In a car with a manual transmission, the clutch is a very important component as it connects and disconnects the drive shafts. Even under normal use, the lifespan of the clutch is typically shorter than the car. When you change gears, the clutch also suffers wear and tear. How long can a clutch in a manual transmission last?
Some cars owners may see their car clutches fail at 30,000 miles or below. This usually happens to drivers who are typically rough in changing gears. There are car owners who may see their clutch start malfunctioning at around 50,000 miles. Drivers who are usually smooth with their gear changes may see their car clutches live until 100,000. In an environment where frequent gear changes aren’t needed – along drivers who are efficient in gear shifting – can see some clutches reach a lifespan of more than 100,000 miles. Thus, there is really no exact number with regards to the lifespan of a car clutch.
While nothing is really sure on the specific lifespan of a car clutch, there is one thing that is certain – clutches are really susceptible to wear and tear, even more than the car itself. Thus, a clutch usually fails even before the car dies. This means a clutch may have to be replaced at one point of a car’s life. The actual lifespan of a clutch depends of many variables.Read the entire article How long does your car clutch last?
When driving a car with a manual transmission, it is imperative to first depress the clutch pedal before up-shifting or down-shifting gears. Once this pedal is depressed to the floor, the clutch disengages, thereby disconnecting the engine from the transmission. At this moment, the driver can shift up or down the gears. But do you know you can shift gears in manual transmission without having to use the clutch pedal?
Typically, you have to depress the clutch pedal to disengage the clutch. Shifting gears while the clutch is engaged isn't advisable as this could damage the gears, especially their teeth. Disengaging the clutch essentially cut off the power supply from the engine. Since the shifting process doesn’t have to work again power and torque, the gears won’t get damaged. Once you take your foot off from the clutch pedal, the clutch engages once again to connect the engine to the transmission.
However, it is possible to shift gears up or down without having to depress the clutch pedal. This means that you are shifting gears while the clutch is still engaged, and the engine is still connected to the transmission. Being able to shift gears without using the pedal could mean a lot when you are driving and the clutch seemed to have failed.Read the entire article Slip-Shifting – How to drive a manual transmission car without using the clutch
Within the next four years, Toyota plans to bring its latest drivetrains in about 60% of all its vehicles sold in China, Europe, US and of course in Japan. The new hybrid technology is said to boost the car’s acceleration that will help reduce fuel consumption.
From what was reported earlier, Toyota will be introducing its latest 10-speed gearbox along with the new engine that saves on fuel by at least 20%. Beginning next year, Toyota will be using its brand new engine technology, which will come with the latest hybrid system. Among its new innovations are 2 new transmissions and a 2.5 litre 4-cylinder engine.
Joining the new line of power plant (otherwise known as Toyota’s “Dynamic Force Engines”) is none other than its 2.5 litre four cylinder with direct injection. This by far is the most energy efficient of all engines bringing at least 41% energy efficiency for hybrids and about 40% for gasoline fueled models. In other words, when less energy is consumed due to internal friction, the engine is more capable of sending more HPs to the wheels.Read the entire article Toyota to launch new 2.5 L petrol engine, hybrid system and 10-speed gearbox
The five-door, four-seater Renault Twingo will now be available with French carmaker’s innovative gearbox, the Efficient Dual Clutch transmission (EDC). This transmission, which will be paired with the vehicle’s TCe90 engine, is basically an automatic dual dry clutch transmission dispensing that requires a clutch pedal.
It features the PRND gearshift control with an 'up/down' shift mode. An electronic control unit is tasked to select the ideal gear. In addition, the gearshifts are automatic. The availability of the EDC transmission on Twingo should mean that this gearbox can now be fitted on majority of the range, for just £900 more than the equivalent manual version.
With a very quick shift time of 290ms, the EDC transmission allows for comfortable and smooth trips. This transmission features a ‘creep’ control, which should prove to be a great help during crawling traffic, as it helps pull the vehicle away gradually when the driver steps off from brake pedal.Read the entire article EDC Transmission is now available on 2016 Renault Twingo
Honda Motor Co. has ordered its dealers in the United States to stop sales of a nine-speed version of its 2015 Acura TLX as the parking lock may fail to engage and the sedan may roll away even while in park mode, the carmaker said in a statement on its Web site. Honda is planning to commence sending recall notifications to customers on Jan. 6, 2015.
The stop-sale order comes after Honda recalled its Fit models in Japan over software glitches and at least 13 million vehicles fitted with possibly faulty Takata Corp. airbags. The problem will be the latest for Honda since President Takunobu Ito took 20-percent pay cut for three months to show apology for quality issues that has been dogging the Japanese carmaker.
Satoru Takada, an auto analyst at Toward the Infinite World Inc., told Bloomberg that Honda is creating “a lot of challenges for themselves” and is over-stretched. He noted that recalls related to Takata airbags and the Fit has made Honda extremely sensitive about any possible quality issue.Read the entire article Honda issues stop-sale order for 9-speed 2015 Acura TLX in the US
Volkswagen Group has started producing its dual-clutch transmission at its new site in Tianjin, China. VW invested EUR265 million (CHY2 billion) into the plant, which has the capacity to build up to 450,000 units of the carmaker’s direct-shift gearboxes (DSG) annually, and eventually 1.2 million units by 2016. VW intends to set up a test center in Tianjin in 2016 for all DSGs built in China.
The carmaker opened its first Chinese DSG site in Dalian, China in 2010 and has been using these transmissions mostly in locally built VW and Skoda models. In 2013, Volkswagen had to call back 384,181 vehicles fitted with the DSGs in China following reports from some owners over abnormal vibrations, loss of power and sudden acceleration.
VW also had to implement smaller recalls in Japan, Singapore and Australia. A dual-clutch gearbox works like two automatic transmissions side by side.Read the entire article Volkswagen Group begins DSG production in Tianjin, China
Nissan Motor Co. has issued a recall of 14,438 units of model years 2014 Infiniti Q50 and Q70 luxury hybrid sedans around the world over potential software and transmission issues. The sedans are being recalled since their electric motor may stop running due to a communications error between the motor inverter and transmission control module, according to the carmaker and documents posted at the Web site of the United States National Highway Traffic Safety Administration (NHTSA).
The recall covers 7,539 units of the Infiniti Q50 and Q70 hybrid sedans sold in Japan, 5,412 in the US and territories, and the rest in other markets. The stall-like condition may happen when the electric motor stops working, thereby increasing the risk of a crash, according to the NHTSA documents.
The problem, however, does not manifest when the sedan is driving highway speeds while the internal combustion engine is being employed. The Japanese carmaker discovered the issue following a "field incident" in Japan in August, although it was not aware of any incident in the US market, according to NHTSA documents.Read the entire article Infiniti recalls over 14,000 hybrid sedans to fix software and transmission issues
The eight-speed automatic gearbox that will initially see action in the 2015 Chevrolet Corvette should be used more in other vehicles built by General Motors, according to a forecast by IHS Automotive, as obtained by Automotive News. IHS expects GM to produce almost 200,000 eight-speed transmissions – dubbed as 8L90 -- for the Chevrolet Silverado and GMC Sierra pickups annually in the next two years.
In 2015, GM will offer a lower-torque version of 8L90 in some Cadillac ATS and CTS models and the Chevrolet Camaro. IHS likewise expects that the 8L90gearbox to be offered in other models like the Chevrolet Colorado and GMC Can-yon midsize pickups (2016); and the Chevrolet Express and GMC Savana cargo vans (2018).
The carmaker disclosed in August that it would offer 8L90 in some 2015 Silverado and Sierra models, as mated to a 6.2-liter V-8 engine. GM global product chief Mark Reuss divulged last months that transmissions having more gears will be "a big part” of GM’s product lineup.Read the entire article GM’s new 8-speed automatic gearbox to be used in other models
Aston Martin Vanquish and Vanquish Volante models are now updated for the 2015MY and as expected, the vehicles are faster and more efficient. For the 2015MY, Aston Martin Vanquish and Vanquish Volante are now available with a new Touchtronic III 8-speed automatic transmission developed by ZF, which is bolted to the 6.0-liter V12 engine delivering 568 bhp (+3 bhp over its predecessor) and 465 lb-ft (630 Nm) of torque at 5,500 rpm.
As a result, the Vanquish is much faster as the 0-60 mph time dropped from 4.1 to 3.6 seconds (3.8 seconds 0-100 km/h). Meanwhile, fuel economy was improved by 7 percent in the US combined cycle and CO2 emissions dropped by 10 percent to 298 g/km.
Top speed was improved too and the 2015 Aston Martin Vanquish is capable of doing over 200 mph or 320 km/h. And this is not all as the new transmission is 3 percent lighter than its predecessor.Read the entire article 2015 Aston Martin Vanquish, Vanquish Volante receive new 8-speed transmission

Jason Stoicevich, head of the Fiat brand in North America, is confident that an optional automatic gearbox for the Fiat 500 Abarth would attract more customers. He remarked that Abarth’s sales in the US surged 16 percent so far this year, despite offering only a manual transmission.
He said that those who don’t buy the Abarth usually bemoan the lack of an automatic transmission. “That was the only reason for rejection,” Stoicevich said. Chrysler Group started producing Fiat 500 Abarths fitted with six-speed Aisin automatic transmissions this month in Mexico.
Matt Davis, chief of marketing for the Fiat brand in North America, quipped that Abarths with automatic gearbox are expected to be rolled out to Fiat’s US dealers in July. Davis said that the automatic transmission opens up a “breadth of opportunity for millennials and Gen Xers” who don’t know how to drive a manual or prefer an automatic.Read the entire article Automatic gearbox on Fiat 500 Abarth seen to attract more buyers in US
After showing the Multibeam LED headlamps, Daimler officially introduced the 2015 Mercedes-Benz CLS Facelift. As expected, the new car comes with a redesigned front section that consists of a new front grille, redesigned headlights as well as a brand new bumper. At the rear, we find redesigned taillights as well as a new rear bumper.
Both the CLS Coupe and CLS Shooting Brake come as standard with all-LED headlamps, while as an option the German manufacturer offers the Multibeam LED headlamps. As we said, the Multibeam LED headlamps is similar to Audi’s Matrix LED headlights but as usual, the United States will not receive them due to the rules that need separate high-beam and low-beam modes.
Each headlight features 24 high-performance LEDs, offering the best visibility on bends and roundabouts. The roundabout light is unique as it activates the cornering light function modules on the left or right before entering a roundabout in order to provide the best visibility. The headlamps are connected to the navigation system that provides the details of the locations of roundabouts along the route.Read the entire article 2015 Mercedes-Benz CLS Facelift arrives with new design, 9-speed transmission
Chrysler Group is still recalibrating the software that operates the nine-speed automatic transmissions the carmaker plans to use for all of its front-wheel-drive vehicles. The carmaker has commenced a new software recalibration for over 100,000 Jeep Cherokees built before May 5, 2014, in order to resolve continuing issues with the shifting of some of the nine-speed gears.
In 2013, Chrysler was forced to delay the rollout of the Cherokee for nearly two months to tweak the software. A May 15 technical service bulletin calls for technicians to implement a five-minute software reset or "reflash" and, in certain cases, an "adaptation drive learn."
This entails test driving a Cherokee for around 78 minutes to ensure that it is shifting properly. Like other electronic transmissions, the nine-speed gearbox learns the driving habits of its main driver, adapting to the shift patterns accordingly.Read the entire article Chrysler issues reflash of transmission software for 2014 Jeep Cherokee
It appears that BMW will not follow other carmakers and build nine-speed or more and will focus on smaller three-cylinder power. Klaus Frolich a.k.a. BMW’s small and midsize cars boss said that the current eight-speed automatic transmission, seven-speed dual-clutch gearboxes and six-speed manual transmissions are the perfect combination.
According to Frolich who spoke with AutoExpress during the UK launch of the X4 and 4-Series Gran Coupe, BMW ran some tests and the difference between the six-speeds and eight speeds is seven or eight percent.
As a result, the benefit for nine-speed transmission instead of eight is almost 0 percent. In addition, the 9-speed transmission also adds weight and costs.Read the entire article BMW will not build nine-speed transmissions, will focus on three-cylinder power
Fiat plans to offer six-speed Aisin automatic transmission as an option in 2015 Fiat 500 Abarth and Turbo models in the United States, according to Jason Stoicevich, head of the brand in North America. The option will be available after the models go into production in July. Brand executives have remarked the automatic will further the models' sales appeal.
The Fiat 500 Abarth, which has been available only with a manual gearbox since it was launched in 2012, accounts for around 15 percent of Fiat 500 sales. According to Stoicevich, one of the factors why Fiat customers don’t opt for the Abarth is the lack of automatic, noting young people just “don't drive a manual transmission."
He added that the addition of an automatic could boost sales of the performance versions by up to 50 percent. Stoicevich remarked that versions of the MY2015 500 will also feature a new 7-inch electronic display in its instrument cluster.Read the entire article Automatic gearbox is now optional on 2015 Fiat 500 Abarth and Turbo
Chrysler chief executive Sergio Marchionne is still committed to employing the new nine-speed automatic transmission on its front-wheel-drive-based models even though software glitches in the gearbox was the prime cause of a two-month delay of the launch of the 2014 Jeep Cherokee.
Chrysler, which licenses the nine-speed technology from ZF Friedrichshafen, will use the transmission in the 2015 Chrysler 200 and Jeep Renegade. Chrysler said it continues to refine the transmission's operating software in the Chrysler 200, confident that the model would be in dealerships as promised in the second quarter.
Unlike the Cherokee, the 200 regularly uses the most fuel-efficient ninth gear during typical operations. Marchionne has said that the nine-speed is the “shortest, most complex transmission you can buy in the marketplace," adding that it features a number of wonderful attributes.Read the entire article Chrysler CEO committed to use 9-speed gearbox on all fwd models

Honda’s refreshed 2014 Civic lineup will be fitted with continuously variable transmissions or CVT. Any automatic Civic model will now be equipped with a CVT. It is estimated that around 90 percent of the total Civic model mix in the United States are fitted with automatic transmissions, which means that Honda dealers will have to convince around 300,000 Civic buyers annually that a CVT is a good buy.
Jay Guzowski, Honda product planning manager, remarked that the CVT “will not interrupt the usual experience of a car.” Since CVT does not have fixed gear ratios, it does not suffer “shift shock” during acceleration. Guzowski said that a CVT allows for a wider “ratio range” and more linear acceleration feel than a transmission with fixed gears.
Likewise, a 2014 Civic with CVT will have 30/39 mpg fuel ratings compared to 28/39 mpg for a 2013 Civic with five-speed automatic gearbox. However, drivers may find the “rubber band” sensation of a CVT’s pulleys and cones disturbing like a slipping clutch.Read the entire article 2014 Honda Civic to have continuously variable transmissions (CVT)
The 2014 Chevrolet SS is powered by a 415-hp LS3 V-8 and six-speed automatic as standard but for those who want more, there may be other variants depending on how well the existing model sells. In an interview with Automotive, Chevrolet Performance Cars marketing manager John Fitzpatrick said that there could be a model equipped with a manual transmission.
There may even be a supercharged engine. The Pontiac G8, which is the SS’ predecessor last sold in the U.S., failed to meet the projected 20,000-30,000 units a year.
As a result, the SS now has a lower sales target of 3000 units a year. If sales of the single automatic/LS3 configuration exceed expectations, versions like a supercharged model and a manual transmission option may be brought over from Australia to the U.S.Read the entire article 2014 Chevrolet SS might receive manual, supercharged variants
