Here's why:
* Automatic transmissions: Automatic transmissions are not designed for towing. The transmission fluid circulates through the system, relying on the engine to pump it. When towed, the transmission isn't moving, and the fluid can overheat, damaging the transmission.
* Chevy Sonic: The 2012 Chevy Sonic's manual states that it is not designed for flat towing.
To tow a 2012 Chevy Sonic, you'll need to use a tow dolly, which supports the rear wheels, or a car hauler, which carries the entire vehicle.
