Many drivers enjoy the simplicity and reliability of an automatic transmission, but when it comes to racing, some enthusiasts believe that a manual is the only way to go. In this article, we’ll take a look at the pros and cons of both options so that you can make the best decision for your needs.

Rotating Mass

One of the most important aspects of racing with a Powerglide automatic transmission is managing the rotating mass in your car. The transmission itself is a relatively heavy component, and when you add in the weight of the torque converter, fluid, and other related parts, it can really add up.

There are a few things you can do to manage the rotating mass in your car:

– First, make sure that your transmission is properly serviced and maintained. A well-maintained transmission will spin more freely and with less resistance, which will save you precious horsepower.

– Second, consider using a lighter weight torque converter. There are many aftermarket converters available that are significantly lighter than stock units. This can really help to reduce the amount of rotating mass in your car.

– Finally, don’t forget about proper tire pressure. Making sure your tires are properly inflated will help to reduce rolling resistance and keep your car light on its feet.


Racing with a Powerglide automatic transmission can be a thrilling experience. But it’s important to understand the basics of how these transmissions work before you hit the track.

One of the key components of a racing transmission is the torque converter. This device uses fluid friction to transfer power from the engine to the transmission. The amount of fluid and the size of the torque converter determine how much power is transferred.

Friction is also used to engage and disengage the gears in an automatic transmission. When you put your foot on the brake, fluid pressure builds up in the system and engaging clutches are activated. This locks the gears in place so they don’t spin freely.

As you release the brake and begin to accelerate, the engaging clutches are released and gears begin to spin again. The spinning gears create fluid friction, which is used to rotate a turbine inside the transmission. This turbine is connected to a gear set that determines which gear you’re in (1st, 2nd, 3rd, etc.).

The amount of fluid friction created by the spinning gears also determines how fast you can go in each gear. The faster you go, the more fluid friction is created and this prevents damage to the transmission


As with any car, regular maintenance is important to keep your powerglide transmission in good working order. You should check the fluid level frequently and top it off as needed. If you notice any leaks, have them fixed immediately. It’s also a good idea to have the transmission serviced every 30,000 miles or so by a qualified mechanic.

The Powerglide Automatic Transmission

The Powerglide automatic transmission is a popular choice for racing applications. It is durable and can handle a lot of power. It is also relatively light and has a low drag coefficient. These characteristics make it ideal for use in racing cars.

There are two main types of Powerglide transmissions: the two-speed and the three-speed. The two-speed transmission is the more common type used in racing applications. It is simple and reliable. The three-speed transmission offers more gear ratios and is often used in drag racing applications.

When installing a Powerglide transmission in a racing car, it is important to choose the correct gear ratio for the application. A too-high gear ratio will result in excessive speed and wear on the transmission components. A too-low gear ratio will result in poor acceleration and performance.

It is also important to choose the right torque converter for your application. The torque converter helps to match the engine’s torque output to the transmission’s input shaft speed. A too-small converter will not be able to properly utilize the engine’s power and a too-large converter will cause the engine to rev too high.

How the Powerglide Automatic Transmission Works

The Powerglide automatic transmission is a two-speed automatic transmission that was used in General Motors vehicles from the 1950s to the 1970s. The Powerglide was designed to be a lightweight and simple transmission, and it was one of the first automatic transmissions to be used in mass-produced cars.

The Powerglide transmission has two gears: high and low. The high gear is used for normal driving, while the low gear is used for starting from a stop or when more power is needed (such as when going up a hill).

To change gears, the Powerglide uses a hydraulic system. When you step on the gas pedal, hydraulic fluid is sent to the transmission. This fluid pressure causes the transmission to shift into high gear. When you let off the gas pedal, the fluid pressure is released and the transmission shifts back into low gear.

The Powerglide transmission was used in a variety of GM vehicles, including Chevrolet, Pontiac, Oldsmobile, Buick, and Cadillac. It was also used in some non-GM vehicles, such as AMC’s Rambler American.

Despite its simplicity, the Powerglide transmission was reliable and durable. Many of these transmissions are

Pros and Cons of the Powerglide Automatic Transmission

The Powerglide automatic transmission was introduced in the 1950s and was widely used in racing vehicles of the time. The transmission gained a reputation for being tough and reliable, which made it a popular choice for many racers. However, there are some drawbacks to using a Powerglide transmission, and racers should be aware of these before choosing to use one in their vehicle.

One of the main advantages of the Powerglide transmission is its simplicity. The transmission has only two gears, which makes it much easier to maintain than a more complex transmission with more gears. This also makes the Powerglide transmission less likely to fail during a race. Another advantage of the Powerglide transmission is its strength. The transmission is built to withstand high levels of stress and can handle a lot of power.

However, there are some drawbacks to using a Powerglide transmission. One downside is that the transmission is not as efficient as some other types of transmissions. This means that your engine will have to work harder to move the vehicle, which can lead to increased fuel consumption. Additionally, the Powerglide transmission is not compatible with all types of engines. Some engines may not produce enough power to effectively use the Powerglide transmission

How to Use the Powerglide Automatic Transmission

The Powerglide automatic transmission is a great option for those who want to race their car. It is important to know how to use this transmission correctly in order to get the most out of it. Here are some tips on how to use the Powerglide automatic transmission:

1. Always use fresh, clean transmission fluid. This will help keep the transmission cooler and will also help prevent slippage.

2. When racing, avoid shifting into lower gears at high speeds. This can cause the transmission to overheat and can lead to failure.

3. Make sure that the transmission is in good working condition before racing. This includes checking the fluid level and making sure there are no leaks.

4. Use the proper shift pattern when racing with a Powerglide automatic transmission. Shifting too early or too late can cause problems and can lead to a loss of power.

5. Always let the transmission cool down after racing before shutting it off. This will help prevent damage to the transmission and will extend its life.

Racing With a Powerglide Automatic Transmission

Racing with a Powerglide automatic transmission can be a great way to improve your car’s performance. There are a few things you need to know before you get started, though.

First, you’ll need to find a transmission that’s compatible with your car. You can usually find this information in your car’s owner’s manual. Once you’ve found a compatible transmission, you’ll need to install it. This is usually a fairly simple process, but it’s always best to consult your mechanic to make sure everything is installed correctly.

Once your new transmission is installed, you’ll need to adjust your driving style to make the most of it. Powerglide transmissions are designed for high-performance driving, so you’ll need to rev the engine more often and shift gears more quickly than you would with a standard transmission.

With a little practice and patience, you should be able to master racing with a Powerglide transmission. Just remember to drive safe and have fun!


We hope you enjoyed reading about racing with a Powerglide automatic transmission. This type of transmission can be a great asset on the track, and with the right maintenance and care, it can last for many years.
