Every car owner knows that quality transmission or gear fluid is crucial for maintaining the performance of your vehicle. But using a heavy-duty transmission fluid is a must if you are towing frequently.
Towing puts an insane amount of pressure on the car’s transmission system. Therefore, if you don’t use a transmission fluid that can handle such pressure, your vehicle can face serious performance issues and even end up in an entire engine failure.
There are over 20 variations of transmission oil in the market. On top of that, different vehicle manufacturers require distinct features of fluid in their automobiles. So, how do you choose the best transmission fluid for towing from the endless options?
Don’t worry. We’ve picked out the top transmission liquid for towing and described their most promising features in this article. You’ll also get to know everything you need to keep in mind while choosing the right gear oil for your towing vehicle.
What Type Transmission Fluids Are Best for Towing
Towing heavy cargoes such as trailers, boats, and other commercial loads overstress the vehicle’s drivetrain system, especially the transmission. This stress diminishes the lubricating effects of the transmission oil which results in increased friction and growing temperature.
Therefore, the best oil for towing would be one that provides high lubricating protection even at elevated temperatures. Synthetic transmission fluids are best known for holding onto lubricating properties and preventing thermal breakdown.
As towing puts additional stress on the system, synthetic fluids featuring anti-wear technology are great for protecting your transmission from premature wear.
Moreover, gear oils that include heat transfer additives will be helpful. Because increased temperature is the main cause of transmission damage.

How to Choose The Best Transmission Fluid for Towing?
While different vehicles call for different transmission fluids, there are some primary factors you must keep in mind before choosing one. To help you, we have discussed those principal aspects here.
Keep reading to find out everything you need to know to choose the best gear oil for towing.
Compatibility is the most significant thing to consider because using the wrong fluid can result in transmission failure.
Always make sure to check your vehicle’s manufacturer’s recommendation for transmission fluid. It’s important since some cars call for specific brands’ fluid.
However, some transmission oils have universal compatibility. These are great if you have multiple vehicles and don’t want to buy separate oil for each one.
2. Mineral Or Synthetic
Synthetic transmission oils possess higher heat withstanding capability. Therefore, you can use them at high temperatures for a longer period without losing the lubricating effects. And this is crucial for towing vehicles as they produce extreme heat.
However, synthetic oils are more expensive than mineral ones. Mineral oils do break down faster in high temperatures but they are pretty inexpensive. Also, many older vehicles do not support synthetic transmission fluid.
Hence, if you are on a budget or you’re driving an older car, mineral oils might be more suitable for you.
Protective additives are what enable the transmission to fight corrosion, foaming, and oxidation. As towing vehicles face these problems on a larger scale, having additives in the transmission fluid is a must.
High-quality fluids often come with anti-oxidation and anti-foaming additives. These prevent oil breakdown and protect your transmission system for longer.
Yes, the weather you’ll be driving in is also something to consider while choosing a transmission fluid. Because some fluids break down faster in extreme heat others lose working capability in cold weather.
If you want to experience optimum performance in all weather conditions, choose a transmission fluid that has the all-weather withstanding capability.
However, if you live in an extremely cold or hot climate, go for one that suits your area’s weather best.
Question: Why Should I Change Transmission Oil?
Answer: Like other engine oils, transmission oil breaks down with usage and loses its lubricating property. If you don’t change the oil when required, your transmission system will face increased friction and temperature. Therefore, you should change transmission oil to keep the transmission system running smoothly.
Question: What Are The Symptoms Of Low Transmission Fluid?
Answer: You can check the level of transmission fluid using the dipstick. But when your transmission is low on fluid you may notice one or more of the following symptoms: grinding or whining noise, leaking fluid, burning smell, and slipping gears.
Question: How Often Should I Change The Transmission Fluid?
Answer: Check the manufacturer’s guidelines to find out the exact time interval of changing the fluid. In general, you need to change the transmission oil after driving 30,000 to 60,000 miles. But in towing vehicles, you’ll need to change the oil more frequently.
Question: Should I Perform Transmission Fluid Flush Or Change?
Answer: This depends on the condition of your vehicle and the outcome you expect. Transmission fluid flush is recommended if your vehicle has been running on the same fluid for more than 70,000 miles or if you want to start using a new type of ATF.
But if your cars on good condition and you only require regular maintenance, transmission fluid change is fine.
Question: What Is The Maximum Temperature Transmission Fluid Can Handle While Towing?
Answer: You should not run the transmission at higher than 210 degrees. The transmission fluid will lose its lubricating features and break down after 260 degrees.
Choosing the right transmission fluid is critical for towing vehicles. Because using wrong or substandard fluids can cause transmission failure and lead to disastrous consequences on the road.
We understand how confusing it can be to choose the most suitable fluid from hundreds of different variants available in the market right now.
