Anyone who drives a car can die at any time if the transmission breaks down. It’s not something you would want to go through.

But what do you do if this important part of your car starts to break down?

Do you get a new one or fix the one you have?

Some people will buy a new one, while others will rebuild the transmission system. It all comes down to how much money someone has.

How do you rebuild it if you decide to?


Come with me as I show you how to rebuild your Transmission step by step.

But before we can do that, we need to know what the transmission system is.


What is Transmission?

Transmission is a system that is part of a car’s engine. The vehicle is the only one responsible for changing gears.

The energy from the engine is then sent to the wheels, which makes the car move.

In plain English,

It is the part that turns the power from the engine into a force. When that force gets to the wheels, it moves the car forward.

Transmission comes in two types.

The Transmission That Does Itself. It’s when the car changes gears on its own without the driver having to do anything. It means that the driver of the car does not change the gears.

The transmission by hand. It is where the gears of the car are changed by the driver. The transmission stick and the clutch pedal help make this happen.

Without the Transmission, the car can’t go from point A to point B. So, it is an important part of any kind of car.


What is the importance of a transmission to a vehicle?

The transmission is one of the most important parts of your car. So, it is a very important part of your car.


The transmission system is made up of different parts that all do important jobs. The following are some of these parts:

1. Transmission fluid

Transmission fluid is poured by hand through a funnel as part of good car maintenance.

Transmission fluid keeps the parts of the engine from getting too dry. The fluid makes sure that the transmission system works well.

Also, it helps keep the engine cool by keeping it from getting too hot. Also, the luid is thick. It is a way for the engine to send power to the transmission system.

2. Planetary gear set

It is a set of gears that help the car move by moving the most powerful turning force in a compact way.

3. Transmission Sensors

There are two kinds of sensors: those that measure speed and those that measure pressure.

The speed sensors tell us how fast the Transmission is going in and out. The same information is then sent to the transmission control unit (TCU).

The information helps control pressure and figure out which gear to use.

The pressure sensors figure out how much hydraulic pressure is on the parts of the transmission.

4. Torque converter

It is an important part of the car because it helps the car stop without the engine stopping all of a sudden.

It also helps start your car by giving it that extra push it needs to get going.

There are also other parts in the transmission system.

Bands and clutch pack.

Output axle and shaft.

All of these parts are very important to the transmission system.

Let’s go back to what I was talking about when I talked about how important the Transmission is.

It is important because it turns the force of the engine into power that moves the car. Without the transmission, your car’s engine power can’t get to the wheels.

To put it simply, the transmission system connects the engine to the wheels.

The RPM is something else you should know about. The RPM of the engine is higher (revolutions per minute). It usually goes faster than the wheels, which go between 700 and 7000 RPM.

So, it means that the wheels are going slower than the engine. Why? Because the engine turns much faster than the wheels.

The transmission system makes sure that the engine speed and the wheel speed are in sync.

The Transmission’s job is to turn both speed and momentum into power. In the same way, it gives the car the ability to use the power to move.

If you don’t take good care of the Transmission, it is likely to break down. It is very important to always keep in mind.

When it stops working, it can cost a lot of money to fix or rebuild.


How do you know that your Transmission Needs a Rebuild?

How To Rebuild A Transmission-3

There are some signs that your transmission system needs to be fixed.

When you press the gas pedal, the engine makes a loud, annoying sound. You will know right then that the transmission is broken and needs to be rebuilt.

While the car is moving, you will smell something burning or strange coming from the engine.

Another clear sign is that the transmission fluid is leaking.

When you leave your car in one spot for a while, coloured fluids start to show up on the ground. It means that something is wrong with the transmission system. Remember that there are different colours of transmission fluid. This makes it stand out from other oils.

Another sign is that the gears are grinding, which makes it hard to shift. It could be because the transmission fluid is dirty or the car is too hot, which makes the gears grind.

When you turn the gear, it either stays in one gear or doesn’t turn at all. It should tell you that you need a rebuild on your transmission system.

Even though the car’s engine is working fine, the car has very little or no power. It looks like the vehicle is having trouble getting going. It should tell you that the transmission is broken.

Transmission light signals are on most cars. When this light comes on, you should check your transmission.

When you see any of these signs, you need to check your transmission system. Then you can decide if you need to rebuild the system or replace the whole thing.

You might be curious about why some people say “rebuild” and others say “overhaul.” They have the same meaning.

More on that soon.


How do you Rebuild the Transmission?

As we’ve already talked about, the transmission is the most complicated part of a car.

Rebuilding the transmission isn’t as simple as changing a tyre. You need to know a few basic things about mechanics or cars.

You’ll find it easier to do the Transmission rebuild if you know what you’re doing and are good at it.

Come with me as I show you how to rebuild your Transmission step by step.

Before you start a rebuild, you must have the right transmission rebuild kit. You can buy or borrow the package. What kind of kit you need will depend on what kind of car you have.

What’s most important is that the transmission kit package has all the tools. If you are buying from a dealer, choose the one that has a full set of instructions.

Also, it’s important to note that the best transmission kit should include a warranty.

The second step is to take your car’s transmission out. To get to the Transmission, you will have to take the whole engine block off. You will also need to take off the torque converter and then the oil pan.

What’s the point of this second part?

Well, the Transmission is easy to get to if it is not attached to the car.

Many of the parts of the Transmission are almost the same. So, the worst thing you can do is take it off without paying attention to these parts.

If necessary, it’s important to label these parts.

After you’ve taken the Transmission out of the car, you can now take it apart. But before you do that, make sure all the transmission fluid is drained.

The third step is to clean and check all the parts of the transmission. After the second step above, the most important part comes next.

You look at it and figure out which part is broken. How do you do it? It involves cleaning these parts with a chemical that was made just for this job.

By doing all of this, you can find any worn out or broken parts that need to be replaced. Also, you clean the ones that are still in good shape and put them back in the Transmission.

Remember that it is important to get new oil seals and gaskets for everything.

It is important because it helps you stop any leaks that the old ones might cause or stop them from happening.

Putting the Transmission back together. It’s the part where you have to pay close attention to each piece. You must make sure that each part goes exactly where it should.

If you make even a small mistake, you’ll have to start over. Of course, this is why it helps to label these parts as you take them off.

You have to make sure that every part is exactly where it should be. The pressure test is then done, which is the last step.

The pressure test tells you if the pressure is too low, too high, or just right, and if it’s leaking or not. Don’t forget that pressure is important to the Transmission.

Because of this, you need to test and check the pressure.

The last step after that is to put the rebuilt transmission back on the car. If you have the right tools, it shouldn’t be hard.

Once you know what to do when rebuilding your Transmission,

How Long Should it Take you to Rebuild a Transmission?

As I said at the beginning, rebuilding a transmission is not a typical service job. Changing your engine oil or replacing a flat tyre is a simple task that even a beginner can do.

But that’s not all that’s needed to rebuild a transmission.

It is a hard job that requires a lot of knowledge. It has to be done by someone who knows how to do it.


How long it takes to rebuild the transmission depends on how hard the problem is to fix.

It will also depend on who does the rebuilding. If the person has never done it before, it will probably take longer than it should.

But if the person is an experienced mechanic, it shouldn’t take longer than expected.

Most of the time, it takes 3 to 4 days to rebuild a transmission. It will depend on where you took the Transmission to get it fixed up.

It’s smart to deal with your transmission problem as soon as you can. It cuts down on the amount of time it takes to rebuild the transmission and saves you money.

So, it will take you a long time to rebuild your Transmission if you don’t fix these small problems. Don’t forget about the stress and strain it will put on your wallet.

Rebuilding a transmission is part of the above steps. But you should ask yourself the following question.

How Much Will it Cost me to Rebuild a Transmission?

How to answer this question will depend on a few things. One is what kind and model of car you are driving.

If your car is very expensive, the cost of rebuilding the Transmission will also be more.

In the same way, repairing the transmission of a cheap car will cost less money.

How much damage has been done? How bad is the damage to the parts of the transmission? So, the cost of a rebuild goes up the more damage there is to the transmission parts.

So, if I take it to a garage or other shop to fix it up, it will cost me close to $3000. When you take into account the cost of labour and other things that technicians will do, it is true.

But if I do it myself, the cost will be cut in half. That’s between $1000 and $2000 USD. It means that if I take it to the garage, it will cost me more than if I do it myself.


In conclusion, rebuilding a transmission shouldn’t be too hard. It is a process that can only be done by someone with the right knowledge, skills, and tools.

If you know what to do, it will take less time and cost less money. Trust me. You’ll be glad you did.
