With the progress in transmission technologies, many carmakers started to use dual-clutch transmissions instead of standard solutions. One of these dual-clutch innovations (DCTs) is the Powershift transmission designed by Ford. In this article, we will consider the main features of this transmission, its design peculiarities, and typical repair issues.

The design of modern cars includes a large number of components and assemblies, which are filled with technical fluids and lubricants. During operation, these fluids heat up, in other words they increase in volume, thereby increasing the pressure inside the car components and internals. This pressure difference must be leveled out to prevent depressurization, fluid leaks, and damages of car elements. For this purpose, some car components are equipped with a special valve, known as the breather.

Nowadays, the world’s leading car manufacturers actively install pre-selective gearboxes (also known as DSG or robotic gearboxes) in their new car models.This type of transmission is considered to be an ideal substitute for traditional automatic transmissions and CVTs. In this article, we will review a bright DSG option – S-tronic.

It is important to understand that the off-road qualities of any car directly depend not only on the engine, but also on the implemented transmission drive system. In this article, we will consider Easy Select and Super Select drive systems installed in SUVs produced by Mitsubishi.

The DSG transmission combines in itself features of classic automatic (comfort of operation) and manual transmissions (fuel efficiency). Currently, there are several DSG transmission models available on the market, namely, DSG-6, DSG-7, and Audi S-tronic. In practice, DSG transmissions are quite problematic in terms of repair, especially DSG-7. Due to high repair costs for this transmission many drivers try to fix the DSG-7 gearbox independently. In this article, we will consider how to replace the clutch pack in the DSG-7 transmission.

Today, many manufacturers equip their cars with continuously variable transmissions (CVTs). This transmission solution provides smooth change of the gear ratio parameter. Thanks to this peculiarity, CVTs have high efficiency and ensure maximum comfort while driving.

Transmission repair specialists frequently have to deal with such an issue as the mixing up of engine coolant (antifreeze substance) with the automatic transmission fluid. It is a very serious problem which can lead to the transmission failure and highly-priced repair or even transmission replacement. In this article, we will consider causes of this problem and possible solutions.

Young drivers sometimes wonder whether it is possible to use the engine oil as a lubricant for transmission parts. This is due to the fact that modern engine oils are designed for heavy loads and also include a wide range of active chemical additives for operation under severe conditions. In this article we will address this question.

If a car driver decides to change the fluid inside the transmission or engine, then he needs a convenient and high-quality unit for extraction of old fluid, its transfer, and most importantly for pumping in the new transmission fluid inside the gearbox (or other car component). Thus, fluid syringes (also known as oil suction guns) became quite popular among car repair specialists and drivers.

If you independently perform complex repair operations on the transmission (which usually involve the transmission tear-down), you can face some difficulties at the stage of reassembly, namely, when it comes to connection of the gearbox to the engine. In the article, we will consider the question of how to attach manual as well as automatic gearboxes to the car engine.

Joint efforts of Opel and Luk engineers led to development of the automated Easytronic gearbox which combines advantages of manual and automatic transmissions. In this article, we will consider design peculiarities, operating modes, pros and cons, typical problems of the Easytronic transmission and tips on how to prolong its service life.

Some cars equipped with automatic transmissions have an operating mode named “overdrive” (or O/D) i.e. the highest gear. This mode can be considered as an analog of the 5-th gear in manual transmissions.

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.
