How Your Car Transmission Works

 

If you’ve ever wondered about how your car transmission works, you’re not alone. There are a number of different types and functions. In this article, we’ll take a look at the most common types, their repair, and how they function. This will help you better understand how your transmission works and why it’s important to have a mechanic inspect it regularly. If you have any questions, don’t hesitate to contact us.

Functions

The automotive transmission transforms force from the engine into usable power, even from a stopped position. This mechanism transfers engine power from high to low gears, through the clutch and gearbox, to the axles and wheels, where it rotates. The engine provides the force and power, but because the output is too variable to produce usable speed, the transmission acts as a mediator. Typical types of transmissions include manual and automatic.

The main gear in a vehicle is called the sun gear, which rotates at high speeds and the inner planetary gear, which remains stationary. Small friction clutches engage the gears, and bands hold them in place. The bands are operated by pins and valves. Pressurized transmission fluid engages the clutches. These components are critical to the functioning of the car transmission. Keeping the transmission in top shape is an essential part of keeping a car on the road.

Among its various functions, the transmission increases and distributes power from the engine to the driveshaft and the wheels. A lower gear ratio acts as a torque multiplier, and a higher gear ratio is best for accelerating and driving uphill. An automatic transmission can also be used by drivers who cannot use their hands to change gears. The vehicle should be equipped with transmission coolers, which prevent the burning of the transmission fluid.

Types

There are many types of car transmission, including manual, automatic, and dual-clutch transmissions. The most common types are manual and automatic, and are also commonly called “automatic.” In recent decades, automatic transmissions have become more common than manual transmissions. Regardless of type, there are advantages to both. Read on to learn more about these car transmissions. Listed below are some of the differences between the two types.

Automatic manual transmissions (AMTs) are an older version of automatic transmissions. They operate by either a gear-shifter or steering wheel paddles. Dual-clutch automatic transmissions (DCT or DSG) are more common, and are used on vehicles such as BMW and Audi. Porsche uses a variant called PDK (Performance Dynamic Dual Clutch) to control the speed and shift gears.

CVTs are easy to drive and are popular in many hybrid cars. Although they aren’t as fuel-efficient as automatic transmissions, they offer a smoother ride and better fuel economy. These transmissions are also popular among consumers, though some may find them strange at first because they don’t shift. However, some automakers offer CVTs with pre-programmed ratios so the driver can drive in the desired gears without having to change the gears. They also eliminate the need for a clutch pedal and have an auto-like gear shifter.

Repairs

Rebuilding a transmission can be a costly undertaking, but it can often save you money over a replacement. A transmission technician dismantles the transmission and thoroughly inspects each part. They may also replace worn or outdated parts and perform diagnostic tests on the transmission’s electrical system. Once the repairs are complete, the technician reassembles the transmission and installs it into the engine. Finally, they test it before returning the vehicle to the owner.

Some of the first signs that your car may need car transmission repairs are noises, vibrations, or erratic shifting. If you notice any of these symptoms, it’s time to take your vehicle to a mechanic for an inspection. Transmissions are vital to the smooth operation of a car, and if there’s a problem, you must address it immediately. Here are some symptoms to look out for:

Depending on the problem, car transmission repairs can cost anything from a light transmission repair to a complete replacement. The type of repair you need will depend on your symptoms and the make and model of your vehicle. If your transmission is malfunctioning, it will likely require a rebuild of the entire system, as automatic transmissions are more expensive to repair. Additionally, foreign-made vehicles will cost more to repair than domestic models. But, you can still expect to save money if you choose a minor repair.
