The Importance of Transmission Services for Cars and Trucks

Wilson Motorsports • February 6, 2025

The transmission: one of the most important parts of your vehicle.

At Wilson Motorsports Auto Repair in beautiful San Jose, California, we understand that the transmission is one of the most important parts of your vehicle. It’s responsible for transferring power from the engine to the wheels, allowing your car or truck to move smoothly. Without a properly functioning transmission, you could run into serious trouble on the road. That's why transmission services are essential for the long-term health of your vehicle.


What is a Transmission?

Before diving into why transmission services matter, it’s helpful to understand what the transmission actually does. In simple terms, it controls the power from the engine and adjusts it to change gears, helping your vehicle accelerate, decelerate, and move in reverse. There are two main types of transmissions: automatic and manual. Automatic transmissions do this work for you, while manual transmissions require the driver to shift gears manually.


Why is Transmission Service So Important?

Your transmission works hard every time you drive. Over time, the fluid inside it can become dirty or low, which can lead to problems like slipping gears, delayed shifting, or strange noises. Regular transmission services, like fluid checks and changes, can prevent these issues and ensure your car or truck runs smoothly. Here’s why transmission services are so important:

  1. Prevent Costly Repairs: Transmission repairs or replacements can be expensive. By keeping up with regular maintenance, like fluid checks and flushes, you can avoid major transmission problems down the road.
  2. Extend the Life of Your Vehicle: Regular transmission service helps your vehicle last longer. When the transmission is well-maintained, it runs more efficiently, which can also improve your fuel economy.
  3. Avoid Dangerous Situations: If your transmission fails, it can cause your car to stop running or struggle to shift gears. This can leave you stranded on the road or, worse, cause an accident. Regular services help prevent these dangerous situations.
  4. Smooth Driving Experience: No one wants to drive a car that jerks, hesitates, or makes strange noises. A well-maintained transmission ensures smooth acceleration, deceleration, and shifting for a more comfortable and enjoyable ride.


What Does a Transmission Service Include?

Transmission services can vary, but most commonly, they include:

  • Fluid Check and Replacement: Transmission fluid lubricates the components inside your transmission, preventing friction and heat buildup. Over time, this fluid can become contaminated and lose its effectiveness. A transmission service includes checking the fluid level, condition, and replacing it if necessary.
  • Filter Replacement: The transmission filter helps keep dirt and debris out of the transmission. If it becomes clogged, it can cause your transmission to malfunction. Replacing the filter is part of regular transmission maintenance.
  • Fluid Flush: A transmission flush involves removing all the old fluid and replacing it with fresh fluid. This is a more thorough service than just topping up the fluid, and it helps keep the transmission in top condition.
  • Diagnostic Check: A technician may also run diagnostics to check for any potential problems, such as slipping gears or strange noises, which could indicate that a more serious issue is brewing.



How Often Should You Get Transmission Service?

The timing for transmission service varies depending on the make and model of your vehicle. However, most experts recommend having your transmission fluid checked every 30,000 to 60,000 miles. If you do a lot of towing or use in heavy duty applications we would recommend transmission services about twice as often or every 15,000 to 30,000 miles. Always check your vehicle’s owner manual for specific recommendations, and don’t hesitate to bring your car or truck in to Wilson Motorsports Auto Repair in San Jose, California for an inspection if you notice any signs of transmission trouble.


Signs You Need Transmission Service

Keep an eye out for warning signs that your transmission may need service, such as:

  • Slipping gears
  • Rough or delayed shifting
  • Grinding or whining noises
  • Warning lights on the dashboard
  • Leaking transmission fluid (red or pink fluid)

If you notice any of these symptoms, it’s crucial to get your transmission checked by a professional to avoid further damage.
