Why I Strongly Recommend GM 10L90 Transmission Cooler Upgrades

As a proud owner of a vehicle equipped with the GM 10L90 transmission, I cannot stress enough the importance of upgrading the transmission cooler. After experiencing firsthand the consequences of not having a proper cooling system in place, I have learned my lesson and would highly recommend others to make this upgrade as well.

First and foremost, the GM 10L90 transmission is known for its power and performance. Whether you have a muscle car or a heavy-duty truck, this transmission can handle it all. However, with great power comes great heat generation. The stock transmission cooler simply cannot keep up with the demands of this powerful transmission, leading to overheating and potential damage.

By upgrading to a larger and more efficient aftermarket cooler, you can ensure that your transmission stays within safe operating temperatures even under heavy load or extreme driving conditions. This not only prolongs the lifespan of your transmission but also improves its overall performance.

Moreover, investing in a high-quality aftermarket cooler can save you from costly repairs down the road. A damaged transmission due to overheating can result in thousands of dollars in repairs and replacements. By spending a fraction of that amount on an upgraded cooler now, you can avoid

My Buying Guide on ‘Gm 10L90 Transmission Cooler Upgrades’

As a car enthusiast and owner of a GM vehicle with a 10L90 transmission, I have come across the need for upgrading my transmission cooler. The factory-installed cooler may not always be sufficient in keeping the transmission at an optimal temperature, especially during heavy towing or high-performance driving. Upgrading to a better and more efficient transmission cooler can prevent damage to your transmission and prolong its lifespan. In this buying guide, I will share my knowledge and experience in choosing the right GM 10L90 transmission cooler upgrade.

Why Upgrade?

The GM 10L90 is a robust and capable transmission, but it can still benefit from a better cooling system. Heat is the number one enemy of transmissions as it can cause fluid breakdown, leading to premature wear and potential failure. The stock cooler may not be able to handle the heat generated during extreme driving conditions, resulting in overheating and potential damage to your transmission. Upgrading to a more efficient cooler can provide better cooling performance and protect your investment.

Types of Transmission Coolers

There are two main types of transmission coolers – air-cooled and liquid-cooled. Air-cooled coolers use airflow outside the vehicle to dissipate heat, while liquid-cooled coolers use coolant from the engine to regulate temperature. Air-cooled coolers are more affordable and easier to install, but they may not provide as much cooling efficiency as liquid-cooled ones. On the other hand, liquid-cooled coolers require more installation work but offer superior cooling performance.

Factors to Consider

When choosing a GM 10L90 transmission cooler upgrade, there are several factors you should consider:

1) Size – The size of the cooler will determine its cooling capacity. A larger surface area means better heat dissipation.
2) Material – Transmission coolers are made from various materials such as aluminum or copper. Aluminum is lightweight and corrosion-resistant while copper is more durable.
3) Fitment – Make sure that the cooler you choose is compatible with your vehicle’s make, model, and year.
4) Cooling Capacity – The amount of heat dissipated by a cooler is measured in BTUs (British Thermal Units) per hour.
5) Warranty – Look for coolers that come with warranties for added peace of mind.

Top Picks

After researching various options for GM 10L90 transmission cooler upgrades, I have narrowed down my top picks:

1) Mishimoto MMTC-DMAX-11SL – This air-to-liquid cooler has an impressive BTU rating of 17,500 and comes with an aluminum construction for durability.
2) Derale 13504 Series 8000 Plate & Fin Transmission Cooler Kit – This liquid-to-air cooler has an efficient plate & fin design with a BTU rating of 14,400.
3) B&M SuperCooler Automatic Transmission Cooler – This well-known brand offers both air-to-air and liquid-to-air coolers with various sizes and BTU ratings.

Installation

Installing a new GM 10L90 transmission cooler may require some mechanical skills or professional installation if you’re not comfortable working on your vehicle’s components. Make sure to follow the instructions provided by the manufacturer carefully.

Conclusion

Investing in a quality GM 10L90 transmission cooler upgrade is essential for maintaining your vehicle’s performance and prolonging its lifespan. Consider all factors such as type, size, material, fitment, cooling capacity, and warranty when choosing the right one for your vehicle. With proper installation and maintenance, you can ensure that your new transmission cooler provides optimal cooling performance for years to come.
