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 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.
For car enthusiasts seeking a car with enhanced performance characteristics, the Mercedes-AMG’s model line-up is certainly one of the first that worth considering. The German brand integrates a lot of advanced performance-oriented features in its models, and some of these cars come with an unusual sports transmission named as AMG SpeedShift MCT. In this article we will consider the main design peculiarities of this unit, its modifications and principle of operation.
Go4trans.com has already highlighted some basic information on the 2020 Supra transmission swap project performed by EAG in one of our previous articles. This time we want to delve into the technical side of the project with the help of numerous videos provided by EAG and learn more about the company itself.
Many drivers know about the importance of ATF change, but, unfortunately, they frequently forget about filter replacement. In this article, we will learn why it is important to timely replace automatic transmission filters, examine their types, and become familiar with their replacement frequency.
Constantly accelerating pace and growing road traffic in cities often forces you to make hasty decisions when you are behind the wheel to reach the destination point in time, but in some cases it happens at the expense of the car’s operability. For instance, it has been widely debated on how it will affect the car equipped with the automatic transmission, if you shift your car from R to D gear while still moving backwards.
Among different types of car transmissions, CVTs are notable for not having gears at all. It uses a set of pulleys and belts to provide numerous ratios for a variety of driving situations. While it may seem like an ideal solution for some auto enthusiasts, as you won’t be bothering with gears driving this car, some car brands, such as Mazda, just disregard the CVT.
In automatically shifted cars an oil pan services as a so-called storage for ATF, and ensures for a convenient access point to the transmission filter and fluid. For automatic transmissions (ATs) ATF is vitally important, as it lubricates transmission parts and prevents overheating, thereby avoiding early wear of the transmission unit.
Continuously Variable Transmissions (CVTs) have been around for quite a long time, but for some drivers this type of transmission still remains a mystery. CVT transmissions have certain design peculiarities, which have a significant impact on rules of operation of these units. In this article, we will consider the main aspects of driving CVT-equipped cars and learn how to avoid early visits to repair shops.
The main differences between these two units lie in the fact that the 2WD output shaft is longer than the 4WD version and 4WDs are connected to a transfer case. Some carmakers manufacture their 2WD transmissions in such a way that they can be transformed into 4WD models.
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.
Automatic transmissions function with the help of hydraulic pressure to implement the process of gear shifting itself, and utilize valve body solenoids to handle the pressure of the ATF to specify the shifting points. There are many solenoids responsible for different gear shifting operations, and in this article we will have a closer look at downshifting solenoids.
