Understanding Transmissions and Transmission Repair

One of the most important parts of any vehicle is the transmission. The transmission is so important that the car would have evolved in a very different way without it. Due to it being so important, it is a big pain and a big cost when it needs to be fixed. So, here is what you need to know about transmissions and transmissions repair.

The transmission responds to the unique characteristics of the internal combustion engine. Most engines operate at a range of 600 to 7,000 revolutions per minute, but the wheels of the car only turn between 0 and 1,800 revolutions per minute. How the transmission comes into play is when the torque of the vehicle needs to be adjusted.

The highest torque output of the transmission can be found in the middle, around the third gear, but the greatest torque of the transmission comes when the vehicle is moving slowly. The transmission system has to take the output of the engine and supply high torque for low speeds, and to keep the engine within operational limits while at highway speeds. Put simply transmissions transform energy from the engine to the wheels.

Almost all transmissions use a cast-iron case or aluminum case that rests under the car. Within the transmission, there are three different kinds of shafts. The main shaft, the countershaft, and the idler shaft. The main shaft extends outside the case in both directions, the input shaft goes towards the engine and the output shaft goes towards the rear axle.

Main bearings suspend the main shaft and it splits near the input end. Pilot bearings hold the shafts together at this point. There are three types of transmissions found in cars, trucks, and other automobiles. The manual, automatic, and semi-automatic. Now to the part we all hate, transmission repair.

Typically when a transmission needs to be repaired, it is due to a shaft coming apart, bearings breaking off or even the entire transmission falling out of the car. This can happen and it has happened plenty of times since the car was first created. No matter what kind of transmission repair you may have to do, you are going to be paying a lot.

You can get a lower cost for transmission repair if you are lucky enough to find a working transmission for your make and model of a car at a local scrap dealer.
