Transmission repairs

There are several problems that can be resolved with an adjustment (A simple adjustment is one that can be made without removing the transmission from the vehicle.) or minor repair. If a late model transmission (computer-controlled transmissions started becoming popular in the early ’90s) is not shifting properly, it is often the result of a computer [...]

Computer Controls , Governor, Vacuum Modulator, Throttle Cable

Computer Controls The computer uses sensors on the engine and  transmission to detect such things as throttle position, vehicle speed, engine speed, engine load, brake pedal position, etc. to control exact shift points as well as how soft or firm the shift should be.  Once the computer receives this information, it then sends signals to [...]

One-Way Clutch and Bands

One-Way Clutch A one-way clutch (also known as a “sprag” clutch) is a device that will allow a component such as ring gear to turn freely in one direction but not in the other. This effect is just like that of a bicycle, where the pedals will turn the wheel when pedaling forward, but will [...]

Planetary Gear Sets

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 [...]

What is a transmission?

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 [...]

AUTO INSURANCE’S DRIVER SEX AND AGE CLASSES

Classification of cars by type of driver uses sex and age to define three kinds of subclasses: young men, young women, and unisex adult. According to annual police reports, men’s accident involvement per 100 licensed drivers is about twice women’s in each age group. Strikingly inconsistent with this pattern, however, is the insurance switch from [...]

Angular momentum

What important to car speed is moment of inertia. Since automotive use circular shapes for lots of engine parts. Therefore angular momentum is vital element. Moment of inertia, with respect to rotation, is called angular momentum. Angular momentum is the force that has to be overcome to spin a circular component (e.g., a flywheel and [...]
