Can Cars with CVT Transmissions Be Flat Towed?
Flat towing a vehicle involves towing it behind another vehicle with all four wheels on the ground. While this is a common and convenient way to transport vehicles, it is not suitable for all vehicles. In particular, vehicles with continuously variable transmissions (CVTs) may experience damage if flat towed.
Understanding CVTs
CVTs are a type of automatic transmission that uses a system of pulleys and belts to vary the gear ratio. This allows for smooth and efficient gear changes, making CVTs ideal for a wide range of vehicles. However, CVTs require lubrication from the transmission fluid to function properly.
Lubrication Issues
When a CVT vehicle is flat towed, the transmission fluid is not able to circulate properly. This can lead to a loss of lubrication and subsequent damage to the CVT components. Specifically, the following problems may occur:
* Overheating: Without proper lubrication, the CVT’s metal components can overheat and wear down prematurely.
* Bearing failure: The bearings that support the CVT’s components can fail due to lack of lubrication.
* Belt damage: The CVT’s belt can become damaged or stretched due to overheating or excessive friction.
Exceptions and Special Cases
While most CVTs are not suitable for flat towing, there are a few exceptions:
* Neutral position: Some CVT vehicles have a neutral position that allows the transmission to be disengaged during flat towing. This ensures that the CVT components are not damaged.
* Specific vehicle makes/models: Certain vehicle manufacturers have designed some CVT vehicles to be flat-towable. These vehicles typically have specific instructions and limitations regarding flat towing.
Manufacturer Recommendations
It is always recommended to consult the vehicle’s owner’s manual or manufacturer’s website for specific instructions on flat towing. Most manufacturers explicitly prohibit flat towing CVT vehicles due to the potential for damage.
Alternative Towing Methods
If flat towing is not an option for your CVT vehicle, you can consider the following alternative towing methods:
* Trailer: This is the most common and safe method for towing vehicles with CVTs. The vehicle is loaded onto a trailer, and the transmission is put in neutral.
* Dolly: A dolly is a trailer that only supports the front or rear wheels of the towed vehicle. This method can be used for CVT vehicles with a neutral position.
* Auto transport: Professional auto transport companies can transport your vehicle without the need for flat towing. This is a more expensive option, but it ensures the safety of your vehicle.
Conclusion
Flat towing CVT vehicles is generally not recommended due to lubrication issues and potential damage to the transmission components. While there are some exceptions, it is crucial to consult the manufacturer’s instructions to determine if your specific vehicle is suitable for flat towing. If flat towing is not an option, consider alternative towing methods to protect your CVT vehicle.
