How Does a Car Transmission Work?

A car transmission is a metal box that contains the gears that transfer power from the engine to the wheels. The torque converter is what transfers the power from the engine to the transmission. The transmission then sends it to the differential, which is connected to the wheels. The transmission has two main parts: the gearbox and the clutch. The gearbox is what contains the gears that transfer power from the engine to the wheels. The clutch is what disengages the engine from the transmission so that the car can change gears.

There are two types of transmissions: manual and automatic. Manual transmissions have three pedals: the clutch, the brake, and the gas pedal. Automatic transmissions have two pedals: the brake and the gas pedal. The clutch is what allows the car to change gears. It is located between the engine and the transmission. The clutch disengages the engine from the transmission so that the car can change gears.

Causes of a Transmission Fluid Leak

Transmission fluid leaks are one of the most common problems car owners tend to face. Transmission fluid leaks can be very dangerous and can cause your car to break down. If you think you have a transmission fluid leak, it is important to take your car to an Indianapolis mechanic right away.

There are a few different ways that transmission fluid can leak. The most common way is through a hole in the transmission. Another way is when the seals around the transmission start to leak. Transmission fluid leaks can also happen when the gaskets or O-rings start to leak.

Signs of Transmission Fluid Leaks

If you notice a pool of fluid underneath your car, it is likely that you have a transmission fluid leak. Transmission fluid is typically red in color, so if you see a reddish fluid, it is most likely transmission fluid. Another way to tell if you have a transmission fluid leak is by checking the level of transmission fluid using the dip stick. If the fluid level is low, it is likely that there is a leak. Transmission fluid leaks can lead to serious problems if they are not fixed, so it is best to get them fixed as soon as possible.

Common Problems Related to a Failing Transmission

There are many signs and symptoms that indicate a faulty or defective transmission, from whining, clunking, humming to slipping gears, dragging clutch, grinding, shaking, and more. However, the most common and detectable indications that your transmission is failing include burning smells, gear slipping issues, fluid leaks, and an illuminated check engine light.

Burn Smells

Do you smell something burning when you drive your car? This could be the transmission fluid burning up, which also means your transmission is overheating. So, if this is happening to you, it is likely due to low transmission fluid levels or very dirty transmission fluid content.

Gear Problems

If your car is refusing to go into gear, slipping gears, or a combination of both, you can safely assume it has to do with the problem within your transmission. If your cars refusing to go into gear, the most common causes are low or thickened transmission fluid, or because your shift cables or clutch linkage needs readjusting.

Fluid Leaks

Your transmission fluid plays a vital role in the overall operation and safety of your vehicle. As mentioned earlier, if you transmission fluids are low, your car will begin to show signs of trouble. If you have a leak in your transmission, then it is not capable of maintaining the proper fluid levels required to properly lubricate the inner workings of your transmission and engine. So, if you notice puddles of liquid underneath your car after it’s been sitting for a while, it could be a transmission leak.

Illuminated Check Engine Light

You can think you are check engine light for a number of warnings. On the other hand, it can be quite frustrating trying to figure out why your check engine light is on since there are so many reasons it could be. But if your check engine light does come on, it could very well be your transmission. Be sure to take it into an automotive mechanic to have it diagnosed before any further damages done to your vehicle.

How to Detect Transmission Problems

Your transmission speaks up when it’s not feeling well. So when something is wrong, you will get the message. And since your transmission is among the most vital components in your vehicle, it is wise to listen. Fortunately, it is not as difficult as you think to diagnose basic transmission malfunctions on your own. Continue reading to learn how to detect transmission problems in your car or truck, and what to do if you discover an issue.

Loud or Strange Noises

When your car is being verbal, it is best to pay attention. Different sounds can mean different things. In gear, strange sounds generally indicate manageable problems, like low fluids and dirty filters. If your vehicle is noisy in neutral (whining, clunking, and humming), then you may have serious mechanical problems like a worn reverse idle gear or worn gear teeth and bearings. Mechanical problems are likely to require part replacements, so it is important to take your vehicle into a licensed mechanic if you hear sounds like this when your gears are in neutral.


Whenever you see fluid leaking from your vehicle, you have reason to be alarmed. And it is critical to give it attention as soon as you are aware of any leak. Detecting a transmission fluid leak is easy since transmission fluid is red, translucent, and sweet-smelling. If you see a suspicious liquid with these characteristics, then it’s probably transmission fluid. In most cases, transmission fluid leaks are a result of a more serious issue so it is necessary to bring your car into an auto repair shop for professional service. If you check on your transmission fluid, and it is dark or smells burnt, it is time replace it with fresh fluid.

Burning Smell

When you can smell burnt transmission fluid, which smells a little sweet, it is a sign of overheating. One of the common causes for this is low transmission fluid, but it can be caused by other issues too, such as dirty filters or leak. This problem requires professional service from a licensed mechanic.

Check Engine Light

When your check engine light illuminates, it can mean a long list of things. And this can be frustrating. You must look for other clues to give you an indication of why it came on. Sometimes a simple open gas cap is the cause, while other times it can indicate something more serious. In terms of your transmission, the check engine light might come on if your vehicle’s computer picks up on some irregularities in the engine. An auto repair shop has the proper diagnostic equipment to identify the reason for your check engine light lighting up.
