Are Transmission Services Really Necessary?

Transmission Services; Why Are They Important?

When thinking of vehicle maintenance, many people know their oil needs to be changed regularly and that their tires need to be rotated. One of the systems that is often overlooked is the transmission system, the key component that transfers power from the engine and makes it usable at the wheels. So why is it important to service the transmission and keep it maintained?

We know it’s important to change our engine oil often, as there are tons of moving parts that need to be lubricated to create the power that keeps us getting to work, picking up the kids, and running to the grocery store. The transmission allows your car to move at different speeds while also managing the engine's power output.

With today’s technology and engineering, many different types of transmissions have come into play in our vehicles. Most of society has moved on from the standard manual transmission to the automatic transmission for reasons including performance, efficiency, and fuel economy. There are many different types of semi and fully automatic transmissions, such as the CVT (Continuously Variable Transmission) and DSG (Direct Shift Gearbox). They all work slightly differently for different applications, but serve the same purpose. Putting power to the ground and getting you moving. And if you guessed that they all need to be serviced, you’re right!

With so many different transmissions, you would think servicing them is a potential pain in the neck and you might prepare yourself for a headache. But there’s no need, there’s actually only a few things that are very important to making sure your transmission lasts the way it’s supposed to. Using the right fluid is one of those things. Different transmission systems require different fluids to properly lubricate all of those moving parts. Some even require vehicle-specific fluids that have different properties and contain additives. Using the wrong fluids can cause problems such as overheating, burning, slipping, and hard shifts. Once these problems start to occur, the damage is already done and there's a significantly higher risk for overall failure.

The most important aspect of servicing your transmission is doing it on time. We see the most problems with transmissions that are overdue or simply have not ever been serviced. The old fluid gets dirty, burns, breaks down, and can even turn into more of a sludge than a fluid. When this happens, it’s impossible to lubricate everything properly and keep the right tension and resistance needed within these technical, sensitive systems. (It also clogs the filter that some transmissions have, which is not helpful considering the filter's job is to keep everything clean and moving freely. Theoretically, the filter should be replaced with every service. But, there are times that the filter is in good shape and can just be cleaned and put back, saving the customer the cost of a new filter.) This causes all of the aforementioned problems like slipping, burning, overheating, hard shifts, and complete failure.

We recommend that these systems be serviced every 30,000 miles. Some manufacturers are now offering “lifetime fluid”, but we’re honestly not huge fans of that idea. When the internals are under pressure, moving at high speeds, going through cold and hot cycles, and hauling the weight of your entire car, we know that the fluid is going to break down to some extent and there is going to be wear and tear. Unless the transmission’s lifetime is expected to be rather short, we’re not sure how it’s supposed to hold up. We recommend staying on the safe side, and getting it serviced. It will help ensure smooth gear shifts, optimal fuel efficiency, and overall improved driving experience. Yes, fuel economy can be affected if the transmission has to work harder and requires more power from the engine. Neglecting transmission care can impact your vehicle's responsiveness and efficiency, and even pose a safety risk if it fails while you’re driving!

Although this blog is primarily about the importance of getting transmission services done, it wouldn’t be right to leave you unaware of the potential risks of these services in some vehicles. There is a risk for damage in older vehicles with high mileage that haven’t been serviced before or have not been serviced in a long time. Usually in these specific cases, the culprit is friction maternal from the clutches. It acts as a friction modifier within the system and the transmission gets used to the extra friction from the old fluid, wearing accordingly. Then when you add clean, new fluid, sometimes there is not enough friction to engage the internals. This will cause slipping between and in gears, hard shifts, and ultimately failure. Our recommendation for servicing transmissions in these situations is to not service them at all, or talk to a certified mechanic to see what the risks are depending on the age, mileage, and service history of the vehicle. However, this can all be avoided if the services are done as called for!

Regularly servicing your vehicle's transmission is not just a maintenance task—it's a crucial step in ensuring your vehicle's longevity, performance, and safety. It’s typically a pretty inexpensive service that can save you from a tow truck and a costly repair down the road if done the right way. No one wants to get stuck on the side of the road, so don't wait for warning signs! Make transmission services a regular part of your vehicle care routine. Your car will thank you, and you'll enjoy the peace of mind that comes with knowing you're taking good care of your investment. We hope this gives a better understanding of why transmission services are important to those who are looking, and as always, you can reach out to us at (973) 366-3777 or visit our website to learn more about transmission services.

Drive Belts & Pulleys: The Unsung Heroes Under Your Hood

April 9, 2025

When it comes to car maintenance, there is a lot that comes into play. It can almost be overwhelming at times. Focus on common wear items like the battery, brakes, and tires are usually at the top of the list for most, but there are other items that need attention as well. Drive belts and pulleys are some of these items. These small components help keep your car running smoothly, and after a while they do wear out and need replacement. Unfortunately, failure can lead to a breakdown on the side of the road and leave you needing a tow. So what are they and what do they do? Let’s find out. What Are Drive Belts and Pulleys? Think of drive belts as super strong rubber bands that transfer power from your car’s engine to help run other important components. The pulleys are similar to any other pulley; they are just metal wheels that help guide and control the belts movement. However, these pulleys are attached to other engine accessories, and when the belt spins the pulleys they provide power to these other accessories. Together, they keep essential parts of your car operating. Most modern cars use a serpentine belt, a long, continuous belt that is wrapped around multiple pulleys that power multiple systems. Older vehicles might have V-belts, which are shorter and typically run a single component at a time. What Do Drive Belts and Pulleys Power? Drive belts are made from durable rubber and reinforced materials, but they don’t last forever. Over time, they can crack, stretch, fray, glaze, or even snap. Pulleys have a lifespan as well. They are subject to corrosion and the bearings can go bad and even seize up completely. Without drive belts and pulleys, several key systems in your car wouldn’t function properly. Here’s what they keep running and what can happen if they fail. Alternator – Powers your car’s electrical system and keeps the battery charged. If the belt breaks, your battery will eventually die, leaving you with a car that won’t start or may die while you are driving. Water Pump – Circulates coolant to prevent your engine from overheating. A broken belt could lead to severe engine damage due to overheating. Power Steering Pump – Makes turning the steering wheel easier. If the belt slips or breaks, steering your car instantly becomes much harder, especially at low speeds. Air Conditioning Compressor – Helps keep your car cool on hot days. While not as critical as other components, losing A/C can be uncomfortable. Drive Belts and Pulley Maintenance Drive belts and pulleys don’t necessarily require maintenance, but they should be inspected regularly. In some cases, a bad pulley can cause the belt to slip or even pop off of the pulley completely. There are a few things to look for that may tell you it’s time for replacement. Check for Cracks, Fraying, or Glazing – Look for visible signs of wear on the belt. If you see cracks, missing ribs, fraying, or a shiny, glazed appearance, it’s time for a replacement. Listen for Strange Noises – A worn out belt or pulley may slip on the pulleys and cause a high-pitched squealing, chirping, or rattling noise when you start the car or turn the wheel. Watch for Performance Issues – If your battery warning light comes on, your power steering feels heavy, or your car starts overheating, a belt or pulley could be the culprit. Have Regular Inspections – Most belts last between 50,000 to 100,000 miles, but checking them during routine maintenance can prevent unexpected failures. Replace Before It Fails – A worn belt may still work, but it could snap at any moment. Replacing it early saves you from the headache of a sudden breakdown. Final Thoughts Drive belts and pulleys may not be the most glamorous parts of your car, but they play an essential role in keeping your car running smoothly. Keeping them in good condition helps ensure your car stays reliable and safe. At Automotive Magic , we offer a bumper to bumper vehicle health inspection that includes checking belts and pulleys for wear. Our inspections are sent to you with photos, videos, and descriptions explaining any issues we find with your vehicle and their severity to keep you on the road with confidence.
