Cars with automatic transmission are gaining ground in the India. Hardly a few people had heard of automatic transmission in cars a few years ago. Unlike the West, the car drivers here were fond of manual transmission more and to meet their requirements the Indian car market here was full of cars with manual transmission [...]

The modern automatic transmission is by far, the most complicated mechanical component in today’s automobile. Automatic transmissions contain mechanical systems, hydraulic systems, electrical systems and computer controls, all working together in perfect harmony which goes virtually unnoticed until there is a problem. This article will help you understand the concepts behind what goes on inside [...]
Transmission fluid should be changed periodically. Your owner’s manual should give you the recommended intervals which could be anywhere from 15,000 miles to 100,000 miles. Most transmission experts recommend changing the fluid and filter every 25,000 miles. Few transmissions have drain plugs to drain the old fluid. In order to get the fluid out, the [...]
The Hydraulic system is a complex maze of passages and tubes that sends transmission fluid under pressure to all parts of the transmission and torque converter. The diagram at left is a simple one from a 3-speed automatic from the ’60s. The newer systems are much more complex and are combined with computerized electrical components. [...]
Automatic transmissions contain many gears in various combinations. In a manual transmission, gears slide along shafts as you move the shift lever from one position to another, engaging various sized gears as required in order to provide the correct gear ratio. In an automatic transmission, however, the gears are never physically moved and are always [...]
The modern automatic transmission consists of many components and systems that are designed to work together in a symphony of clever mechanical, hydraulic and electrical technology that has evolved over the years into what many mechanically inclined individuals consider to be an art form. We try to use simple, generic explanations where possible to describe [...]
The transmission is a device that is connected to the back of the engine and sends the power from the engine to the drive wheels. An automobile engine runs at its best at a certain RPM (Revolutions Per Minute) range and it is the transmission’s job to make sure that the power is delivered to [...]
