Transmission oil is one of the most important car fluids in your truck, preventing premature damage and keeping the engine operating smoothly. Whether you drive your own vehicle or operate a commercial truck, you need to know when to change the automatic transmission fluid to prevent malfunctions. Below are a few facts you should know about this liquid.

What Does Automatic Transmission Fluid Do?

To deliver power from the engine to the wheels, the transmission gears spin thousands of times per second. If they grind against each other, the resulting friction can damage the parts.

Automatic transmission fluid is formulated to lubricate these components, dispersing the generated heat and reducing wear and tear on the gears.

What Are the Signs Your Levels Are Low?

Your dashboard will usually indicate when the fluid levels are low.

A slipping transmission is one of the most obvious signs that your car fluids need to be changed or topped off. Your truck might also shift unexpectedly, or pause before changing gears.

Other signs include sudden increases in engine rotations per minute (RPM) before shifting, which could mean your transmission is having trouble engaging the gears. When you put the vehicle into drive or reverse, you might also notice a pause of several seconds before the transmission engages.

How Can You Check the Transmission Fluids?

Fortunately, checking your transmission oil is much like checking other car fluids. Start by pulling out the transmission fluid dipstick, then run the motor for several minutes until it’s warm. Insert the dipstick back into the transmission and pull it out.

If the oil isn’t pinkish and clear, you should have it changed by a maintenance professional. If it looks clean but doesn’t reach the “full” line on the dipstick, you can top off the liquid yourself.
