Automatic Transmission Fluids

Best Automatic Transmission Fluids with Avtoil

Choosing the right transmission fluid and maintaining it properly is crucial for keeping your vehicle's performance at its peak. Automatic transmission systems play a vital role in ensuring a comfortable and safe driving experience for every driver. Avtoil automatic transmission fluids are specially formulated to provide high performance and long-lasting durability.

The transmission is a complex electronic and mechanical system that transfers power through a gear system to move the vehicle. This system operates through the friction of the gears, which over time can wear down and lose functionality. By using automatic transmission fluid, you can minimize gear wear and ensure the system operates efficiently and smoothly

Key Features of Automatic Transmission Fluids

Automatic transmission fluids are distinguished by their ability to withstand low and high temperatures, prevent wear, and provide smooth gear shifts:

• Temperature range: Resistant from -40°C to +200°C

• Minimization of wear and sludge dissolution

• Protection of synchros and gear surfaces

• Maintains high-temperature performance and prevents oxidation

• Enhances driving comfort

DCT and CVT Transmission Fluids

• DCT (Dual Clutch Transmission): High-precision friction profile for dual-clutch gearboxes

• CVT (Continuously Variable Transmission): Special additives for infinitely variable ratios

Automatic transmission fluids are suitable for both passenger cars and light commercial vehicles. They differ from engine oils because engine oils are formulated to handle combustion byproducts and carbon deposits but are not optimized for gear and synchro friction.

How to Check Automatic Transmission Fluid

The dipstick method is the most effective way to check the condition of your transmission fluid:

1. Park the vehicle on a level surface.

2. Set the gear to “P” (Park) and apply the handbrake.

3. Open the hood and locate the transmission fluid dipstick.

4. Remove the dipstick, clean it, reinsert it, and then remove it again.

5. Check the fluid level according to the MIN and MAX marks.

6. Observe the fluid's color and smell: clean automatic transmission fluid is usually red or pink. Brown or dark fluid indicates it needs replacement.

7. If the fluid is below the MIN line, top it up.

8. When Should Automatic Transmission Fluid Be Changed?

   The replacement interval for automatic transmission fluid varies depending on the vehicle model, but it is generally recommended every 50,000–60,000 km. Following the manufacturer’s guidelines ensures long-lasting and trouble-free transmission performance.

9. Driving style, load, and climate conditions affect fluid lifespan

10. Heavy city traffic and high temperatures may shorten the replacement intervals

What Happens If Transmission Fluid Is Not Replaced?

Failing to change transmission fluid on time can lead to serious technical issues:

• Insufficient hydraulic pressure causes irregular gear shifts

• If fluid runs out completely, the vehicle may not shift gears

• Reduced fluid levels can lead to red fluid leaks

• Worn gears and components can cause severe damage to the engine and gearbox
