* Flatbed towing: This is the safest method for all vehicles, including those with automatic transmissions. The entire truck is lifted onto the flatbed, and its wheels don't touch the ground during towing. This is the recommended method for a 2003 Chevy pickup with an automatic transmission.
* Wheel-lift towing: This method lifts only the front or rear wheels off the ground. This can damage an automatic transmission because the drive shaft is still spinning, which circulates transmission fluid without the engine running to lubricate and cool it. This method is generally NOT recommended for vehicles with automatic transmissions, including your 2003 Chevy pickup.
In short: Yes, it *can* be towed, but *only safely* using a flatbed tow truck. Wheel-lift towing risks serious transmission damage. Always specify "flatbed towing" to the towing service.
