Jacking up a car is a common task for many car owners, whether it’s for changing a tire, performing maintenance, or simply getting a better look underneath. But when it comes to choosing the right jacking point, many people wonder if it’s safe to jack up a car by the transmission.
The short answer is⁚ No, it is generally not safe to jack up a car by the transmission.
Why is it unsafe?
Transmissions are complex and delicate components that are not designed to withstand the weight of a car. Jacking up a car by the transmission can lead to several problems, including⁚
- Damage to the transmission housing⁚ The transmission housing is made of thin metal and can easily be cracked or bent under pressure, leading to leaks and other problems.
- Damage to internal components⁚ The weight of the car can put stress on the internal gears, shafts, and other components of the transmission, leading to premature failure.
- Loss of stability⁚ The transmission is not a stable point to lift a car. The jack could slip, causing the car to fall and potentially causing serious injury.
Where should you jack up your car?
Your car’s owner’s manual will usually specify the recommended jacking points. These points are typically located on the frame or the body of the car, where the metal is thick and strong enough to support the weight of the car.
In general, it’s best to avoid jacking up your car on any component that is not specifically designed for this purpose.
Alternatives to jacking up by the transmission⁚
If you need to access the transmission, there are several alternatives to jacking up the car by the transmission⁚
- Use a jack stand⁚ Once the car is raised with a jack, place jack stands under the designated jacking points for added stability.
- Use a hydraulic lift⁚ If you have access to a garage or shop with a hydraulic lift, this is the safest and most convenient way to lift a car.
