When it comes to transmission oil pans, there are two main options: deep transmission oil pans and bigger coolers. While both options have their benefits, there are some key differences to consider when deciding which is better for your vehicle. Deep transmission oil pans, such as those offered by aFe POWER, provide additional fluid capacity, which can help to dissipate heat more effectively and prolong the life of your transmission. They are constructed from durable cast aluminum and feature internal and external fins for maximum cooling. On the other hand, bigger coolers, like the ATS Deep Pans, focus on increasing fluid capacity to maintain lower temperatures, with the inclusion of a finned design and a magnetic drain plug. So, when deciding which is better, consider the specific needs of your vehicle and whether heat dissipation or increased fluid capacity is a higher priority.
What You'll Learn
Deep transmission pans may not cool the oil but can make it take longer to heat up
Deep transmission pans may not cool the oil, but they can make it take longer to heat up. This is because they increase the fluid capacity of the transmission, which means it takes longer for the oil to reach its operating temperature. However, once the oil does reach its operating temperature, it will also take longer to cool down.
Some people believe that a larger oil capacity can help lower transmission temperatures. However, this is not necessarily true because the amount of fluid passing through the transmission cooler over time remains the same. Therefore, a larger oil capacity may not provide any lower transmission temperatures.
Additionally, the air around the transmission pan is often hotter than the ATF, which means that the pan will not effectively cool the transmission fluid. In fact, it may even transfer heat from the outside into the ATF. As such, a larger transmission pan may not be an effective way to cool the transmission fluid.
Instead, a better way to cool the transmission fluid may be to use a larger transmission cooler. A larger cooler will actually increase the cooling capacity of the transmission, whereas a larger pan will not. This is because a larger cooler will have more surface area to dissipate heat, while a larger pan will not significantly increase the surface area for heat dissipation.
Furthermore, a larger cooler will be more effective at cooling the transmission fluid when the vehicle is moving slowly or idling, as it will still have airflow passing over it. In contrast, a larger pan will not benefit from this airflow and will rely solely on convection to dissipate heat.
In conclusion, while a deep transmission pan may make it take longer for the oil to heat up, it will not necessarily lower the operating temperature of the transmission. Instead, a larger transmission cooler may be a more effective way to lower transmission temperatures.

A bigger cooler may be better at cooling the oil
A larger cooler provides more surface area for heat exchange, allowing for more efficient cooling of the oil. This is particularly beneficial when towing heavy loads or during slow traffic when airflow over the transmission cooler is reduced. Additionally, a bigger cooler can help maintain lower oil temperatures over extended periods, reducing the risk of overheating.
Some users have reported significant reductions in transmission temperatures by upgrading to a larger cooler. For example, one user with a Dodge 5.9L Cummins engine reported a decrease in transmission temperatures from the low to mid-160s down to the 120s after installing a larger cooler. Another user with a Ford Super Duty noted that their transmission temperatures dropped from 225 to around 140-160 by adding a larger cooler.
It is important to note that simply increasing the size of the cooler may not always be the best solution. The effectiveness of a cooler also depends on other factors such as airflow and the temperature difference between the air and the oil. Mounting the cooler in an area with sufficient airflow is crucial for optimal cooling performance. Additionally, the type of oil used can also impact the effectiveness of the cooler, as synthetic oils can generally withstand higher temperatures without degradation.
While a bigger cooler can enhance cooling performance, it is essential to strike a balance. Excessive cooling can lead to lower oil temperatures, which may not be ideal for maintaining proper lubrication and burning off condensation within the crankcase. Therefore, it is recommended to maintain oil temperatures within a specific range, typically between 180°F and 260°F, to ensure optimal engine performance and longevity.

A bigger cooler may be more effective at reducing transmission temps
Installing an additional cooler can help to prevent this. Although all vehicles with automatic transmission equipment have a cooler in their radiator, this may not be enough to cool the fluid properly. An external cooler can assist the transmission fluid in cooling the exterior of the radiator more efficiently. A bigger cooler will help increase the life of the transmission by preventing your radiator from overheating.
In addition, a larger cooler can hold the transmission fluid in better shape for extended periods. Replacing the transmission fluid on time will allow the transmission to run at an acceptable operating temperature and extend your fluid’s life by ensuring the fluid stays cool.

A bigger cooler may be a more cost-effective solution
On the other hand, a bigger cooler will actually add cooling capacity. It will help to extract heat from the transmission fluid, resulting in lower temperatures. This is especially beneficial if you are experiencing high transmission temperatures or doing a lot of towing. A larger cooler will also help to prolong the life of your transmission by keeping the fluid at optimal temperatures.
Furthermore, a bigger cooler may be more cost-effective than a deep transmission oil pan. The price of a bigger cooler can vary, but it is generally around $350. A deep transmission oil pan can cost upwards of $450. Therefore, if you are looking for a more affordable option, a bigger cooler may be the way to go.
Additionally, a bigger cooler can be easier to install than a deep transmission oil pan. A cooler can often be bolted into the stock position, while a pan may require more modifications. This can save you time and money on installation.
Overall, if you are looking for a cost-effective solution to reduce transmission temperatures and improve the performance of your vehicle, a bigger cooler may be the best option. It will provide better cooling capacity, prolong the life of your transmission, and may be more affordable and easier to install than a deep transmission oil pan.

A bigger cooler may be easier to install
When it comes to choosing between a deep transmission oil pan or a bigger cooler, a bigger cooler may be the easier option to install. While a deep transmission oil pan can add extra capacity and help with heat dissipation, it won't necessarily lead to lower transmission temperatures. This is because the amount of fluid passing through the transmission cooler over time remains the same, and the pan itself is not an effective heat sink.
On the other hand, a bigger cooler will actually increase the cooling capacity of your system. This is especially true if you opt for an auxiliary cooler with a fan, which can be extremely effective when dealing with slow traffic or when towing heavy loads.
In terms of installation, a bigger cooler can often be a more straightforward option. For example, the 6.0L transmission cooler for the Ford Super Duty trucks is a popular choice and is known to be a relatively simple upgrade. It mounts in the same way as the stock cooler and only requires some minor plumbing changes to accommodate the larger tubing.
Additionally, when it comes to maintenance, a bigger cooler may also be more convenient. With a deep transmission oil pan, you will have to deal with the challenge of changing a larger volume of fluid during service. This can make the process more time-consuming and messy.
Furthermore, cost can be a factor when considering the ease of installation. While both options can vary in price, deep transmission pans, especially those made from aluminium, can sometimes be significantly more expensive than a larger cooler.
Therefore, if you're looking for a more effective and potentially simpler solution to reducing transmission temperatures, a bigger cooler is likely the better choice.
