Automatic transmissions are no longer just a premium feature; they are rapidly becoming a standard in modern mobility. With their smooth shifting and enhanced driving experience, automatics are transforming the market, making automatic transmission servicing an essential part of workshop operations.

In this article, we’ll explore the different types of automatic transmissions, the latest technological advancements, and how these impact servicing and fluid requirements.

What’s Driving the Change?

Traditionally, in Europe, automatic transmissions were reserved for luxury cars or offered as an optional upgrade. Most drivers learned to drive in manuals and stuck with them. In contrast, automatic vehicles have long dominated markets such as the US and Australia, where around 97 per cent of cars feature automatic transmissions, making manual gearboxes a less popular choice. Recently, however, as the cost gap between manual and automatic transmissions narrowed, more drivers made the switch for the convenience of automatics. The rise of electric vehicles (EVs), which typically do not have manual gearboxes, has further accelerated this trend. Moreover, changing driving habits—particularly in congested urban environments—have made automatic transmissions increasingly appealing due to their ease of use in stop-and-go traffic.

With automatics now steadily dominating new car sales, the demand for Automatic Transmission Fluid (ATF) servicing is here to stay.

Market forecasts indicate:

• Dual Clutch Transmission (DCT) and Continuously Variable Transmission (CVT) show significant growth together with traditional automatic transmissions, they are steadily replacing manual systems.
• ATF service fill requirements are becoming routine due to increasing vehicle lifespans and specific maintenance intervals, especially under severe operating conditions.

To service a car park that has become more automatic, and to prolong the lifetime of vehicle components, delivering the right product for each application and the right solution for each vehicle is vital.

ATF vs. Other Driveline Fluids

Automatic Transmission Fluid (ATF) is distinctly different from transmission fluid made for manual transmissions. Most modern passenger cars and light trucks sold today use automatic transmissions. Because these systems operate under varying conditions, selecting the right fluid is crucial for longevity and efficiency.

Automatic Transmission Fluid (ATF) – Function and Protection

ATF plays a critical role in ensuring smooth operation and longevity in automatic transmissions. Essential performance attributes of ATF include:

• Heat resistance and thermal stability: Prevents sludge and deposit formation under high-temperature conditions.
• Low-temperature flow: Ensures efficient hydraulic and electronic operation in cold conditions.
• Viscosity stability: Maintains optimal fluid thickness across a wide temperature range.
• Frictional properties: Regulates clutch engagement to ensure seamless gear shifts.
• Extreme pressure/load-carrying protection: Guards against wear and extends gear durability.

Understanding Modern AT Technologies

There are three primary types of automatic transmission technology available today: Stepped Automatic Transmissions, Continuously Variable Transmissions, and Dual Clutch Transmissions.

The Importance of ATF Changes

To keep automatic transmissions in top condition, fluid changes must be performed at the right intervals. For example, DCT fluid should be changed every 60,000 km—though this varies based on usage and load.

Using the correct fluid at the right time is crucial—neglecting oil changes can lead to transmission failure, which can be costly.

The Benefits of Correct ATF Selection and Servicing:

• Extended transmission lifespan
• More efficient power transfer
• Better fuel economy
• A smoother driving experience
