When it comes to the transmission system of your vehicle, there are a few key components that you should be familiar with. Two of thee components are the flexplate and flywheel. While they may seem similar, they are actually quite different and are used in different types of transmissions.
Let’s start with the flywheel. This component is typically found in vehicles equipped with manual transmissions. The flywheel is a round metal disc that is attached to the engine’s crankshaft. Its purpose is to store rotational energy and provide a smooth and consistent surface for the clutch to engage with. The flywheel also helps to balance the engine’s rotating assembly to reduce vibrations and improve overall performance.
Now, let’s move on to the flexplate. This component is used in vehicles with automatic transmissions. Similar to the flywheel, the flexplate is also a round metal disc that is attached to the engine’s crankshaft. However, instead of a clutch, the flexplate has a ring gear that is used to engage with the starter motor. The flexplate also serves as a mounting location for the torque converter. This means that the flexplate transmits engine torque to the torque converter housing.
So, why are there two different components for manual and automatic transmissions? The answer lies in the way that each type of transmission operates. Manual transmissions require a clutch pedal to be depressed in order to disengage the engine from the transmission. This is where the flywheel comes in, as it provides a surface for the clutch to engage with. Automatic transmissions, on the other hand, use a torque converter to transmit power from the engine to the transmission. The flexplate is designed to work with the torque converter and help transmit engine torque to the transmission.
The flywheel and flexplate are two important components of a vehicle’s transmission system. While they may seem similar, they are actually quite different and are used in different types of transmissions. If your vehicle has a manual transmission, you will need a flywheel. If your vehicle has an automatic transmission, you will need a flexplate. Understanding the differences between these two components can help you make informed decisions when it comes to maintaining and repairing your vehicle’s transmission system.
Differences Between Flywheel and Flexplate
Flywheel and flexplate are both used to connect the engine to the transmission, but there are some significant differences between the two. A flywheel is typically used in vehicles with manual transmissions, while a flexplate is used in automatic transmissions.
A flywheel is a disc-shaped component that is bolted to the end of the crankshaft of an engine. It is designed to store rotational energy and povide a smooth, consistent surface for the clutch to engage with. The clutch disc is mounted between the flywheel and the pressure plate, which is bolted to the flywheel. The flywheel’s primary function is to keep the engine running smoothly and provide a consistent rotational force to the transmission.
On the other hand, a flexplate is similar to a flywheel in many ways, but it is used in vehicles with automatic transmissions. The flexplate is bolted to the end of the crankshaft and provides the same function as the flywheel, but it also has a ring gear around the outer perimeter. This ring gear is used to engage with the starter motor, which is used to start the engine.
Another key difference between the two is the weight. Flywheels are typically heavier than flexplates because they need to store more energy to provide a consistent rotational force to the transmission. In contrast, flexplates are lighter because they do not need to store as much energy since the torque converter in an automatic transmission can provide additional torque to the transmission.
The main difference between a flywheel and a flexplate is the type of transmission they are used with, as well as their weight and design.

The Difference Between a Flex Plate and a Flywheel
A flex plate is similar to a flywheel in terms of its function, but they are not the same component. A flywheel is typically found in vehicles with manual transmissions, while a flex plate is used in vehicles with automatic transmissions.
Both components are designed to transfer power from the engine to the transmission, but they do so in slightly different ways. A flywheel is a heavier, solid disc that is bolted directly to the engine’s crankshaft. It stores energy and helps to smooth out the engine’s power output.
On the oher hand, a flex plate is thinner and more flexible, which allows it to absorb vibrations and shocks from the engine as it runs. It is bolted to the torque converter, which connects the transmission to the engine.
While a flex plate and a flywheel serve similar purposes, they are not the same component and are designed for different types of transmissions.
Using Flywheel Instead of Flexplate
In general, it is not recommended to use a flywheel instead of a flexplate or vice versa. The reason for this is that these two components serve different functions and are designed specifically for the type of transmission in your vehicle.
A flywheel is typically used in vehicles with a manual transmission and is responsible for poviding a mounting location for the clutch assembly, which engages and disengages the engine’s power to the transmission. Additionally, the flywheel stores rotational energy to help the engine maintain a consistent idle speed and smooth out any fluctuations in engine power delivery.
On the other hand, a flexplate is typically used in vehicles with an automatic transmission and serves as a mounting location for the torque converter. The torque converter is responsible for transmitting power from the engine to the transmission, and the flexplate is what connects the torque converter to the engine.
While there may be some rare cases where a flywheel could be adapted to work with an automatic transmission or a flexplate could be used in a manual transmission, it is generally not recommended. Using the wrong component could cause issues with the transmission or engine, and could potentially lead to safety issues while driving. It is always best to use the component that is designed specifically for your vehicle’s transmission type.
The Purpose of a Flex Plate
The flexplate, also known as the flywheel, is a critical component of an engine’s torque transmission system. Its primary purpose is to connect the engine’s crankshaft to the torque converter, wich is responsible for transferring power to the transmission. The flexplate is designed to absorb the engine’s torque and rotational energy, as well as to provide a mounting surface for the torque converter. Without a flexplate, the engine’s torque could not be transmitted to the transmission, which would result in the vehicle’s inability to move. Additionally, the flexplate also helps to balance the engine’s rotational forces, reducing vibrations and improving overall engine smoothness. the flexplate plays a crucial role in ensuring that the engine’s power is efficiently transferred to the transmission, allowing the vehicle to operate smoothly and efficiently.
Causes of Flexplate Failure
A flexplate is an essential component of an automatic transmission system that connects the engine to the torque converter. It is a thin, circular metal plate that helps to transfer the engine’s power to the transmission. However, a flexplate can fail due to various reasons.
One of the most common cases of flexplate failure is an out of balance engine or torque converter. When the engine or torque converter is not balanced correctly, it can cause vibrations that can damage the flexplate over time. These vibrations can cause the flexplate to crack or break, leading to a catastrophic failure.
Another cause of flexplate failure is a bad starter drive. The starter drive is responsible for engaging the ring gear on the flexplate to start the engine. If the starter drive is worn out or damaged, it can cause the teeth on the flexplate or ring gear to wear rapidly or break off. This can result in a grinding noise when starting the engine or cause the engine to fail to start altogether.
Lastly, the teeth on the flexplate can break when the engine is running and the starter is engaged. This can happen if the starter is engaged while the engine is already running, causing the flexplate to twist and break. This can also happen if the starter motor is too powerful, causing excessive torque on the flexplate teeth, resulting in their failure.
A flexplate can fail due to an out of balance engine or torque converter, a bad starter drive, or the teeth on the flexplate breaking when the engine is running and the starter is engaged. Proper maintenance of the engine and transmission system can help to prevent flexplate failures and prolong the life of the flexplate.
Lifespan of a Flexplate
A flexplate is a critical component in a vehicle’s transmission system, and its lifespan largely depends on the quality of the material used, the driving style of the operator, and the overal maintenance of the vehicle. On average, a flexplate can last between 100,000 to 150,000 miles if it is not subjected to any undue stress, such as misalignment or excessive heat. However, if there is a misalignment issue with the engine or transmission, or if the flexplate is exposed to extreme heat, it can cause premature wear and tear, resulting in the flexplate breaking or failing. In such cases, a flexplate can break in as little as 15,000 to 30,000 miles. Hence, it is essential to ensure proper alignment and regular maintenance of the vehicle to maximize the lifespan of the flexplate.
What is the Origin of the Term ‘Flexplate’?
A flexplate is called so because of its unique ability to flex or bend across its main axis. This bending motion occurs as a result of the torque converter’s movement, which causes rotational speeds to change. The flexplate is a component of an automatic transmission system that is responsible for transmitting power from the engine to the transmission. It serves as a connection point betwen the engine’s crankshaft and the torque converter. As the engine rotates, the flexplate transmits the rotational energy to the torque converter, which then converts this energy into hydraulic pressure to drive the transmission. The flexplate’s ability to flex and adapt to the changing rotational speeds of the torque converter is key to its smooth operation and efficient power transfer. Therefore, the name “flexplate” accurately describes this component’s function and unique ability to flex as needed during operation.
Similarities Between Flexplate and Flywheel
The flexplate and flywheel are similar in that they both connect to the crankshaft of the engine and help transfer the rotational energy to the transmission. Both serve as a mounting surface for the clutch assembly or torque converter and are essential components in the operation of the engine and transmission. Additionally, manufacturers have made advancements in both components to optimize balance and reduce weight, with the addition of holes and grooves. While the flywheel is typically used in manual transmissions and the flexplate is used in automatic transmissions, they serve a similar purpose in the overall function of the drivetrain.
Consequences of a Broken Flexplate
When a flexplate breaks, it can cause serious damage to your vehicle and potentially put you in danger. The flexplate is an essential part of an automatic transmission system that connects the engine to the transmission. Its purpose is to transfer the engine’s power to the transmission, whih then sends that power to the wheels.
If the flexplate breaks, it can no longer transfer power from the engine to the transmission. This can cause a loss of power to the wheels, making your vehicle unable to move or move efficiently. Additionally, a broken flexplate can cause the transmission to become locked up, which can lead to further damage to the transmission and other parts of the vehicle.
In some cases, a broken flexplate can also cause the engine to stall or shut off completely. This can be especially dangerous if you are driving at high speeds or in heavy traffic. In extreme cases, a broken flexplate can cause the transmission to seize up completely, which can result in a loss of control of the vehicle and potentially cause an accident.
It’s important to have your flexplate regularly inspected and replaced if necessary to avoid these potentially dangerous situations. If you notice any warning signs of a bad flexplate, such as clunking or grinding noises from the rear of the engine, it’s important to have your vehicle inspected by a professional mechanic as soon as possible.
The Disadvantages of Using a Flywheel System
The main downside of using a flywheel system is its high cost, making it an expensive option for energy storage. Additionally, there is a risk of self-discharge, which means that the energy stored in the flywheel can dissipate over time, reducing its effectiveness. Flywheel systems are also only appropriate for smaller capacities, ranging from 3 kWh to 130 kWh, limiting their use for larger energy storage needs. Despite these drawbacks, flywheel systems have several advantages, including low maintenance costs, a long expected lifetime, fast response, and high roundtrip efficiency, making them a viable option for certain energy storage applications.
Can Flywheels Damage Transmissions?
A damaged or improperly installed flywheel can caue damage to the transmission. The flywheel is an essential part of the engine that helps to transfer power from the engine to the transmission. If the flywheel is not installed correctly, it can cause vibrations or misalignment that can damage the transmission over time. Additionally, a worn or damaged flywheel can cause the clutch to slip, which can also cause damage to the transmission. It is important to ensure that the flywheel is installed correctly and is in good condition to avoid any potential damage to the transmission. If you suspect that your flywheel may be causing issues, it is best to have it inspected by a professional mechanic to prevent any further damage.
Spinning a Flexplate by Hand
You can spin a flexplate by hand. The flexplate is the part that connects the engine to the transmission in an automatic transmission vehicle. It is located at the back of the engine and is attached to the crankshaft. The flexplate has teeth on the outer circumference that engage with the starter motor to crank the engine over.
To spin the flexplate by hand, you will frst need to remove any obstructions that are in the way. This may include the transmission, bell housing, and other components that are attached to the engine. Once the flexplate is exposed, you can use a pry bar or a screwdriver to turn it. Insert the pry bar or screwdriver into one of the teeth on the outer circumference of the flexplate and use it to turn the flexplate. You can also turn the flexplate by hand if you have enough clearance to reach it. Simply grab the outer edge of the flexplate and turn it in a clockwise or counterclockwise direction.
It is important to note that if the flexplate is difficult to turn or feels like it is binding, there may be an issue with the engine or transmission. In this case, it is best to have a professional mechanic inspect the vehicle to determine the cause of the problem.
Do Modern Engines Include a Flywheel?
Modern engines do have flywheels. The purpose of a flywheel is to store rotational energy and maintain the engine’s smooth operation by preserving the momentum from one combustion stroke to the next. However, modern engines are designed to be more efficient and lightweight, so the flywheels used in modern engines tend to be smaller and lighter than thse used in older engines. This helps to reduce the overall weight of the engine and improve its performance. Additionally, some modern engines may also use alternative technologies, such as dual-mass flywheels or flexplates, to achieve the same effect as a traditional flywheel.
Cost of Replacing a Flexplate
Replacing a flexplate can cost anywhere from around $50 to $160, depending on several factors such as the make and model of your vehicle, the type of flexplate required, and where you take your vehicle for repairs. The flexplate or flywheel plate is a critical component in your vehicle’s transmission system that connects the engine to the torque converter, allowing it to transfer power to the transmission. If the flexplate is damaged or worn out, it can caue serious problems such as vibrations, engine misfires, and difficulty shifting gears.
