Beyond Oil Changes: Transmission Fluids Explained by Smith Brothers Transmission

The more frequently discussed engine oil often overshadows transmission fluids. While most car owners religiously schedule their oil changes, few consider their transmission fluid. However, neglecting your transmission fluid can lead to costly repairs and poor vehicle performance. At Smith Brothers Transmission, we aim to educate our customers about the vital role transmission fluid plays in keeping their vehicles running smoothly.

In this comprehensive guide, we’ll dive into the different types of transmission fluids, why they’re important, when and how often they should be changed, and how you can prolong the life of your vehicle’s transmission.

What is Transmission Fluid?

Transmission fluid is a specialized lubricant designed to help the gears in your transmission operate efficiently. It reduces friction, helps dissipate heat, and keeps all moving parts inside the transmission clean and lubricated. Vehicles have two types of transmissions: automatic and manual, each requiring a different kind of transmission fluid.

Automatic Transmission Fluid (ATF)

Automatic Transmission Fluid (ATF) is designed to meet the specific needs of automatic transmission systems. ATF serves multiple roles: it lubricates the moving parts, provides hydraulic pressure, and helps manage heat in the system. Modern ATFs are packed with additives like detergents, anti-foaming agents, and friction modifiers to improve performance and longevity.

Manual Transmission Fluid

Manual transmission systems use a different type of lubricant, often referred to as gear oil. Gear oil is generally thicker than ATF and serves primarily to lubricate the moving parts and protect the gears from wear. While not as multi-functional as ATF, gear oil is just as crucial for maintaining the health of a manual transmission system.

The Importance of Transmission Fluid

Transmission fluid is to your transmission what oil is to your engine: vital. Without proper lubrication, the transmission’s internal parts will wear out quickly, leading to expensive repairs or complete failure. Transmission fluid helps to:

• Prevent Overheating: The fluid absorbs heat generated by the friction between the gears and other moving parts, keeping the system cool.

• Ensure Smooth Shifting: In automatic transmissions, the fluid enables smooth shifting by maintaining the proper hydraulic pressure. Without the right fluid levels, your vehicle could experience delayed or jerky shifts.

• Extend Transmission Life: Keeping your transmission fluid at the right levels and ensuring it is clean can significantly prolong the life of your transmission.

At Smith Brothers Transmission, we stress the importance of regular transmission fluid checks and changes to prevent common transmission issues like slipping, overheating, and gear grinding. Our skilled technicians can perform these services efficiently and correctly.

When Should You Change Your Transmission Fluid?

Unlike engine oil, transmission fluid doesn’t need to be changed as frequently. However, that doesn’t mean it should be ignored. How often you should change your transmission fluid depends on several factors, including the type of vehicle you drive, your driving habits, and the manufacturer’s recommendations.

Automatic Transmission Fluid

For automatic transmissions, many experts recommend changing the fluid every 30,000 to 60,000 miles. If you do a lot of heavy towing or drive in harsh conditions, you may need to change it more frequently.

Manual Transmission Fluid

For manual transmissions, the interval is typically longer—around 30,000 to 50,000 miles. However, just like with automatic transmissions, extreme driving conditions may warrant more frequent changes.

You can always refer to your vehicle’s owner’s manual for manufacturer recommendations. If you're unsure when to change your transmission fluid or how to check it, feel free to contact Smith Brothers Transmission at (785) 357-7770, and our experts will be happy to guide you.

How to Check Transmission Fluid

Unlike engine oil, checking transmission fluid isn't always straightforward, as it may require warming up the vehicle or accessing a hidden dipstick under the hood. Here’s a simple guide to check your automatic transmission fluid:

1. Warm up the engine: Let your car run for a few minutes, allowing the transmission fluid to circulate.

2. Locate the transmission fluid dipstick: In most vehicles, the transmission fluid dipstick is near the engine’s back.

3. Check fluid level: Remove the dipstick, wipe it clean, reinsert it, and then remove it again to check the fluid level.

4. Check fluid color: Transmission fluid should be red or pinkish. If it appears dark brown or has a burnt smell, it’s time to change it.

5. Top off if necessary: If the fluid level is low, add the manufacturer-recommended fluid. Be careful not to overfill.

If this process seems overwhelming, we recommend having your transmission fluid checked and serviced by professionals. Smith Brothers Transmission has the experience and expertise to ensure your fluid is at the correct level and in good condition.

The Different Types of Transmission Fluids

It’s important to know that not all transmission fluids are created equal. There are several different types of fluids, each formulated for specific transmissions and vehicles. Using the wrong fluid can lead to inefficient operation and even damage. Here’s a quick overview of the most common types:

• Dexron/Mercon: These are some of the most common ATF types and are often interchangeable, depending on the manufacturer’s specifications.

• Type F: This fluid is specifically designed for older Ford models and should not be used in modern vehicles.

• HFM Fluids: High-friction-modified fluids are designed for specific types of automatic transmissions that require enhanced friction control.

• CVT Fluid: Continuously Variable Transmissions (CVTs) use a special fluid that provides better lubrication for the unique belt-and-pulley system found in CVTs.

At Smith Brothers Transmission, we use only the highest-quality transmission fluids recommended by your vehicle’s manufacturer to ensure optimal performance.

Signs Your Transmission Fluid Needs Attention

Knowing when to have your transmission fluid checked can save you from costly repairs down the road. Here are a few signs that it might be time to schedule an appointment with Smith Brothers Transmission:

• Slipping gears: If your vehicle slips out of gear or shifts unexpectedly, your fluid may be low or dirty.

• Delayed shifts: A delay in gear engagement when shifting from park to drive or reverse could indicate low transmission fluid levels.

• Strange noises: Grinding or whining noises, particularly when shifting, could be a sign that your transmission fluid is contaminated or low.

• Burnt smell: As mentioned earlier, if your transmission fluid smells burnt, it’s a strong indicator that it needs to be replaced.

If you notice any of these warning signs, it’s crucial to schedule a service immediately to avoid further damage to your transmission.

Prolonging the Life of Your Transmission

Beyond changing your transmission fluid regularly, there are a few other ways to keep your transmission in top condition:

• Avoid aggressive driving: Quick accelerations, sudden stops, and constant heavy loads can put unnecessary strain on your transmission.

• Keep your vehicle’s cooling system in check: Your engine’s cooling system also helps cool your transmission. Make sure it's functioning properly.

• Have regular transmission inspections: At Smith Brothers Transmission, we offer comprehensive transmission inspections to ensure your vehicle runs smoothly.

Finally, transmission fluid is an often overlooked but crucial component of your vehicle’s overall performance. Whether you drive an automatic or a manual, keeping your transmission fluid in good condition can help you avoid costly repairs and extend the life of your vehicle. At Smith Brothers Transmission, we’re dedicated to helping our customers understand the importance of proper transmission maintenance.
