For RV enthusiasts who tow their vehicles behind their motorhomes, finding a car with a flat-towable automatic transmission is essential. Flat towing, also known as “four-down towing,” allows you to tow your car with all four wheels on the ground, eliminating the need for a trailer. This method offers convenience, fuel efficiency, and less wear and tear on your towed vehicle.
However, not all automatic transmissions are designed for flat towing. Conventional automatic transmissions, when towed with the engine off, can damage the transmission due to the lack of lubrication and internal pressure. This is where “flat-towable” transmissions come into play.
What Makes a Transmission Flat-Towable?
Flat-towable automatic transmissions are specially designed to handle the stresses of being towed with the engine off. They feature⁚
- Lubricated Components⁚ These transmissions have internal components that are lubricated even when the engine is not running, preventing damage from dry operation.
- Neutral Safety Switch⁚ This switch disconnects the transmission from the drivetrain when the car is in neutral, preventing damage to the gears.
- Transmission Cooler⁚ A dedicated transmission cooler ensures adequate cooling of the transmission fluid during towing.
Popular Cars with Flat-Towable Automatic Transmissions
Several car manufacturers offer models with flat-towable automatic transmissions. Some popular options include⁚
Jeep
- Jeep Wrangler⁚ The Wrangler’s optional Command-Trac NV241 transfer case is flat-towable when engaged in neutral.
- Jeep Cherokee⁚ The Cherokee’s optional Selec-Trac II transfer case is also flat-towable when engaged in neutral.
Chevrolet
- Chevrolet Silverado⁚ The Silverado’s 8-speed automatic transmission with the 4WD system can be flat-towed with the transfer case in neutral.
Ford
- Ford Escape⁚ The Escape with the 4WD system and the optional “Tow Ready” package can be flat-towed.
Important Considerations
Before flat towing any car, consult your owner’s manual for specific instructions and limitations. It’s also crucial to⁚
- Engage the Parking Brake⁚ Ensure the parking brake is engaged to prevent the vehicle from rolling.
- Use a Tow Bar⁚ Utilize a high-quality tow bar designed for flat towing.
- Check Fluid Levels⁚ Regularly check transmission fluid levels and add fluid as necessary.
- Maintain Proper Tire Inflation⁚ Inflate tires to the manufacturer’s recommended pressure for towing.
Flat towing a car with a compatible automatic transmission can greatly enhance your RVing experience. By carefully following the manufacturer’s guidelines and taking necessary precautions, you can ensure a safe and enjoyable towing experience.
