The weight of a car transmission varies dramatically, typically ranging from 75 to over 400 pounds (34 to 181 kg). The specific weight depends primarily on the transmission type, the vehicle's size, and its intended use. For a standard passenger car, an automatic transmission generally weighs between 150 and 250 pounds (68-113 kg), while a manual transmission is often lighter, averaging 100 to 200 pounds (45-90 kg).
The core reason for this wide range is the fundamental difference in design and complexity. Here’s a breakdown of average weights for common transmission types found in consumer vehicles:
| Transmission Type | Average Weight Range (lbs) | Average Weight Range (kg) | Common Applications |
|---|
| Manual Transmission | 100 - 200 lbs | 45 - 90 kg | Compact cars, performance vehicles, older models |
| Traditional Automatic | 150 - 250 lbs | 68 - 113 kg | Sedans, SUVs, light trucks |
| Continuously Variable (CVT) | 125 - 175 lbs | 57 - 79 kg | Many modern fuel-efficient cars, subcompacts |
| Dual-Clutch (DCT) | 175 - 250 lbs | 79 - 113 kg | Sporty models, high-performance European cars |
| Heavy-Duty Truck Automatic | 300 - 400+ lbs | 136 - 181+ kg | Full-size pickups, commercial trucks |
Beyond the type, the vehicle's size is a major factor. A transmission for a small hatchback like a Honda Fit will be significantly lighter than the 10-speed automatic in a Ford F-150. Performance vehicles often have heavier transmissions built to handle high torque loads. If you're planning a project like an engine swap or need to ship a transmission, it's crucial to look up the specific weight for your vehicle's make, model, and year. This information is often available in service manuals or from parts suppliers.
