No, it is generally not okay to tow an automatic car with its driven wheels on the ground, even if the transmission is in neutral. This practice can lead to severe and costly damage to the vehicle's transmission system.
Why Towing an Automatic Car in Neutral Can Be Harmful
Towing an automatic car with its driven wheels on the ground, even in neutral, causes the drive shaft to turn. This, in turn, spins the internal components of the transmission. The critical issue is that an automatic transmission relies on the engine being on to properly circulate lubricating fluid (transmission fluid). When the engine is off and the car is being towed, these internal parts are spinning without adequate lubrication and cooling.
This lack of proper lubrication leads to:
- Excessive Heat Buildup: Friction from unlubricated or poorly lubricated parts generates extreme heat.
- Component Wear: Gears, bearings, and other vital transmission components experience rapid wear and tear.
- Fluid Degradation: The remaining transmission fluid can overheat and break down, losing its protective properties.
Risks of Improper Towing
Improper towing methods for automatic transmission vehicles can result in significant mechanical failures, leading to expensive repairs or even a complete transmission replacement.
- Overheating: The primary risk is the transmission overheating due to insufficient lubrication and cooling, causing internal damage.
- Component Damage: Gears, clutches, bands, and bearings within the transmission can seize, warp, or wear out prematurely.
- Fluid Contamination: Overheated fluid can carbonize, creating sludge and varnish that further clog and damage the transmission.
- Voided Warranty: Using an incorrect towing method may void your vehicle's warranty.
Proper Towing Methods for Automatic Cars
To prevent damage, automatic cars require specific towing methods that ensure the driven wheels are not in contact with the ground.
