Technical Transmission General
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.
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
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.
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.
Recently,
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
sprint. The
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.
Rapidly growing share of automatic
transmissions in modern vehicles made it possible to increase the level of
comfort on the road, optimize the process of gear shifting and fuel economy,
and to implement some features related to the road safety. All these benefits
are particularly important on urban roads with heavy traffic. But why designs
of automatic transmissions still include a manual mode of operation?
