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.



Nowadays Extroid CVTs are commonly known as “toroidal” due to the fact that the working surface of driving and driven discs in this transmission has the form of a torus. Extroid CVT is not a V-belt transmission, but a friction drive CVT.
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.
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.
