Flat towing, also known as “four-down towing,” is a popular method for transporting vehicles behind an RV or truck․ It offers convenience and eliminates the need for a trailer․ However, not all vehicles are designed for flat towing․ Many modern cars with automatic transmissions require an auxiliary transmission pump to protect the transmission during towing․ This article delves into the intricacies of these pumps and their importance in safe flat towing․
Why Do Some Cars Need Auxiliary Transmission Pumps?
Automatic transmissions rely on a fluid-based system to engage and disengage gears․ When a vehicle is flat towed, the transmission isn’t moving, and the fluid isn’t circulating properly․ This can lead to overheating and damage to the transmission․ Auxiliary transmission pumps address this issue by providing a constant flow of transmission fluid, even while the engine is off․ They typically work by drawing power from the tow vehicle’s battery and circulating the fluid, preventing overheating and wear․
Types of Auxiliary Transmission Pumps
Auxiliary transmission pumps come in various forms and can be installed in different ways․ Here are some common types⁚
- External Pumps⁚ These are separate units mounted on the vehicle’s frame and connected to the transmission cooler lines․ They are typically easier to install and maintain․
- Integrated Pumps⁚ These are integrated into the transmission itself, often as a part of the transmission cooler․ They offer a more streamlined installation but may be more difficult to access for maintenance․
- Electric Pumps⁚ These pumps rely on electric power to circulate the fluid․ They are common in modern vehicles with electronic transmission control systems․
- Hydraulic Pumps⁚ These pumps use hydraulic pressure to circulate the fluid․ They are typically found in older vehicles with mechanical transmission control systems․
Benefits of Using an Auxiliary Transmission Pump
Using an auxiliary transmission pump for flat towing offers several advantages⁚
- Protects the transmission⁚ Prevents overheating and wear by ensuring proper fluid circulation․
- Extends transmission life⁚ Minimizes the risk of transmission failure, allowing for worry-free towing․
- Improves towing safety⁚ Reduces the likelihood of transmission malfunctions that could lead to accidents․
- Peace of mind⁚ Provides confidence that your vehicle is being towed safely and securely․
Choosing the Right Auxiliary Transmission Pump
Selecting the right auxiliary transmission pump is crucial for safe flat towing․ Consider the following factors⁚
- Vehicle compatibility⁚ Ensure the pump is designed for your specific vehicle model and transmission․
- Installation ease⁚ Choose a pump that is easy to install and access for maintenance․
- Reliability⁚ Opt for a pump from a reputable manufacturer with a proven track record․
- Price⁚ Balance cost with the benefits of the pump’s features and reliability․
Conclusion
Auxiliary transmission pumps are essential for safe and responsible flat towing of cars with automatic transmissions․ They prevent overheating and wear, ensuring the longevity of your vehicle’s transmission․ Understanding the different types of pumps and their benefits can help you make an informed decision when choosing the right one for your specific towing needs․ Remember, investing in a quality auxiliary transmission pump is an investment in the safety and reliability of your towed vehicle․
