The common five-speed shift pattern
A gear stick (rarely spelled gearstick),[1] [2] gear lever (both U.k. English language), gearshift or shifter (both U.S. English), more formally known every bit a transmission lever, is a metal lever attached to the manual of an car. The term gear stick generally refers to the shift lever of a manual transmission, while in an automatic transmission, a similar lever is known as a gear selector. A gear stick will normally exist used to change gear whilst depressing the clutch pedal with the left foot to disengage the engine from the drivetrain and wheels. Automated transmission vehicles, including hydraulic (torque converter) automated transmissions, automatic manual and older semi-automatic transmissions (specifically clutchless manuals), like VW Autostick, and those with continuously variable transmissions, do not require a concrete clutch pedal.
Alternative positions [edit]

Gear sticks are most commonly found between the front seats of the vehicle, either on the heart console (sometimes fifty-fifty quite far up on the dashboard), the manual tunnel (erroneously called a panel shifter when the floor shifter mechanism is bolted to the transmission tunnel with the center panel to comprehend upward the shifter assembly when used with a rear or front-wheel drive vehicle), or directly on the floor. Some vehicles accept a column shift where the lever is mounted on the steering column — in vehicles with a transmission four-speed gearbox such as 1950s Mercedes-Benz cars and all two-stroke Trabants, this is really a manual gear lever connected to the gearbox with a linkage. In automated transmission cars, the lever functions more similar a gear selector, and, in modern cars, does not necessarily need to have a shifting linkage due to its shift-by-wire principle. It has the added benefit of assuasive for a full width bench-blazon front seat (though some models with bucket seating as an pick include it). It has since fallen out of favor, although it can still exist found widely on North American-market pick-up trucks, vans, emergency vehicles (both constabulary enforcement and European monetary system - the cavalcade shifter is retained where a floor shifter is unfeasible due to mounting the mobile data terminal and ii-way radio), and "full-size" US sedans such as the Ford Crown Victoria. A dashboard mounted shift was common on certain French models such as the Citroën 2CV and Renault 4. Both the Bentley Marking Half-dozen and the Riley Pathfinder had their gear lever to the right of the right-mitt drive driver'southward seat, alongside the driver'southward door, where it was not unknown for British cars to also accept their handbrake. (Left-hand drive models received a column shift.)
In some modernistic sports cars, the gear lever has been replaced entirely past "paddles", which are a pair of levers, normally operating electric switches (rather than a mechanical connection to the gearbox), mounted on either side of the steering cavalcade, where one increments the gears up, and the other down. Formula ane cars used to hibernate the gear stick backside the steering wheel within the nose bodywork earlier the modern practice of mounting the "paddles" on the (removable) steering wheel itself.
Gear knob and switches [edit]
A knob showing the driver the position of each gear
A knob, variously chosen gear knob, shift knob, gear shift knob or stick shift knob, forms the handle for the gear stick. Typically the gear knob includes a diagram of the shift design of the gear selection organization, i.e. the positions to which the gear stick should be moved when selecting a gear. In some older transmission manual vehicles, the knob may contain a switch to engage an overdrive; in some automatic transmission vehicles information technology may incorporate a switch to appoint a special manner such as a sports manner or to undo overdrive. Both of the above-mentioned switches may as well be institute on the panel or on steering cavalcade stalks instead. Manual shifters on the steering column, if having simply 3 forward speeds, are typically chosen a "three on the tree". The everyman of these gears, if set at a much lower ratio than a typical 1st-gear ratio, is oftentimes called a "granny gear".
Starting the motorcar in gear with the clutch engaged causes it to lurch frontward or astern since the starter motor by itself produces sufficient torque to move the whole vehicle; this can be highly unsafe, especially if the parking brake is non firmly applied and can be injurious to the starter and drivetrain. Therefore, novice drivers are taught to rock the knob of a transmission gearbox from side to side earlier starting the engine to confirm that the gearbox is in neutral. For the same reason, modern cars require the clutch pedal to be depressed before the starter volition engage (though some modernistic vehicles have a button that disables the clutch start requirement if held downwardly when starting, for rare situations when starting the car in gear is necessary). The latter practice is also useful in extremely cold weather condition or with a weak battery, as it avoids the starter motor also having to turn over a gearbox full of cold and highly viscous oil.
Many automated transmission vehicles have actress controls on the gear stick, or very close by, which alter the choices fabricated by the transmission organization depending on engine and road speed, e.g. "sports" or "economy" modes which volition broadly speaking allow, respectively, for higher and lower revolutions per minute, before shifting up.
Some specialist vehicles have controls for other functions on the gear stick. The Land Rover Freelander introduced a button for that visitor'south Hill Descent Control system feature, which uses the brakes to simulate the function of a depression-ratio gearbox in steep descents.
Secondary gear levers [edit]
In some traditional four-wheel drive vehicles there can be a second gear lever which engages a low-ratio gearbox, used on tough terrain. Farther, a similar-looking lever called a transfer case switches betwixt two- and four-wheel drive, or engage differential locks; these are not "gear levers," however.
Shift pattern [edit]

The shift blueprint refers to the layout of the gears. In a typical manual transmission machine, beginning gear is located to the left, and forwards. In many trucks and some sports cars it is instead in a "dog leg" position, to the left and rearwards. There is usually a spring-loading to return the stick to the central position. Reverse gear is normally positioned in the all-time option of location to avert accidental appointment.
Manual manual [edit]
A typical manual transmission vehicle, with (for instance) v forward gears, will thus take seven possible positions: the five frontward gears, reverse gear, and a central "neutral" position. Some vehicles have a special button to prevent adventitious appointment of reverse. Others require that the lever be lifted, pressed down, or moved with extra forcefulness to engage reverse. In transmissions with opposite directly below 5th, in that location may be a mechanical lock-out preventing option of reverse other than from neutral, thus preventing a driver used to a six-speed manual from engaging contrary while trying to select sixth. Some transmissions also have an electronically controlled error-prevention safeguard that blocks the kickoff and sometimes the second gear from being selected if the vehicle is moving fast enough to exceed the engine'due south maximum RPM.
| Layout | Clarification |
|---|---|
 | This shift pattern is the well-nigh common five-speed shift pattern. This layout is reasonably intuitive because it starts at the upper left and works left to correct, top to lesser, with reverse at the end of the sequence and toward the rear of the car. |
 | This shift pattern is another five-speed shift pattern which tin can exist found in Saabs, BMWs, some Audis, Eagles, Volvos, Volkswagens, Škodas, Opels, Hyundais, virtually Renaults, some diesel Fords, most Holden/Vauxhalls and more than. The selection of the reverse gear is to prevent the reverse gear from being selected accidentally while the vehicle is in movement, causing catastrophic damage to the manual. |
 | This shift pattern, sometimes chosen a Dog leg shift design is used on many race cars and on older road vehicles with three-speed transmissions. The name derives from the up-and-over path between offset and 2d gears. Its use is common in race cars and sports cars, but is diminishing as six-speed and sequential gearboxes are becoming more common. Having get-go gear beyond the dogleg is beneficial as first gear is traditionally merely used for getting the car moving and hence it allows second and third gears to be aligned fore and aft of each other, which facilitates shifting between the two. As most racing gearboxes are non-synchromesh in that location is no appreciable delay when upshifting from showtime through the dogleg into second. This gear design tin can as well exist found on some heavy vehicles – such as lorries and tractors – in which first gear is an actress-low ratio for use in extreme standing-start atmospheric condition, and would see lilliputian use in normal driving. |
 | This shift pattern is a typical pattern for a six-speed transmission. Six speeds is the maximum usually seen in single range transmissions, nonetheless many semi-trucks and other large commercial vehicles have manual transmissions with eight, 16 or fifty-fifty twenty speeds, which is made possible due to multi-range gearboxes. In such a instance, Reverse is placed exterior of the "H," with a canted shift path, to forestall the shift lever from intruding too far into the driver's space (in left-paw bulldoze cars) when opposite is selected. College number of speeds in automobiles are rare occurrences, although examples practise exist, such equally the Porsche 911, which is equipped with a 7-speed manual transmission. |

 | Shift design for a iv-speed cavalcade shifter. Found like this in Peugeot 403 and 404 until September 1967. |
Automatic transmission [edit]
Automatic transmissions traditionally have had a straight pattern, adopting the archetype P-R-N-D gate, with "P" being to the front, topmost position (or "P" all the way to the left on a cavalcade-mounted shifter); the corresponding shift positions being:
- P = Park - manual is mechanically locked in position for parking, via a parking pawl.
- R = Reverse - reverse motion
- Northward = Neutral - no bulldoze applied to the wheels with the engine running
- D = Bulldoze - forward motility with fully-automatic operation in all gears.
All automatics apply some sort of manual override of the transmission, with numbered positions in descending lodge marked below (or to the correct) of "drive", which will forbid the transmission shifting to a gear college than the selected, just maintaining automatic operation between all lesser numbered gears. Such gates will appear equally P-R-Northward-D-three-2-1 for example. On some vehicles (mainly Japanese makes such as Honda, Toyota and Lexus) these numbered positions are replaced by a unmarried "L" (for "low") position, which will concur the manual in whatever lower ratio is required for climbing steep grades or for heavy acceleration: P-R-N-D-50.
More than modern automated transmissions have employed a "J-gate" (pioneered by Jaguar) where some gears are on the left-hand "arm", some on the right, and at that place is a sideways movement at the rear of the design. The 2d-generation Range Rover from 1995 used an "H-gate", with two parallel PRND gates on the opposing legs of the "H" for both loftier range and low range ratios, for normal and off-road driving, respectively.
Some modern gearboxes, namely manumatics, such as Alfa Romeo Sportronic, and Porsche Tiptronic, has a traditional automatic shift design to the right, with a special position to the left in which motility of the stick forrard and astern increments the gears up and down respectively. This can be useful in snow or dirt conditions, where it may be necessary to starting time from second gear.
Electronic gear shifts [edit]

With the advent of drive past wire (or more than properly, shift past wire) reckoner-controlled transmissions (particularly in the instance of automatics), the gear stick no longer needs to exist mechanically connected to the transmission unit itself, and tin, therefore, be made much smaller since there is no need to package either remote mechanisms or complex interlocking arrangements. This has allowed designers to replace the gear stick completely with either push button, rotary knobs (current Jaguar, Land Rover and Ford models are good examples of this), or a miniaturized gear stick on the center console. This can be seen in some Audis, BMWs and the Lincoln Continental. Japanese finger shift is another example. Information technology is a revival of an approach used in the 1950s by the Chrysler push-push PowerFlite and the Packard Touchbutton Ultramatic.
Special knobs [edit]
A shift knob likewise known as a gear knob, gear shift knob and stick shift knob is the physical interface between the gear stick and the commuter'southward hand. Made of many materials from simple plastics through to platinum, it comes in many shapes sizes and weights. OEM shift knobs are generally spherical in shape, often resembling a chess pawn when attached to the gear stick.
The shift knob's chief role is the ergonomical interface betwixt driver and the manu. The gear stick, equally the name implies, is ofttimes just a machined or cast aluminium or steel rod with or without threading the shift knob is fitted on its finish.[iii]
In recent years, manufacturers accept increased the variety of shifts knobs available to the consumer from inexpensive plastics to diamond-studded white gilded.[four]

Stylized shift knobs tin can exist plant on many types of vehicles. This aluminum, hand made, skull shift knob is mounted on a vintage Harley Davidson Knucklehead'southward "jockey shifter".
Weighted shift knobs [edit]
A weighted shift knob is a operation-driven aftermarket modification which entirely replaces the OEM shift knob and sits atop the aftermarket short shifter or OEM manual shift stick. Initially designed to exist used in tandem with a brusk shifter, it is increasingly existence purchased for stock stick shifts. The weight generally varies between 400 and 600 grams or more, depending on the cloth used. The principle of the weighted shift knob is to make the stick shifter top-heavy, thus increasing the throw momentum in society to decrease the time betwixt shifts. Weighted gear knobs are offered for auction by a multifariousness of North American-based manufacturers in many shapes and finishes, though they are significantly more than expensive than the commonly available aftermarket shift knob.
