How to select the best automatic transmission fluid for your fleet

Today’s automatic transmissions are designed to deliver better power and performance to your fleet than the manual transmissions of the past, but they can’t reach their full potential without protection from a premium lubricant.

When it comes to fleet management, automatic transmission fluids (ATFs) can be an afterthought. But without them, your operation will suffer. Knowing how to select the right ATF will protect your bottom line, giving you peace of mind year-round. 

Here are three factors to consider when selecting fleet transmission fluid

1.  Ensure the product is backed by a reputable dealer and meets the specs of the original equipment manufacturer

Using a licensed transmission fluid means your fluid meets the highest standard of quality — a standard set by transmission manufacturers. The Allison Transmission, for example, is a global leader in heavy-duty automatic transmissions, and its latest specs are referred to as Allison TES 668. Products with TES 668 licensing, like Cenex^® maxtron^® ATF SS8, meet the most demanding standard related to fluid stability, lubrication and cold operation, with proven benefits like:

• Longer drain intervals
• Enhanced transmission performance
• Lower operating costs
• Optimal transmission protection

2.  Consider a full-synthetic ATF

Full-synthetic ATFs, like Maxtron ATF SS8, are proven to outperform mineral-based fluids in several key areas, including:

• Protection in extreme temperatures, resulting in better cold starts
• Enhanced friction modifier durability, meaning fleets can run hotter for longer
• Improved anti-wear, which extends the life of your transmission

Regardless of temperature and load variations, full-synthetic ATFs ensure fleet operators have better overall performance and smoother shifts.

3.  Choose products that can help streamline your operation

Allison TES-licensed products like Maxtron ATF SS8 are backward-compatible. Fluids that are licensed with the latest Allison specs are made for newer transmission models but can bring the same advantages and benefits to older vehicles. This means you can simplify your maintenance routine with a fluid that can be used across your fleet.   

Don't leave your transmission's full potential untapped. Using a high-quality ATF allows your vehicles to go a lot further for a lot longer. Before purchasing an ATF, read your owner's manual or check the equipment lookup tool.
