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.
The design of a four-wheel drive vehicle
ensures the capacity of transmitting torque from the engine to all four wheels
of the vehicle. Structural arrangements of 4WD systems allow realizing the full
power potential of the car, its road handling, active car safety. The
four-wheel drive car can be abbreviated as 4x4, 4WD, or AWD.
Progress does not stand still as new technologies emerge in the automotive
industry every day. Special attention should be paid to significant achievements
of automobile engineers in the field of automobile technologies. Pre-selective
transmission technologies gained significant popularity with the release of
DSG6 and DSG7 transmissions designed by Volkswagen.
Three
years ago, at the Geneva auto show Toyota Motor unveiled its hybrid Lexus LC500H
model. At first sight, there is nothing special about this grand tourer, but
when you take a look at the powertrain specification, you may be surprised by
its unique and innovative transmission setup.
In
the second half of the 90s, marketing
specialists of Toyota noticed that automated (or robotic)
manual gearboxes gave been gaining popularity in Europe. Thus, the company decided to develop its own robotic gearboxes FreeTronic and Multimode, which are considered by many experts and car
enthusiasts to be far from the most successful Toyota designs.
If
you've ever considered Porsche models as an option when buying a car, you must
have come across an unusual abbreviation PDK, when examining Porsche’s
specifications. This advanced transmission solution, built in-house, ensures extremely
fast gear shifting and found application in numerous Porsche models for a good
reason.
There is a
family of automatic transmissions, which surprises even ardent admirers of
manual transmissions by its reliability. We are talking about the ZF8HP family
designed and manufactured by the German company ZF Friedrichshafen.
Clutch assembly is not an easy task that
requires time and perseverance. To avoid frequently needless and expensive
replacement of the whole unit, prior estimation is a must. In such cases, ZF
Aftermarket is eager to share its solid experience in the transmission repair
with the repair shops, helping to prevent errors specifically related to clutch
plate mounting.
CVTs have one “mysterious” component named a fluid
degradation counter (or just fluid counter), which raises many questions among
auto enthusiasts. Owners of cars equipped with CVTs constantly argue whether it
is necessary to reset the oil counter after the oil change.
In the
early 50-es, automatic transmissions were widely used on many American cars. The success of this innovative transmission
didn’t go unnoticed in the USSR. In this article, we will consider the main
stages of transmission technologies development in the USSR on the examples of major
Soviet carmakers ZIL, GAZ, and VAZ.
Automatic transmission failures frequently manifest
themselves in kicks and jerks when shifting gears (car with automatic
transmission starts to consume more fuel).
There
may be many reasons for the abovementioned symptoms, but a specific reference
should be made to the automatic transmission cable.
In this article, we will consider the process of
transmission adjustment, or, to be more precise, transmission cable adjustment
and its peculiarities.
As a rule, many car owners assume that various
technical liquids and lubricants, including transmission fluid, do not have an
expiration date , i.e. they can be stored as long as necessary before intended
use. But it is a mistaken belief, because the shelf time of transmission fluids
is limited by manufacturers. In this article, we will consider this issue in
more detail.
Design solutions implemented in Honda cars
frequently surprise the automobile community by peculiar technological
approaches. One of the brightest examples is the design of automatic
transmissions developed by Honda engineers. In this article, we will consider the main
features of Honda automatic transmissions, their pros and cons, as well as the
specifics of their maintenance.
