What is 6-speed & 5- Speed Manual Transmission?

What is 6 Speed Transmission?

In the automotive world, 6-speed refers to a transmission with 6 forward gears. The most common 6-speed transmissions are traditional manual units where the driver actuates a clutch with her foot while shifting through the gears. In more recent times, 6-speed automatic and sequential-manual transmissions have worked themselves onto passenger cars as well.

Six-speed manual transmissions started to emerge in high-performance vehicles in the early 1990s, such as the 1990 BMW 850i and the 1992 Ferrari 456. The first 6-speed manual transmission was introduced in the 1967 Alfa Romeo 33 Straddle.

The three-shaft transmission is also very compact (length 345 mm) and light (dry weight 46 kg) and incorporates a number of special features for particularly pleasant gear shifting. An integrated magnet on the gearshift shaft is detected by a Hall sensor. The idle position is identified in this way, making the start/stop function possible. The signal for reverse gear activates the reversing lights.

The large spread of 6.7 allows a reduction in engine speed while at the same time ensuring that sufficient tractive power is available when moving off with a fully laden A-Class and trailer up to a gross weight of 3.4 tones. The clutch is operated hydraulically and the gears are actuated via cables.

The overhead camshaft with third and fourth gears and the reverse gear do not run in the oil bath. This reduces drag torque, thus facilitating gear shifting at low temperatures in particular. The three-cone synchronization of the first two gears serves the same purpose, while the following gears are provided with two-cone synchronization. The weight-optimized cast aluminum shift forks are installed on anti-friction bearings on the shift rods, in order to reduce the shift forces.

6-Speed Manual Transmissions

The transmission has six forward gears and one reverse gear. All the gears on the main shaft, except reverse, have synchromesh engagement.

Traditionally, six-speed manual units have been reserved for high-performance cars. These transmissions feature closer gear ratios than a five-speed manual unit, allowing the driver to stay within the engine’s ideal rpm range.

Also, the sixth forward gear allows highway cruising without making the engine work so hard. The Mazda RX-8 is one of many such cars that use a six-speed manual. In more recent times, even some mainstream cars such as the 2011 Ford Fusion have offered six-speed manual units.

6-Speed Automatic Transmissions

Several years ago, automakers began adding extra gears to their automatic transmissions to maintain power and fuel economy throughout the rpm range. Traditional automatic transmissions differ from manual units in that they use a torque converter rather than a clutch in switching between gears. One such six-speed automatic unit, made by ZF, is found in the 2011 Hyundai Genesis Coupe.

6-Speed Sequential Manual Transmissions

The third type of six-speed unit blends traditional automatic and manual transmissions in that it uses either a single or dual-clutch when shifting between gears but does not require the driver to use the third pedal.

These sequential manual transmissions are usually shifted via paddle shifters mounted on the steering wheel in addition to having the capability to operate in fully automatic mode. They are ubiquitous on luxury cars and making their way into more mainstream cars as well.

What is 5 Speed Transmission?

The fixed and free gears can be mounted on either the input or output shaft or both. For example, a five-speed transmission might have the first-to-second selectors on the countershaft, but the third-to-fourth selector and the fifth selector on the main shaft.

This means that when the vehicle is stopped and idling in neutral with the clutch engaged and the input shaft spinning, the third-, fourth-, and fifth-gear pairs do not rotate.

The manual transmission is synchronized in all forward gears for smooth operation. It has a lockout so you cannot shift directly from Fifth to Reverse. When shifting up or down, make sure you push the clutch pedal down all the way, shift to the next gear, and let the pedal up gradually.

5-Speed Manual Transmission

Up until the late 1970s, most transmissions had three or four forward gear ratios, although five-speed manual transmissions were occasionally used in sports cars such as the 1966 Ferrari 166 Inter and the 1953 Alfa Romeo 1900 Super Sprint. Five-speed transmissions became widespread during the 1980s, as did the use of synchromesh on all forward gears.

5-speed automatic transmission

A 5-speed shiftable automatic transmission provides the ease of use offered by an automatic transmission coupled with the sportiness and increased fuel economy offered by a manual transmission.

Operation

A shiftable automatic transmission is mechanically an automatic transmission with an electronic override system that allows for driver shift control.

Function

Shiftable automatic transmissions do not have a clutch in the sense of a manual transmission. Instead, they use a torque converter to transfer engine power into forwarding motion through the wheels.

Types

Most shiftable automatics are regular automatic with electronic override. Some shiftable automatics are actually based on the principles of a manual transmission, using wet clutches that are controlled electronically.

Performance

A shiftable automatic allows the performance of an automatic transmission to be improved. Depending on driving style, the driver can change shift points to provide better fuel economy or better performance.

Expert Insight

Shiftable automatic transmissions are very reliable. With most vehicles offering this feature, it will not cost any extra to have a 5-speed shiftable automatic on your next vehicle.

What is the difference between a 5-speed and 6-speed manual transmission?

If you’re searching for differences between 5 and 6-speed manual transmissions, you probably have some experience driving stick.

For one, you shift more when driving a 6 speed. The gears on a 6-speed car are a bit more nuanced than a 5 speed. I’ve noticed that I tend to shift out of first (and second) much quicker in the 6-speed car.

From my own experience, and from what I’ve been able to glean on various car forums, another difference between a 5 speed and 6-speed car is when you’re cruising. If you’re on the open highway, chances are you’ll make your way up to 65 mph or more. This is where your sixth gear comes in handy. It’s essentially an overdrive that allows the car to operate at lower RPMs and save fuel.

FAQs.

What does a 6-speed transmission mean?

If a vehicle has a six-speed transmission, it means it has six forward gears. A six-speed typically means a manual transmission that has six gears, but both automatic and manual vehicles can have six-speed transmissions.

What is the advantage of a 6-speed transmission?

Efficiency. In recent 6-speeds, the extra speed from a 5-speed allows the engine to run at a lower RPM and save fuel, comparatively. This difference is most effective at highway driving speeds.

Is a 6-speed transmission better than a 4 speed?

6 speeds (and more) transmission offer more “narrower” gear changes at the given rpm range of an engine. Narrower gearing means the engine may not work hard to achieve significantly better acceleration. 4-speed manuals are relatively lighter, simpler, and costs less than 6speed manual transmissions.

What is a 6-speed automatic transmission?

A 6-speed automatic transmission uses six different drive gears to give you the best combination of fuel economy and power, as determined by the manufacturer. Since the transmission is automatic, the car determines when it needs to change gears and does it for you–all you have to do is drive the car.

Is a 6-speed automatic a stick shift?

Are 6-speed cars faster?

So, if you have a 6-speed manual transmission, you shift a total of 5 times from 1–6 while accelerating. To sum it all up: Having more “speeds” or gears in a manual (or automatic) transmission means you can drive faster at a lower RPM (engine speed).

Is 6-speed a v6?

None. Transmissions, even automatics, do not have cylinders. Automobile motors have cylinders. A six-speed automatic can be, at least theoretically, connected to a four, five, six, eight-, ten-, twelve-, or sixteen-cylinder motor.

When should I shift to 6th gear?

An overdrive gear allows your car to cruise at a high speed while maintaining low engine revolutions. You’ll use 5th or 6th gear for highway cruising at speeds of 60 mph to 70 mph and are ideal gears for best fuel economy.

How do you drive a 6-gear car?

Place the shift lever into the first gear, which on a six-speed manual will always be to the left and up. Second gear is straight down from first, third is up and over to the right a little, fourth is straight back down from third, fifth is up and over to the right a little and sixth is straight down from fifth.

Is 6 speed or 5 speed manual betters?

Does having 6 speeds really make that much of a difference. I sometimes wonder because my car (2006 Honda Civic) is only a 5-speed manual. Most newer cars now seem to be 6-speed manuals but I think that for most older cars like mine, 5 speed is common.

What is 6-speed manual with OD?

In the case of manual transmissions, overdrive is the highest gear of the transmission but has to be engaged by the driver. In a five-speed transmission, overdrive is the fifth gear; in a six-speed transmission, overdrive is the sixth gear; and so on.

What does 5 speed transmission mean?

The 5-speed transmission is a transmission or system of gears having five forward gear ratios. an automotive vehicle or bicycle having such transmission or system of gears. adjective. having five forward gear ratios.

Is a 5-speed automatic transmission good?

Nonetheless, we will highlight some of the benefits you will surely be getting in a 5-speed auto transmission fitted vehicle: You will enjoy better fuel economy because of its narrower speed range. The shift will feel better to handle because it will involve less speed change compared to a 4-speed type.

What is a 5-speed automatic transmission?

A 5-speed shiftable automatic transmission provides the ease of use offered by an automatic transmission coupled with the sportiness and increased fuel economy offered by a manual transmission.

Is a 5 speed or 6-speed better?

What is a 5-speed manual transmission?

The manual transmission is synchronized in all forward gears for smooth operation. It has a lockout so you cannot shift directly from Fifth to Reverse. When shifting up or down, make sure you push the clutch pedal down all the way, shift to the next gear, and let the pedal up gradually.

What is the difference between 5 Speed and 8 speed automatics?

A 5 speed has 5 gears and an 8 speed has 8. Otherwise, they work on basically the same principle. Not much to it, a 5-speed has 5 gears, and 8-speed has 8. Depending on the vehicle, more gears can mean either better fuel efficiency and acceleration or a higher top speed.

What’s the difference between 4 speed and 5 speed?

A 5-speed automatic with overdrive is the same thing, but with 4 gears being dedicated towards the lower end where higher torque is produced. This puts the engine in its optimum torque band more often when accelerating which will help improve the efficiency and low-speed acceleration across the gears.

What’s the difference between 4 speed and 5 speed automatic transmission?

Originally Answered: What’s the difference between 4-speed and 5-speed automatic? A 4 speed has 4 ratios and a 5 speed has 5. More gears will generally make a car smoother to drive and more efficient. It can also mean improved acceleration.

Can you put a 6-speed transmission in a 5-speed car?

By “taller” gear ratio, I mean that the engine will spin slower while driving the vehicle at the same speed (typically better for fuel economy). I will assume that you mean a transmission with more gear ratios to select, such as a “6-speed”, to replace one with fewer gear ratios, such as a “5-speed.” Yes, you can.

Why do some cars have 5 gears?

One of the most popular reasons for making an automatic transmission with more gears is for smoother acceleration and deceleration. When there are more gears in the transmission, closer gear ratios can be used. For the driver, that means the engine RPMs don’t vary as much when speeding up and slowing.
