Automatic transmission is currently installed on a large number of cars, but drivers are divided in their opinions about it. Some agree that it is extremely convenient, others say that it is more trouble than good. In particular, the claims relate to very expensive repair rates, because certainly, just as any other engineered element, it sometimes fails.

Nowadays, there is still no ideal solutions on how to transmit torque from the engine to the drive wheels — actually, there’s not even a universal agreement on the best location for the switching mechanism that controls the ratio changes.

Not always bubbles on transmission dipstick are caused by insufficient ATF (transmission oil) level or its overflow. Problem can be more serious. As a rule, this symptom indicates certain faults in the transmission operation. In most cases, transmission fluid foaming is caused by abnormal ATF levels, but sometimes it is a result of transmission being damaged badly.

Much like modern automotive trend on shifting from with manual transmissions to more confortable automatics, in the first decade of the last century there was a demand for a semi-automatic transmission that operated without the driver involvement. And automotive engineers of that time had some interesting engineering solutions to offer.

Automatic transmissions reduce the number of cars transmission components, which reduces automatic transmission and transferring engine power to the drivetrain. To improve shifts, one should reduce higher engine speed when torque increases and maintain an optimum RPM. Revolutions per minute (RPMs) are a measure of how quickly your transmission is transferring power from the engine to the wheels.

The advantage to just changing your transmission fluid over a transmission flush is that changing is much faster and will also be much cheaper. Flushing your transmission fluid is a better, more thorough alternative to a basic change, which, of course, means Flushing will also cost you more.

A manual transmission is a house of various components like gears, shafts, and various selecting mechanism that are arranged in a special fashion to provide appropriate torque and speed ratios to compete with the challenges provided by the different road conditions.

When considering a car purchase, reliable automatic transmission is a huge deciding factor. CVT transmissions are considered the most efficient and reliable type of automatic gearbox. Is it true?

An automatic transmission uses planetary gearing, also known as planet gears, to change the output speed and torque of a vehicle. A gear system consists of a central sun gear, a set of planet gears and an outer ring gear.

A fluid coupling allows the driver to use the clutch and gears with less skill and fatigue than with an all mechanical linkage, and transmits power from one shaft to another using fluid.

The most common type of automatic transmission is the Automatic Torque Converter (ATC), which uses a converter friction clutch and a clutch transmission to control the engine speed. It is similar to a manual transmission but uses a torque converter instead of a clutch.

If you notice one or more of the signs above, your transmission may be failing and needs to be repaired. - Engine related problems like a torque converter failure, automatic transmission whistles, and other unusual noises can indicate a major repair is needed.

Automatic gearboxes were first introduced in luxury vehicles in 1940, and eventually became available for mass-market cars in 1950. The first experimental hydromechanical transmission was developed in 1904 by the American engineer, Alfred Horner Munro.

This article discusses the differences between automatic and manual transmissions, and how each operates. A clutch is used in an automatic transmission, but it is operated differently than in a manual transmission.

In the last couple of articles, we used terminology relating to pressure control solenoids such as PWM, Frequency, and Duty Cycle. In this article I thought I would go into depth on what these terms really mean and how they relate to
