The judicial authorities of Australia placed the carmaker under the obligation to pay a $10 million penalty for an inappropriate investigation of complaints.

Auto racing is a motorsport involving the racing of automobiles for competition. A reliable and efficient transmission is an indispensible part of each racing car and a key success factor. Carefully adjusted and balanced transmissions allow racers to get a split second advantage over other competitors during acceleration or turning of corners that may be decisive at the finish.

Recently, representatives of Allison Transmissions have reported that the company’s automatic gearboxes are selected by Navistar International for its brand-new medium truck, the International MV Series. According to Navistar, Allison fully automatic gearboxes will be applied in the new truck as a standard solution with all engines.

Tiptronic is a trade name of the manual gear shifting function (mode), which is implemented in the automatic transmissions. In the world of the automobile industry the name Tiptronic is used to define automatic transmissions of a specific design and control method regardless of the actual developer and producer of the transmission.

Currently it seems that the whole automobile industry became obsessed with more and more sophisticated transmission solutions. So why more gears? The list of potential advantages of such solution includes smoother shifts, enhanced fuel efficiency, and improved performance characteristics, but it's not all that simple......

The valve body is a hydraulic “controller” (also called as a “transmission brain”) consisting of valves, solenoids, sensors batteries and attached to them are passages and channels, which guide the flow of ATF to various valves with the purpose to activate required clutch and shift the gear properly according to the driving situation.

Only few people know about transmission concepts which were popular 70-90 years ago. For men of today, these gearboxes may seem very unusual and weird, but even now some gearboxes that date back to those years are quite competitive in comparison with modern transmissions.

Over recent years engineers developed a lot of gear shifting solutions for different car brands, which may seem a bit unusual for oldtime drivers. In this article we will review the most peculiar gear stick technologies and provide video materials related to these technologies.

While manual gearboxes utilize the clutch to shift speeds, automatic transmissions make use of a sophisticated hydraulic system for shifting, and the transmission solenoid is especially important for this process.

ATF issues are considered to be the main reason of automatic transmission failure, therefore some drivers use ATF additives. Automatic transmission fluid (ATF) additive is a luquid with unique characteristics which is used for improvement of the automatic transmission performance and prolonging its service life.

This article contains the information about the most popular automatic transmissions. We will review the most common problems encountered in automatic transmissions, present the most reliable gearboxes and warn about troublesome transmission solutions. Moreover, descriptions of transmissions are supplemented by images and different videos containing some general information on transmissions and their components, typical problems and repair tips.

Nowadays numerous specialized tuning agencies and transmission services offer auto enthusiasts the opportunity to upgrade automatic transmissions. Such tuning operations may vary from reprogramming of transmission control algorithms to complete replacement of transmission parts. But it is important to point out that transmission tuning is a painstaking procedure which requires detailed analysis of desired changes and possible consequences of implementation of such transmission specialties.

GM developed the 1-st automatic transmission using hydraulic oil in the 1930’s, and unveiled the “Hydra-Matic” transmission in 1940. The original Hydra-Matic was a crucial innovation in the auto industry. It wasn’t the first automatic transmission, but it was the first one that actually produced expected results.

Probably every transmission repair specialist was keen on LEGO constructions or at least enjoyed making some minor things with their hands. Here's the game taken to a new level of creativity!

Recently Allison Transmission presented its first 9-speed fully automatic transmission for medium and heavy duty vehicles at the auto industry exhibition in the USA. It is said that this innovation will contribute to emissions reduction, enhance fuel economy and improve stop-start feature.

Pak Suzuki Motor Company Limited releases the automatic transmission option of Suzuki Cultus. This transmission is a manual one, but equipped with the automatic gear shift (AGS) unit responsible for automatic clutch depression.

The new transmission has up to 5 distinct gearshift and throttle programs.Kia released several upgrades for its 7-seat mid-size crossover Sorento. The main innovations related to the modification of 2018 consist of two new trim levels (GT-Line and GT-Line S) and a new automatic transmission.

The Mini plans to provide Hardtop and Convertible cars with a new 7-speed DCT transmission equipped with the electronically controllable shifting mechanism. Due to faster gear-shifting, this transmission will add a sport-like driving experience in comparison with regular type automatic transmissions.

TCI unveils the new 4x Four-Speed automatic gearbox range. These are based on well-known 4L80E or 700R4 gearboxes and can be adjusted for non-GM applications too.

The Toyota Camry has always been known among auto enthusiasts as a very reliable and durable car and high selling ratings prove this point. But Toyota engineers are not ready to rest and promise that the 2018 model will have significant upgrades mainly related to the transmission.
