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.
What are typical transmission failing symptoms and what are the reasons: Slipping gears, no shifting, hard shifting, shuddering, shifting delays, this in not a full list of strange bahaviour of your automatic transmission, let us explain.
Car
manufacturers have always been looking for ways to make their cars more
cost-efficient and customer-friendly, developing less expensive car components
(engine, gearbox, etc.) in hope to increase the take rate of their products. In
this article, we go back to 1968 when Chevrolet released its semi-automatic
transmission named “Torque-Drive”.
To eliminate
one of the most common transmission issues – jerks during gear shifting, an automatic transmission design includes a transmission brake band. The
automatic transmission brake band is necessary to block planetary gear elements
for a short time. In this article, we will consider the main purpose of the transmission brake
band, its design peculiarities, place of installation, and why it is necessary
to adjust this element.
The
Super Shift transmission, also known as Twin-Stick, is a manual gear shifting solution
designed by Mitsubishi in the late ‘70s. This solution found application
on several Mitsubishi models, which were produced mostly in the ‘80s. This unit
is notable for some design peculiarities: this 2WD unit has 8 forward gears.
The manual 2020 Toyota Supra is finally here , as the EAG team has managed to integrate a 6-speed manual
transmission in the Supra design. In this article, we’ll take a closer look at
all stages of the transmission swap process with the help of videos from EAG’s
youtube channel.
Not only modern highly-sophisticated units can leave a lasting
impression and that there has never been some place for ingenuity in the field
of the transmission development. For instance, we can look back to the 1980s
when the Chevy Corvette C4 hit the market with a mysterious 'Doug Nash 4+3' manual transmission.
Sometimes it happens that your car can get
stuck in the middle and the only way out is to tow it to the nearest repair
shop. It can become a real problem for owners of CVT-equipped cars, as not all
drivers know how to do it accurately without any harm to a pricy transmission
unit. In this article, we will consider the main peculiarities of CVT
transmissions and how to tow a CVT-equipped car properly.
A crucial role in operability of CVTs is given
to specific fluids (CVTF) used only in variable transmissions. These fluids
have great lubricating properties and at the same time they prevent the belt
from slipping on the pulleys. The achievement of such an objective is possible
thanks to the use of unique packs of additives. But sometimes young drivers of
CVT-equipped cars often wonder whether it would be safe to use automatic
transmissions fluids (ATF) in their CVTs.
The most common symptom of the automatic
transmission malfunction lies in kicks and jerks during the process of gear
shifting. In this article, we will explore the main causes of kicks and jerks
in automatic transmissions and give some recommendations on how to deal with
such issues.
A well-known car enthusiast Matt Farah
has recently proved technical superiority of automatic technologies, showing that it’s real to “clutch kick” with Porsche’s PDK transmission in a 911 GT3
RS.
Nowadays,
many modern cars (passenger cars as well as SUVs) more and more often are
equipped with a CVT transmission instead of a conventional automatic
transmission. Transmission fluid in CVT transmissions plays
no less important role than in conventional automatic transmissions. Thus,
well-timed changing of transmission fluid in the CVT unit is considered to be a
key maintenance procedure.
Today, many car owners can quickly and easily
change TFs in their cars. As a rule, after each TF change they have a canister
full of used fluid that lost its useful qualities. Subsequently, many drivers
frequently do not know what to do with used oil and how to dispose of it. It
this article, we will consider what should be done to used fluid.
