch activation, fuel supply, all of whose related combinations allow for an infinite range of subtle variations of the dynamics of the machine. Automobile enthusiasts, that is, individuals related to vehicles seeking the sensorial experience of driving for its own sake rather than as a means of transport or of merely attempting to move measurably faster, tend to value all the mechanical operations implied by active driving rather than seeking promised marginal gains in speed by the delegation of functions to the vehicle's automated systems. The experience of directly controlling and operating the main variables and functions of the vehicle and for the driver to be organically integrated with the whole of the machine is believed to be of greatest appeal to car enthusiasts.

CVT Paddle Shifting vs Formula 1 PDK (Doppelkupplung)
CVT Paddle Shifting vs Formula 1 PDK - (Doppelkupplung Dual-Clutch)
Get the book here:
Ok, so what does CVT technology has to do with Formula-1 technology? The
answer is, you're right, absolutely nothing. However, in an ever increasing
move to adapt and accept CVT technology, some manufacturers have installed
the paddle style Formula-1 shift on CVT vehicles. This move is a complete
negation of the benefits of CVT, and a waste of money for the consumer. In
this article we'll explain the differences between the two technologies and
how they work, to allow you to make a decision. We encourage you to go
elsewhere in this series, for more on CVT technology.
The newer semi-automatic dual clutch transmissions, are a direct result of
years of Formula 1 technology. These transmissions are directly related to
the manual, standard stick shift dry clutch transmissions that we all know.
However, the semi- automatic, also known as PDK for their German name,
effect the actual shifting using either servo hydraulic, or electric
actuators, using a paddle shifter on the steering wheel. This is exactly
the same technology used in Formula 1 racing cars. Lots of automotive
technology first starts in the Formula 1 circuit, then trickles down to
mass produced cars.
Paddle shifted PDK semi-automatic transmissions, are the latest and most
advanced gearboxes today. These units have all the benefits of a manual
transmission, including fuel economy, have no torque converter, no gear wet
clutches, and are fully computerized and able to operate as a normal
automatic. There are two types of paddle shifted PDK semi-automatic
transmission, the single dry clutch, and the more advanced ... Get the

Which is better, manual or automatic transmission? Paddle shift or stick shift? Ending the debate!
Which is better, manual or automatic transmission? Paddle shift or stick
shift? Ending the debate!
For the true enthusiast, the clutch pedal and gear stick or shifter are a
JOY to use...NOT a burden. Traffic is the one exception but we are talking
about the car enthusiast. We drive fr PLEASURE, NOT to get to work or get
groceries. So traffic is not an issue when it's 7AM on a Saturday or Sunday
and you are headed to your favorite country road.
For the enthusiast, the clutch pedal is a PLUS not a minus. It is a
critical part of what makes driving a stick shift an art. Automatic is
email and manual is a hand written note. A dying art that is much more
involved and personal than email.
Making a perfect shift, makes me smile like NO paddle shift will EVER do!
Manual is a piano played with a live band, automatic is one man with a
Casio keyboard in his basement with automatic accompaniment generated by
the keyboard. The feeling of playing a complex piece correctly dwarfs any
reward of pressing ONE note and having the Casio keyboard play a bunch of
Is a paddle shift a manual transmission?
Being able to request gears manually does NOT make a transmission
automatic. Remember in the automatics from the 80s you had "2" "L" "R"? So
automatics have allowed you to "change gears" since the 80s. This is just
like modern paddle shifters do.
NOTE: A sequential gearbox is NOT the same as the classic automatic
gearbox, but the point is, you could ALWAYS select/request gears in
automatics. So the ability to SELECT gears does not make it manual. You
need the ability to physically disengage the clutch by moving the throw out
bearing and also to physically change the actual gears. This is all
mechanically done, not electronically. It requires focus, finesse,
strength, timing and skill and it's rewarding to do correctly.

Shifting gears, 12 speed Volvo
More of me showing of. . . .
sharing with youtubers, driving modern heavy vehicles.Today I'm in an 2007
FM12 Volvo, fitted with Volvo's own electronically controlled 12 speed
automatic/semi automatic clutchless gearbox.
I must admit I didn't like the Idea at first (I'm a roadranger man myself),
but after spending a couple of days with this, I was hooked, real bit of
trick gear, others European truck manufactures have similar concept's
(likely sourced from ZF), HEAPS more drivable than the self shifting
Roadranger, faster and smoother
than the 'BENZ.

R8 R tronic
Today only about eight percent of the new cars purchased in the U.S. are
bought with manual transmissions. Compare that to Europe where around eight
out of ten autos sold are stick shifts. The overwhelming preference for
automatics in America means that even dedicated sports cars sold here had
better offer an automatic.
And that's just what Audi did when they launched the R8, their mid-engine
supercar. It comes standard with a slick, six-speed manual transmission but
they also offer an optional automatic dubbed R tronic. Unfortunately the
$9,000 they charge for the R tronic isn't the worst part about it.
