GM has recently filed an application for a patent on a method for controlling the transmission of a car by using a prognostic road curvature feature, coming with a front-facing camera.

As many car manufacturers have started using a fuel saving technology (better known as stop/start systems) quite frequently, not all drivers are happy with their efficiency, and GM wants to tackle this problem in perspective. The American carmaker has recently took out a patent for a know-how that is supposed to utilize GPS integrated in the stop/start solution, making it much smarter when it is required to switching off the engine.

Many car manufacturers want to minimize possible interference in the software of their latest models. In this endeavor, we have to mention GM that has been promoting “unhackable” ECUs in some models for some time now. This technology makes it almost impossible to carry out any significant tuning changes, but it seems like GM wants to change that.

GM has presented a new transmission solution for high-horsepower builds during the SEMA 2019 exhibition. Company’s representatives say that the new 6-speed automatic unit named as SuperMatic 6L80E ensures an impressive performance/efficiency ratio when paired with Chevrolet Performance’s (CP) LS and LSX crate engines.

The media source GM Authority has gained access to curious data on the abovementioned judicial cases. According to these materials, the automaker may have been well informed about the problems connected to its 8L90 and 8L45 transmission units as far back as September of 2014.

The nationwide labor strike at GM’s factories and warehouses, triggered and supported by United Auto Workers (UAW), is extended into its 2-nd week, as the talks between the labor representative and the car manufacturer face serious contradictions, ranging from labor conditions for part-time workers to salaries for new employees.

The 8-speed GM automatic transmission has already caused a lot of troubles for the automaker because of some technical issues. In April 2019, transmission issues eventually led to the court action against GM, in which car owners complained about numerous transmission problems and demanded it to be eliminated. Now it seems like GM has found an efficient solution for issues related to the 8-speed unit.

GM has officially stopped production at Warren Transmission Operations plant in Warren, Michigan. At the end of last year, the American auto giant announced the plan to close 5 of its production facilities in the US, and the Michigan facility was one of them. The facility was specialized in production of 6-speed automatic transmissions for the Chevrolet Impala and Cadillac XTS.

Recently, GM has announced that 2 of its 2020 models, namely Chevrolet Express and GMC Savana, will receive some upgrades of their transmission systems. It is claimed that the 8-speed automatics installed in both vans will be equipped with a fresh torque converters and absorbing mechanism.

As new car models are equipped with more and more advanced electronics, carmakers find new ways to add more free space in the driver’s cabin. The new digital push-button gear shifting mechanism in the upgraded 2020 Acadia is a vivid example of this trend.

Recently, it has transpired that a lot of GM car owners are determined to take legal action against the American Auto Giant. The complainant party claims that car owners of several RWD Chevrolet, Cadillac and GMC models (2015 and 2019 model years) experienced shakes, jolts, and hard shifting when engaging a gear during speeding up or slowing down.

Allison Transmission has announced that its 10-speed automatic gearbox will be installed in the new Sierra heavy-duty truck. The truck will hit the market in the second half of 2019.

Numerous studies say that the share of the global autonomous vehicle market will increase by more than 10 times from 2019 to 2026. There’s one issue of the new technology that deserves special attention: the influence of autonomous cars on auto repair shops and car maintenance services. More specifically, how repair shops of the future will adopt if driverless cars are to become the mainstream.

Recently, Allison Transmission, the leading international producer of commercial duty automatic gearboxes, together with Chevrolet announced the availability of a ten-speed automatic gearbox in the new Chevrolet trucks. The 2020 Silverado HD model with the automatic gearbox will be officially presented in winter 2019.

Recently, it has been revealed that PSA Group reached an agreement with Aisin AW to manufacture the EAT6 gearbox in France. Until recently, this transmission was produced by Aisin and imported from Japan, but the growing popularity of automatic gearboxes spurred PSA into action.

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.

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.

ACDelco, the main supplier of original spare parts for GM, unveiled the release of aftermarkets’ VVT (variable valve timing) solenoids for cars produced by General Motors. New VVT solenoids upgraded by GM specialists now can operate twice as long as other competitive products.

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.

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.
