What Type Oil Cooler For Jeep Wrangler Manual Transmission?

Jeep Wrangler is not just a name; it’s a sensation to all off-roaders and adventurers. Without any doubt, this has been one of the most reliable choices worldwide.  The best feature about the Jeep Wrangler is its ability to be modified in every way possible. However, while modifying your Wrangler, we often forget about the transmission cooler. 

The majority of transmission issues are caused by transmission overheating. Countless automotive troubles have been blamed on transmissions.  As a result, it’s critical to pay attention to your Jeep Wrangler manual transmission cooler for a pleasant driving experience.

So, today in this guide, we will discuss everything you need to know about the manual transmission cooler of Jeep Wrangler. Read below to learn more!

What Are The Different Types Of Transmission Coolers?

The most efficient technique to avoid overheating is to install a transmission cooler in your car. The transmission cooler is a secondary condenser in your car that is solely responsible for chilling the gearbox. Transmission coolers are classified into three categories.

1. Plate and Fin

To attain some amount of thermal efficiency, this cooler functions slightly differently. The transmission fluid is moved via the plate and fin’s vertical aluminum sheet sequence. 

Plate and fin coolers have the appearance of small radiators. Furthermore, the horizontal aluminum plates boost the transmission fluid’s surface-to-volume ratio. 

Every line of tiny plates forces fluid across them, cooling it quicker and much more efficiently. They are, however, a little on the pricey side.

2. Tube and Fin

The tube that threads across the transmission cooler and the turbulators that surround it identify the tube and fin cooler. This is the cheapest and most basic form of transmission cooler on the market and the most popular.

When it comes to cooling TF, the tube and fin transmission cooler are the least costly but not as effective as other types of coolers.

The fundamental concept is to have airflow over the fins, creating a heat sink effect. A component of the cooler is the turbulator. As it passes through the tubes, the turbulator agitates the transmission fluids.

3. Stacked Plate

Stacked plate coolers are a step above when it comes to cooling efficiency—the stacked plate cooler functions similarly to the plate and fin cooler. The quantity of airflow required is the primary difference between these two transmission coolers. 

They employ a tube to transport the transmission fluid within the cooler, and the fins serve as a route for the fluid as it goes through the cooler. Stacked plates are also popular due to their simplicity of assembly and disassembly.

They are the most efficient sort of transmission cooler, but they are also the costliest.

What Type Oil Cooler Required For Jeep Wrangler Manual Transmission?

Because manual gearboxes do not have a torque converter that is continually creating enormous amounts of heat, a moderately sized cooler will suffice; it does not need to be gigantic.

That being said, manual transmission like a manual Jeep Wrangler doesn’t really require you to use a transmission cooler for cooling the oil. However, if you still want to use a cooler, you should go for a small and compact type of coolers. You can either choose between Plate and Fin or Tube and Fin coolers.

What Problems May Encounter With The Manual Transmission Oil Cooler?

There are many problems that you may encounter with a failed transmission cooler.

1. Overheating Transmission

The transmission cooler’s sole purpose is to lower the temperature of the fluid flowing through the machine. When the cooler fails to function correctly, the fluid temperature goes up. 

One of the most evident failing transmission cooler symptoms is this. When the transmission fluid begins to heat up, you may notice a burning odor.

2. Leak in Transmission line

A leak is the most typical indicator of a faulty transmission cooler. Lines leading into and out of the cooler have the potential to fracture or burst. Whenever a line breaks, transmission fluid would be found on the floor around the source of the leak.

3. Weird Sound Coming from Car

Due to the leaking of the transmission lines, the amount of fuel will eventually decrease, and this can lead to weird sounds from cars. You will also have an uncomfortable driving experience.

If the moving gear is difficult, unusual sounds may accompany the difficulty. The transmission contains several moving elements that require the correct oil temperature. 

But, when the coolant oil gets reduced due to leakage, pieces may begin to grind together, resulting in odd noises.

4. Warning Light

Most cars, no matter manual or auto transmission, comes with a variety of warning system to ensure driver’s safety. If you notice, check the engine light on your dashboard warning, which means there can be a problem with the coolant. 

As when the temperature of the coolant rises very high due to faulty transmission oil, the warning light can pop up.

How To Maintain A Manual Transmission Oil Cooler?

If you wish to avoid transmission cooler issues on your manual transmission, then you need to do proper maintenance, which we will discuss below.

Regular servicing of the transmission cooler:

The transmission cooler is an essential element in keeping your engine cool and preventing it from overheating. So, to ensure that your cooling system is in good working order, maintain the transmission cooler on a regular basis. 

If your automobile is subjected to heavy workloads, we recommend maintaining it at least once every three months.

Avoid Downshift during low speed:

As manual transmissions operate differently from automatic transmissions, downshifting can impose a load on the transmission system when decreasing speed or abrupt pauses.

So, rather than downshifting, use your brakes to slow down and stop, as this will ensure a healthy life for your transmission system.

Changing Transmission fluid every 30,000 KM:

Changing the transmission fluid in your automobile is essential for efficient gearbox operation. Each car has a unique timeframe for replacing the transmission fluid. 

However, in general, you should change your transmission fluid every 30,000 kilometers or at minimum once every year.

But, the correct working duration of your transmission fluid is heavily dependent on the roads you drive on as well as the amount of pressure it is subjected to.

How Hard Is It To Drive A Manual Jeep Wrangler?

Driving a manual Jeep Wrangler is a difficult task. It might be difficult to drive an off-road vehicle for the first time, especially if you are unfamiliar with manual transmissions.

While driving a manual Jeep Wrangler, the most crucial consideration is reasonable control over the clutch. Your manual riding experience will be as smooth as butter if you can master the clutch.

Moreover, the more practice you do on the road, the more perfect you will become in riding a manual Jeep Wrangler and soon realize that you can shift the gears without even looking at it.

Is A Used Jeep Wrangler With A Manual Transmission Worth Buying?

So, if you’re considering purchasing a used Jeep Wrangler, is it really worth it? Jeep Wranglers with manual transmissions are far more dependable and less complex than those with automatic. 

Furthermore, they require relatively little equipment and do not have unique pieces such as torque converters or valve bodies. As a result, you won’t have to spend much on replacement components.

Thus because of their simplicity, manual Jeeps are easier to fix. So, yes, it is undoubtedly worthwhile to purchase a used manual Jeep Wrangler if the vehicle is in good functioning order and has no severe accident history.


The manual Jeep Wrangler is a really reliable off-roader for adventure lovers. Due to the simplicity of build, manual cars usually do not require any types of coolers. 

However, you can use a tube and fin or a plate and fin type of fluid cooler as a Jeep wrangler manual transmission cooler to boost engine performance. These types of coolers are more than efficient in cooling the transmission fluid in your Jeep.

No matter which type of transmission cooler you use, make sure to properly maintain your transmission system if you do not want to keep spending money to repair these components every now and then.
