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.
A torque converter (TC) is an indispensable
part of modern automatic transmissions and CVTs which plays an important role
in their operation. In many cases, TCs fail much earlier than the automatic
transmission. Frequently, the problem resides in the seal leakages. We will
consider this problem in more detail.
In terms of operation, cars equipped with
automatic transmissions differ from cars with manual transmissions, and it
especially becomes obvious in winter time. That is why winter driving with the
automatic transmission requires strict adherence to some rules.
Nowadays, at the time of rapid developments of
technology and innovations in the field of car transmissions, shift from manual
to automatic (and more complex) transmissions creates new opportunities for first-time
entrepreneurs and skilled transmission repair specialists to try and succeed in
the transmission repair/rebuilding business.
The abbreviation “DSG” stands for Direkt Schalt
Getrieb and literally means “Direct Shift Gearbox”. In fact, this is only one
of many types of preselective automated gearboxes equipped with two clutches.
Basically, DSG it is the manual transmission with the automated control.
Today,
most drivers choose cars with automatic transmissions, but not all car owners
are familiar with elementary operating rules of automatic transmissions. In this article,
we will consider what can go wrong with this crucial car component and what the
owners should do to prolong its service life.
Transmission Control Module in Automatic Transmissions: Location, Functions and Common Repair Issues
The transmission control module (TCM) is
considered to be one of the most complicated structural elements of the
automatic transmission. It consists of numerous microcircuits and chips which
analyze hundreds of transmission parameters in real-time mode.
When driving a car equipped with the automatic transmission
one may wonder what is a kick-down and how it should be used. This is particularly
true for novice drivers or experienced drivers, who only recently moved from
manual to automatic transmission. Let’s provide insight into this helpful
operation mode.
Failure of the automatic transmission often
turns out to be the case when car owners decide to replace the broken automatic
transmission with the less expensive manual transmission. In this article we
will consider the implementation of this procedure and how to do it by
yourself.
Like
many e-cars, the Tesla Model S has no need of numerous car components including
a transmission, gears and a clutch. Therefore, this car has fewer elements
prone to wear or failures requiring repair. In this
article, we will consider the powertrain solution implemented in the Model S.
In the process of the car movement, the
automatic transmission is subjected to significant loads and requires a proper
and high-quality cooling. In this article we will consider the automatic
transmission cooling system design and its operation principles.
Continuously variable transmissions (CVT) made
a true revolution in the world of automotive industry. However, CVTs weren’t used widely due to lack of synchronization between
the driving shaft and other internal parts. This issue led to cutting of
gearing teeth, lack of alignments, and complete wedging. This major problem was
solved with the help of the stepper motor specially designed for CVTs.
The car automatic transmission consists of
numerous moving elements which require not only high-quality lubrication, but
also efficient cooling. The automatic transmission oil pump helps to maintain the
necessary system pressure and to increase the efficiency of lubrication with
increasing RPM rate of the engine shaft.
