How Much Does a Transmission Weigh

The weight of a transmission depends on the type and size. A manual transmission typically weighs between 75 to 150 pounds, while an automatic is heavier, ranging from 100 to 250 pounds. The heaviest transmissions can be up to 400 pounds or more.

The total weight includes the torque converter, bellhousing and other related components. Generally speaking, smaller engines require lighter transmissions than larger ones because they don’t need as much power output capability.

The weight of a transmission varies depending on its type and size, but it can generally range from approximately 75 to 250 pounds. Larger transmissions such as those used in larger trucks and SUVs tend to be heavier than smaller ones found in sedans or compact cars. Additionally, automatic transmissions are usually heavier than manual transmissions due to their added complexity and components.

Ultimately, the exact weight of your vehicle’s transmission will depend on the specific make and model you own.

Truck Transmission Weight

Truck transmissions can vary in weight depending on the type of transmission and model. Generally, manual transmissions weigh between 100-250 pounds while automatic transmissions weigh up to 500 pounds or more. The heavier weight of the automatic transmission is due to its additional components such as torque converters and pumps that are not found in manual transmissions.

Furthermore, heavy duty truck models tend to have larger and heavier transmissions than lighter duty trucks, making them even heavier.

How Much Does a 6-Speed Transmission Weight

A 6-Speed Transmission typically weighs between 75-150 pounds depending on the model, size and make. Manual transmissions are generally heavier than automatic ones due to their more complicated design and higher number of components. The weight is also impacted by the type of materials used in its making such as aluminum or steel.

How Much Does a 18 Speed Transmission Weight

The weight of a 18 speed transmission varies depending on the type and model. Generally, though, an 18 speed transmission for a semi-truck can weigh between 120 and 200 pounds. This weight does not include the gears or associated components that are necessary to make it work properly.

How Much Does a Manual Transmission Weigh

The weight of a manual transmission can vary greatly depending on the size and type. Generally, the weight of a manual transmission ranges from approximately 75 to 150 pounds (34-68 kg). Additionally, most transmissions weigh significantly more if they are mated with an associated bell housing or flywheel.

How Much Does F150 Transmission Weigh?

The Ford F-150 transmission weighs in at approximately 300 pounds depending on the type of transmission. The most common is an automatic, 4-speed which weighs just under 300 pounds. If you have a manual five speed, the weight of your transmission will be higher than that of an automatic due to its thicker components and extra gears.

Additionally, if you have a diesel engine, then your transmission can weigh slightly more than one with a gasoline engine because diesel engines require stronger transmissions to handle their heavier loads. All together, when taking into account all types of transmissions for this truck model, we can estimate that the average F-150 transmission will weigh between 290-310 lbs (130-140 kg).

How Much Does a Gm Transmission Weigh?

The exact weight of a GM transmission depends on the model, as different transmissions feature different designs and components. Generally speaking, however, most automatic 6-speed transmissions weigh between 150 and 200 pounds (68 to 91 kg). Manual 4-speed transmissions in comparison are usually lighter at around 100 to 140 pounds (45 to 64 kg).

However, these weights can vary depending on the particular make and model of vehicle they were built for. For example the heavier duty 4L60E transmission used in larger vehicles such as SUV’s or vans is typically over 200 lbs (91 kg), while some lightweight aluminum performance models may be closer to 130 lbs (59 kg). It’s best practice to consult with your local GM dealer or repair shop before attempting any repairs related to transmission removal.

How Much Does an 8 Speed Transmission Weigh?

An 8-speed transmission typically weighs anywhere from 40 to 70 pounds, depending on the type and size of the vehicle it is being installed in. The weight of an 8-speed transmission can vary significantly, with larger vehicles usually having heavier transmissions that are designed to handle more power. There are also a few high performance transmissions available on the market that weigh less than standard models due to their lighter construction materials and design.

If you’re looking for a lightweight option, there are some aftermarket aluminum or magnesium alloy cases available which reduce the overall weight by around 10 pounds compared to traditional steel cases. Ultimately, when shopping for an 8-speed transmission it’s important to consider both its power capacity as well as its total weight in order to make sure you get the best fit for your specific vehicle needs.

How Much Does a Semi Truck Transmission Weigh?

The weight of a semi truck transmission varies depending on the size and type of truck. Generally, manual transmissions weigh between 400-600 pounds while automatic transmissions are usually heavier at 600-800 pounds. In addition to the transmission itself, other factors such as the engine type, make and model of the vehicle will affect its overall weight.

The total weight of a medium or large class eight semi truck can range anywhere from 10,000 to nearly 30,000 lbs., making it one of the heaviest components in terms of freight hauling capacity. To ensure safe operation and performance capabilities for your commercial vehicle fleet, it is essential that you consider both the gross payload capacity as well as any additional cargo mass when selecting an appropriate transmission system for your application needs.


This blog post has provided a comprehensive look into the weight of various types of transmissions and their common components. As we have seen, transmission weights vary greatly depending on the type and size of vehicle they are installed in, as well as the materials used to build them. That being said, it is clear that transmissions can be quite heavy – ranging from around 100 lbs for smaller vehicles up to 400+ lbs for larger vehicles.

While there are many factors that play into the overall weight of a transmission, this article has shown us just how much those differences can make when it comes to shipping or repair costs.
