Knowing your transmission weight is helpful if you plan to lift, load, move, or deliver it.
Most transmissions weigh between 100 and 400 pounds (45 to 181 kg), with the average falling around 226 pounds (103 kg).
Automatics are often heavier than manual transmissions due to their increased complexity.
In the following sections, you'll learn the transmission weights of various models.
Rebuilding a transmission.
What Is the Average Weight of a Transmission?
The average transmission weight ranges from 100 to 400 pounds (45 to 181 kg), with most standard-size transmissions weighing roughly 226 pounds (103 kg).
However, transmissions come in a variety of types, sizes, and weights based on their design and performance.
So, the above isn't a one-size-fits-all measurement.
How Heavy is a Manual Transmission?
The weight of manual transmissions varies massively depending on the car, but it's typically somewhere between 100 and 400 pounds.
For example, the transmission in a small-ish front-wheel drive car, like a Honda Civic, could be lifted single-handedly and thus weighs around the 100-pound mark.
How Much Does a CVT Transmission Weigh?
A CVT — Continuously Variable Transmission — is a single-speed automatic gearbox used in various vehicles.
Usually, you'll find them in cars, tractors, snowmobiles, motor scooters, and even earthmoving equipment.
Due to its compact size and simple construction, it's lighter than standard automatic transmissions, increasing fuel efficiency.
Here are two examples so you can see how the weight of CVT transmissions can differ:
- The JF011E CVT found in the Nissan Juke weighs 150 pounds.
- The Honda D-series transmission sits within the 70- to the 90-pound mark.

How Much Does a Truck Transmission Weigh?
The weight of a truck's transmission depends on the truck itself.
They can weigh anywhere from 100 pounds to 400 pounds.
For example, a Chevy Silverado's transmission weighs 133 pounds without fluid, but a Dodge Ram's 545RFE transmission weighs 238 pounds with the fluid and converter.
How Heavy Is a Semi-Truck Transmission?
Semi-truck transmissions tend to fall on the heavier end of the 100 pounds to 400 pounds weight scale.
Usually, these vehicles come with a manual transmission so the driver can more easily control the torque in relation to the vehicle's velocity when carrying loads.
That said, semi-trucks with automatic transmissions aren't uncommon and are becoming more common by the year as they're much easier to drive.
How Much Does a V6 Transmission Weigh?
On average, a V6 transmission weighs between 100 pounds and 400 pounds or 45 kg and 181 kg.
Most standard-size V6 transmissions weigh in at 226 pounds or 103 kg.
Are Automatic Transmissions Heavier than Manual?
There's usually only a 50- to 75-pound difference between the weights.
Typically, manual transmissions are lighter than automatic versions with the same gear ratios and torque capabilities.
Automatic transmissions suffer worse fuel economy and drive train loss due to their heavier build.
The main culprit for the weight difference is the cast iron case enveloping automatic transmissions — this one distinction accounts for between 20 and 30 pounds.
Different hardware components also add weight.
Manual models have fewer parts than automatic transmissions, so the system and its housing are lighter.
Thankfully, heavier transmissions don't affect performance, meaning you should choose the type you prefer.
A transmission full of transmission fluid is heavier than a dry transmission.
Transmission Weights
Now we've covered the basics, let's explore the weights of specific transmission models.
How Much Does a Gm Transmission Weigh?
GM (General Motors), the innovator of automatic transmissions, boasts a wide product range, each with its own weight.
The company constructed the lightweight Roto Hydramatic, Model 5, which weighed just 145 pounds or 66 kg.
