General Transmission issues are varied and may include several causes and ways of treatment. Transmission experts share their knowledge and provide useful tips for the industry people to follow.
In the last couple of articles, we used terminology relating to pressure control solenoids such as PWM, Frequency, and Duty Cycle. In this article I thought I would go into depth on what these terms really mean and how they relate to
One of the most important
questions that anyone planning to buy a car has to answer is: "which
gearbox should I choose: automatic or manual?" Increasingly, car owners
choose the automatic option, which is not surprising: driving a car equipped with
an automatic is
Automatic transmission is currently installed on a large number of cars, but drivers are divided in their opinions about it. Some agree that it is extremely convenient, others say that it is more trouble than good. In particular, the claims relate to very expensive repair rates, because certainly, just as any other engineered element, it sometimes fails.
The main signs of the transmission position sensor malfunction are as follows: the engine does not start, the car does not move, the transmission switches to another gear when a certain gear is switched on, and the transmission goes into emergency mode. The transmission position sensor, also called the transmission range sensor, is an
The ability to instantly switch from two-wheel to four-wheel (all-wheel) drive without having to stop the car and without locking the wheel couplings is an invention that many of us have long taken for granted, especially during snowfall. Most modern cars are equipped with
A fleet truck can be easily overloaded if it does not come with the proper powertrain (engine+ transmission) combination, thereby resulting in increased expenditures for maintenance servicing. In this article, we will consider some helpful tips for owners of truck fleets on selecting truck components that have a significant impact on its performance, fuel economy and maintainability.
Not always bubbles on transmission dipstick are caused by insufficient ATF (transmission oil) level or its overflow. Problem can be more serious. As a rule, this symptom indicates certain
faults in the transmission operation. In
most cases, transmission fluid foaming is caused by abnormal ATF levels, but sometimes it is a result of transmission being damaged badly.
Today, it may be hard to believe today, but in the 80s, GM amazed the automotive market with cars with remarkable gear shifting mechanisms. These remarkable shifters allowed drivers of automatic cars to shift gears manually.
Most of automatic transmission issues stem from ATF, thus repair professionals pay special attention to ATF and its timely change. If potential risks of lower ATF level are intuitively clear to most of car owners (oil starvation can lead to numerous malfunctions or even failure of the whole transmission unit), the situation with the fluid overflow may be misleading.
Automatic Transmissions from Mercedes and their Typical Repair Issues. Mercedes presented its own-produced hydro-mechanical automatic transmission 722.2 in 1961. This transmission found application on W111 220 SEB/300 SE models. Instead of torque converters applied in modern automatics, this transmission was equipped with a hydraulic clutch/coupling. This transmission had been produced until 1983.
Automotive engineers have always been involved in a constant search for an innovative solution that can solve the problem of varying the gear between the driving and the driven members in a vehicle automatically and in an infinite number of different ratios. Long before the arrival of continuously variable transmissions (CVTs), engineers had something to offer in this field.
We get used to newspaper headlines such as “Manuals are dying”, “Stick shift is going extinct”, “Stick shift sales keep falling”, but it should not be assumed that the development curve of manual transmissions stopped at 4-5-speed units without any smart technologies. In reality, modern manual transmissions also can be equipped with a variety of remarkable features.
Top Gear arranged an exciting speed competition between the Tesla Model S
Performance and the new Porsche Taycan Turbo S. Despite the fact that the Tesla
had an edge in weight and power, the German car came out victorious in the 0-60
secret of this result lies in one important powertrain difference between these
two great cars, namely the transmission unit.
While cars equipped with manual transmissions gradually become outdated, many car manufacturer still integrate the feature allowing drivers to shift their own gears. How it can be implemented in automatic cars? The answer is simple – easy-to-use and efficient paddle shifters.
