Transmission Fluid 101: What It Does and Best Options

Introduction

Transmission fluid is a vital component in vehicles with automatic transmissions. It serves as a lubricant, coolant, and hydraulic fluid for the transmission system. Without it, the gears and other components in the transmission would quickly wear out due to friction and heat.

The function of transmission fluid is to keep all moving parts within the transmission system well-lubricated while also providing cooling properties to prevent overheating. The fluid also acts as a hydraulic medium that facilitates gear shifting by controlling the movement of pistons and valves inside the transmission.

There are different types of transmission available on the market, including conventional automatic transmission (ATF), continuously variable transmission (CVT) fluids, dual-clutch transmission (DCT) fluids, and manual gearbox oils. Each type is formulated to meet specific requirements of different types of transmissions.

Transmission fluid flows through various openings in the torque converter, valve body, cooler lines, and pump before returning back to the pan where it is stored until needed again. The flow rate and pressure of the fluid are regulated by various components within the system such as pumps, valves, solenoids, and sensors.

It’s important to change your vehicle’s transmission regularly according to manufacturer recommendations or every 30k-60k miles or two-four years if not specified. Neglecting this routine maintenance can lead to damage within your vehicle’s engine resulting in costly repairs down-the-line. Additionally driving conditions like towing or heavy-duty driving may require more frequent changes than what’s recommended by manufacturers.

Types of Transmission Fluid for Cars, Trucks, and SUVs

Automatic Transmission Fluids

Automatic transmission fluid (ATF) is a type of transmission that is used in automatic transmissions. ATF is typically red or pink in color and has a slightly sweet smell. There are several different types of ATF available on the market today, each with its own set of properties and specifications.

One popular type of ATF is synthetic automatic transmission (synthetic ATF), which is made from synthetic base oils rather than petroleum-based oils. Synthetic ATF offers several advantages over traditional ATF, including better wear protection, improved fuel economy, and longer service life.

Manual Transmission Fluids

Manual transmission fluid (MTF) is a type of transmission that is used in manual transmissions. MTF is typically thicker than ATF and has a higher viscosity rating. MTF also contains additives that help to protect the gears and bearings inside the transmission.

There are several different types of MTF available on the market today, each with its own set of properties and specifications. Some common types include full synthetic MTF, which offers improved wear protection and longer service life than traditional MTF; diesel-rated MTF, which is designed for use in heavy-duty trucks; and Chrysler-specific MTF, which meets the unique requirements of Chrysler vehicles.

Continuously Variable Transmission Fluids

Continuously variable transmissions (CVTs) are becoming increasingly popular in vehicles today due to their smooth operation and improved fuel efficiency. CVTs do not have traditional gear ratios like automatic or manual transmissions; instead they use a system of belts and pulleys to change the gear ratio as needed.

Because CVTs rely so heavily on the properties of the transmission to function properly, it’s important to use the correct type of CVT fluid for your vehicle. Some common types include full synthetic CVT fluid, which offers improved wear protection and longer service life than traditional CVT fluids; Ford-specific CVT fluid, which meets the unique requirements of Ford vehicles; and UTI programs, which are designed to train technicians on the latest technologies and techniques for working with CVT systems.

Understanding ATF Labels and Misleading Information

Using the right Automatic Transmission Fluid (ATF) is crucial to ensure that a vehicle’s transmission system operates smoothly. However, many car owners and mechanics often overlook the importance of understanding ATF labels, which can lead to costly damages and voided warranties.

Misleading information on ATF labels can be confusing, especially for those who are not familiar with the technical jargon used in the automotive industry. Some manufacturers may use vague terms such as “lifetime” or “universal” to describe their ATF products, which can mislead consumers into thinking that these fluids do not require replacement or are suitable for all types of vehicles.

It is important to note that there is no such thing as a “lifetime” ATF. While some manufacturers claim that their fluids do not need to be changed, this is simply not true. Over time, all fluids break down and lose their effectiveness, which can cause significant damage to a vehicle’s transmission system if left unchanged.

To avoid falling victim to misleading information on ATF labels, it is essential to look for reputable brands and products that have been certified by industry organizations such as the National Institute for Automotive Service Excellence (ASE).
