How Much Does a Transmission Weigh? (With Examples)

Every vehicle is constructed with numerous components that contribute to its total weight. Among the heaviest of these parts are the engine, transmission, and chassis. Other components add a few pounds incrementally, culminating in a vehicle that can weigh 2 tons.

The transmission is one of the essential parts that keeps a vehicle moving. It determines how much power and torque will be sent to the wheels in certain driving conditions. There are different transmissions, manual and automatic being the most commonly used.

They also come in different weights depending on how they are built. If you have been curious to know the weight of these parts, you are in the right place. Here is a breakdown of various transmissions and how they operate.                

Average Weight of Transmissions

The weight of a vehicle’s transmission can determine how it works on your car. On average, vehicle transmissions weigh between 100 and 400 pounds. However, some vehicles use light transmissions to keep the weight minimum.

The engineering of the transmission and its functions form its basic units. This relates to the weight that transmits power from engines to wheels. While most transmissions conform to the 100 and 400-pound mark, there are special exceptions. Nonetheless, this weight range represents most standard vehicles.

You need to understand the weight of your transmission when working on your car or fixing the transmission. You can also consider the weight if you are buying new parts, putting it up for sale, or understanding your vehicle better.

The size and weight of your transmission increased with the size of your vehicle. Therefore, a smaller car will have a lighter transmission than a pickup truck or minivan.

9 Example Manual Transmission Weights

Automatic transmissions are very easy to use because they take all the shifting work from the driver. They automatically select gears for the user depending on the conditions and what should be done. Automatic transmissions are used in most high-performing vehicles.

The weight of automatic transmissions varies depending on the vehicle. They are heavier than manual transmissions because they are built from cast iron. They also have multiple internal parts for shifting gears, adding more weight to the end project.

Do Automatic Transmissions Weigh More Than Manual Transmissions?

VS

Automatic transmissions weigh more than manual transmissions, with a weight difference of between 50 and 75 pounds. Manual transmissions are lighter, and understanding the weight difference is great to guide you when buying a new car. Manual transmissions are lighter than automatic models with the same torque capabilities and gear ratios. This explains why automatic vehicles experience drivetrain loss and poor fuel economy.

Automatic models are heavier because of their build. They are enclosed in cast iron, while manual transmissions have aluminum casts. The construction alone accounts for a weight difference of 20-30 pounds. In addition, there are hardware differences that we must consider because automatic transmissions include more parts. The system and the casing must therefore be heavier and larger.
