Automatic Transmission
Problems with an automatic transmission
The automatic transmission on the latest automobiles consist of a variety of components. These include: Planetary gear sets, the hydraulic system to control and activate the clutch, the torque converter which acts as a clutch allowing the vehicle to come to a standstill with engine running and in gear, the governor and throttle cable monitor that senses when to shift gears (in older models), and the onboard computer which senses various parameters allowing for precise gear shifting allowing you the freedom to choose between settings for high power or better mileage.

How all these components work is a very complex subject. The working of all of these components in perfect harmony requires high precision and split-second accuracy. The malfunctioning of even one component can cause undesired results during gear shifting. Smooth gear shifts happen when you can't hear it, but feel it when at the same acceleration your power suddenly drops down but speed increases. There is something wrong when you can feel the gear changing, but at the same time also hear a clinking sound. There is something really wrong when you feel a shudder with each gear shift.

RE: Automatic Transmission
To solve problem you need to know some of the terms and definitions associated it. To begin with, there is the Torque Converter. It is a mechanical and fluid coupling that connects the engine to the transmission.
