The Nuance of Towing Automatic Transmissions
It’s a question that often sparks debate among car owners and travellers alike: 'Can you tow an automatic car?' The short answer is yes, but it comes with significant caveats. Unlike manual transmissions, which are generally more robust for towing in neutral, automatic gearboxes present unique challenges because they rely on internal lubrication systems that often require the engine to be running to function correctly. If the engine isn't running, the transmission's internal components may not receive adequate lubrication, leading to excessive wear or even catastrophic failure, especially over longer distances or at higher speeds.
The critical factor boils down to the specific design of the automatic transmission within your vehicle. Manufacturers engineer these systems with varying tolerances and lubrication methods. Some automatic transmissions are designed to withstand towing when specific conditions are met, while others are fundamentally incapable of being towed without incurring damage. This is why consulting your vehicle's owner's manual is not just a recommendation; it's an absolute necessity. It will clearly state the manufacturer's position on towing your specific model and outline any necessary preparations or limitations.
When we talk about towing an automatic car, we're usually referring to a few common scenarios: towing it behind a motorhome (often called 'recreational towing' or 'dinghy towing'), using a tow dolly, or placing it entirely on a car transporter trailer. Each method has its own implications for the automatic transmission. For instance, flat towing an automatic car (all four wheels on the ground, connected by a tow bar) is often the most problematic, as it usually requires the engine to be running or specific internal disengagement procedures to be followed. Towing with a dolly (lifting the front wheels) or on a trailer (all wheels off the ground) generally mitigates direct drivetrain stress, but specific vehicle considerations still apply.
Understanding Transmission Lubrication When Towing
The heart of the issue lies in how an automatic transmission is lubricated. Most automatic transmissions use the vehicle's own engine oil, pumped throughout the system as the engine runs. When the engine is off, and the vehicle is being towed, the pump doesn't operate. If the drive wheels (and therefore the transmission's output shaft) are turning, internal components can grind against each other without sufficient oil. This friction generates heat and causes wear. Imagine trying to run a complex piece of machinery without its essential lubrication – that’s precisely what can happen to your automatic gearbox if towed incorrectly.
However, not all automatic transmissions behave the same way. Some modern transmissions, particularly those with specific designs or advanced electronic controls, might allow for towing in neutral under certain conditions. This could involve placing the gear selector in Park, then shifting the gear lever to a specific 'neutral' position, or disengaging an internal component. Other vehicles might require the engine to be started periodically to circulate the transmission fluid. Your owner's manual is the only authoritative source for this crucial information, detailing procedures like setting the gear selector to neutral, disabling the starter motor, or even specific disconnects for the driveshaft on older models.
Failing to respect these requirements can lead to costly repairs. A transmission that seizes or overheats during towing might require a complete rebuild or replacement, a bill that can run into thousands of pounds. This makes understanding the 'why' behind the restrictions paramount. It’s not just about following rules; it’s about safeguarding a complex and expensive piece of automotive engineering.

Methods of Towing an Automatic Car
So, if you've confirmed that your automatic car is indeed towable according to its manual, what are the actual methods you might employ? The choice often depends on your towing vehicle, the distance, and your budget, but the primary concern remains protecting that automatic gearbox.
Flat Towing (All Four Wheels Down)
This is often the most convenient method, as it requires less equipment. You simply attach a tow bar to the towed vehicle and connect it to your motorhome or larger vehicle. However, for automatic transmissions, this is frequently the riskiest approach. Many automatic cars cannot be flat-towed with the engine off because the drivetrain will be under load and the transmission won't be lubricated. Some manufacturers specify that the engine must be running and the transmission in neutral during flat towing. This means you'd need a way to keep the engine idling safely, which itself can present challenges like battery drain or overheating if not managed correctly. Others might have a specific procedure, like shifting into a 'neutral' position or disengaging the driveshaft. Always check your manual – if it says 'do not flat tow' or provides extremely strict conditions, heed that warning. It’s also worth checking for recalls like the Stellantis engine fire recall, which, while not directly related to towing, highlights the importance of manufacturer advisories on vehicle systems.
Towing with a Dolly (Front or Rear Wheels Lifted)
A tow dolly is a small, two-wheeled trailer that lifts either the front or rear wheels of the towed vehicle off the ground. If you're towing an automatic car with a dolly, you'll typically lift the drive wheels. For front-wheel-drive cars with automatic transmissions, this means the front wheels are lifted, so the transmission isn't turning. For rear-wheel-drive cars, you'd lift the rear wheels. This method often bypasses the need to run the engine, as the transmission is not actively engaged or being turned by the wheels touching the ground. However, always verify that lifting the non-drive wheels is appropriate for your car's braking system and steering. If the steering wheel locks, it can cause issues, and some vehicles have specific requirements about disabling steering or immobilisation systems.
Using a Full Car Transporter Trailer
This is generally the safest and most recommended method for towing any vehicle, especially one with an automatic transmission, if you have any doubts. A car transporter trailer physically carries the entire vehicle, with all four wheels off the ground. The towed car's drivetrain is completely disconnected from the road surface, meaning the transmission isn't being turned. This method avoids the lubrication issues entirely. The main considerations here are the weight and size of the trailer, the towing capacity of your vehicle, and the logistics of loading and securing the car onto the trailer. It requires more effort and space but offers peace of mind that no damage will occur to the transmission.
Regardless of the method, it’s crucial to understand how your car's systems interact. For example, if you’re using a dolly or trailer and the car's battery is needed for braking or lighting systems, ensure it's adequately charged or has a dedicated power source. For manual cars, you might consider how to bump start a manual car if the battery dies, but for automatics, the focus is on preventing drivetrain damage first and foremost.
Potential Risks and How to Mitigate Them
The allure of towing your automatic car, whether for a holiday or a move, is strong. However, the potential for damage means that vigilance and adherence to specific protocols are non-negotiable. Ignoring the manufacturer's guidance can lead to a cascade of problems, turning a planned journey into a costly nightmare.
Transmission Overheating and Wear
As discussed, the primary risk is the lack of lubrication and subsequent overheating of the automatic transmission. When towed incorrectly, internal components can grind, generating excessive heat. This heat can degrade the transmission fluid, reducing its effectiveness and leading to further wear. Over time, this can manifest as slipping gears, delayed engagement, or a complete failure to shift. In severe cases, components can seize, rendering the car undrivable and necessitating a full transmission rebuild or replacement, a repair that often costs thousands of pounds.
Tyre and Drivetrain Stress
Even when towing methods are seemingly safe, other issues can arise. For instance, if a car is towed with its steering wheel locked, the tyres can scrub and wear unevenly, potentially leading to premature tyre replacement or even tyre failure at speed. If you notice your car pulling to the left or right during normal driving, it suggests an alignment issue that could be exacerbated during towing. Ensure your tyres are in good condition and properly inflated. For those concerned about the general mechanics, understanding basic maintenance like wheel lug nut torque is always beneficial, though less directly related to towing itself.
Electrical System Issues
Modern cars have complex electrical systems. When towing, you might need to disable anti-theft systems, immobilisers, or specific safety features to prevent them from engaging while the car is being moved. If the vehicle battery is used for auxiliary functions or for the towed vehicle's braking system (common with larger trailers), ensuring it’s fully charged and healthy is vital. A dead battery can lead to immobilisation or a loss of braking assistance, creating a dangerous situation. If you’re concerned about electrical systems, sometimes the issue might even relate to minor problems like condensation in car or how to stop condensation in car, but these are usually unrelated to towing damage itself.
Always perform a pre-towing check. Inspect all connection points, test the lights and brakes of the towed vehicle (if applicable), and double-check that all safety equipment is secure and functioning correctly. Never assume.
Mitigation Strategies
The best mitigation strategy is diligent research and careful execution. Read your owner's manual thoroughly – this is your primary guide. If the manual is unclear, contact the vehicle manufacturer's customer service directly. When flat towing, consider if your specific vehicle model has any known issues or specific procedures recommended beyond the standard manual guidance. For those who are still hesitant about the complexities of automatic transmissions, especially concerning towing, remember that sometimes the most prudent course of action is to opt for a full car transporter trailer, removing the guesswork and potential for damage entirely.
The peace of mind offered by correct towing procedures is worth far more than the cost of potential transmission repairs.
If the transmission does seem to act up after towing, stop immediately and have it checked. Early detection of issues like a small leak or unusual noises can prevent a minor problem from becoming a major breakdown. It might even be worth considering how an alloy wheel repair cost compares to the potential cost of a transmission rebuild before you start if you’re using the car for frequent long-distance towing.
When in Doubt, Leave It to the Professionals
You've read the manual, you've weighed the options, and perhaps you're still feeling a pang of uncertainty. Can you tow an automatic car? Yes, but the complexity and the potential for costly mistakes mean that sometimes, the most sensible and 'complete' answer is to delegate the task. If you’re transporting a vehicle over a significant distance, or if your automatic car is particularly valuable or has a complex transmission system, using a professional vehicle transportation service is often the best recourse.
Why Professional Transport is a Smart Choice
Professional vehicle transporters have the right equipment – specialised trailers, ramps, winches, and securement systems – designed to handle a wide variety of vehicles safely. They understand the nuances of different drivetrain types, including automatic transmissions, and are insured for any damage that might occur during transit. This removes the guesswork and the risk from your shoulders. You don’t have to worry about whether you’ve followed the correct procedure for your specific model, how to manage the engine running, or whether the steering will lock. The professionals handle it all, ensuring your vehicle arrives at its destination without any mechanical issues arising from the transport itself.
Comparing Professional Services
When looking for a professional service, several factors are important. Get quotes from multiple reputable companies. Ask about their experience with automatic transmissions specifically. Enquire about their insurance coverage and what happens in the unlikely event of damage. Check reviews from previous customers. While this method is an added cost, it is often considerably less than the potential cost of repairing or replacing a damaged automatic transmission. It’s a trade-off between immediate cost and long-term mechanical integrity.
Always verify the identity and credentials of any towing or transport service. Never pay the full amount upfront and ensure you have a clear contract outlining the service provided and liability.
Ultimately, the decision on whether to tow your automatic car yourself or hire a professional hinges on your confidence, your vehicle's specific requirements, and your risk tolerance. For those embarking on long journeys or unfamiliar with the intricacies of their vehicle’s drivetrain, professional transport offers a clear, safe, and stress-free solution, ensuring your automatic car reaches its destination in the same condition it left.
