You can expect an average transmission weight to be about 100 to 400 pounds (45 to 181 kg) or about 226 lbs (103 kg) for a standard size transmission. Generally, the lighter a transmission is, the higher the performance is, although it depends on the vehicle.
Common uses to know transmission weight if you need to:
-
- Move it with a truck
- Lift it in a garage
- Load it into a vehicle
- Deliver it to a destination
Transmissions come in a range of different types and sizes ranging from light to heavy based on performance and design.

Automatic vs Manual Transmission Weight
When going through the manufacturer’s details, it’s important to take a careful look at the rating. This way, you make proper assessments based on what you need for your vehicle.
Automatic transmissions are typically heavier than manual or stick shift transmissions.
Manual or stick shift transmissions are typically lighter weight than automatic transmissions.
Why Do Transmissions Weigh So Much?
The main reason a transmission is so heavy is that it includes all the necessary gears for the engine to deliver power to the wheels. This is necessary in order to keep a transmission operational when in use. It helps to maintain a transmission’s power and a stable level of control in your vehicle.
To Conclude
Transmissions are quite heavy when it comes to auto equipment and parts. That’s why it’s so important to follow strict mechanic safety protocols while replacing or installing parts.
It’s important to know the correct weight when looking to transport your transmission. If you’re unsure and want specific weights, you can always check the manufacturer’s website.
