Understanding Transmissions

by | May 30, 2014 | Autos

Transmissions mean different things to different people. To some car owners, a transmission is another big, expensive piece of the car that can break and cost them a fortune to repair. To some car enthusiasts, a transmission is a powerful part of their car, another piece that can be tuned and perfected and used to make the vehicle faster or more powerful. No matter which end of the spectrum you fall on, there is no denying the importance of the transmission in the overall function of your car or truck.

The Function of a Transmission

A transmission takes the energy from the engine and uses it to turn the wheels of a vehicle. The various gears in a transmission allow the power of the engine to be translated to many different speeds, a greater range than would be possible with a direct link between the engine and the wheels.

Types of Transmissions

The first transmission type was the manual transmission, which involved having the driver push in a clutch pedal while manually shifting gears. The automatic transmission came along next to try to make things easier. The automatic eliminated the clutch, using a torque converter instead to automatically shift gears, allowing the driver to just put the vehicle in “drive” and go. A more recent development is the constantly variable transmission (CVT). The CVT allows smaller cars to go through infinite gear changes in a specified range, allowing for greatly improved fuel efficiency (although it lacks the torque required to push bigger vehicles). All three transmission types are still in use today.

Transmission Problems

Transmissions are intricate machines with many moving parts, so there are a host of things that can go wrong with them. Fluid leaks, stripped gears broken valves—any of these things could be cause for concern and repair. In some cases, a transmission will need to be rebuilt, meaning it is taken apart, inspected, and all of the worn or broken parts are replaced. Some signs that a transmission is in need of repair could be unusual noises (such as a grinding or whining noise), problems shifting (rough shifts, slipping, delays before shifting into gear), leaking fluid or dirty fluid with a burnt smell.

If you suspect that your transmission is having problems, it’s best to have it checked out by a professional. So visit Trannyman.net today.
