Understanding Transmission and Performance: Essential Insights for Drivers

Chris Salvino • March 22, 2025

Your vehicle’s transmission plays a vital role in its overall performance, but it’s one of the most misunderstood parts of your car. Whether you're driving through the bustling streets of Bethlehem, PA, or heading out on a road trip, ensuring your transmission is in top shape is crucial for both safety and performance. At Mary Street Garage, we’re here to explain how your transmission works, why it’s so important, and how regular maintenance can save you from costly repairs down the road.


What is a Transmission and Why Does It Matter?

The transmission is responsible for transferring power from your engine to your wheels, allowing your car to shift gears smoothly. In simple terms, it makes sure that your vehicle operates at the appropriate speed and power. Without a functioning transmission, your car wouldn't be able to move or function properly.


There are two main types of transmissions: manual and automatic. While the mechanics of each are different, both serve the same essential purpose—ensuring that your vehicle runs smoothly across a range of speeds. If your transmission is compromised, it can lead to issues ranging from poor fuel economy to complete vehicle failure. At Mary Street Garage in Bethlehem, PA, we specialize in diagnosing and repairing all types of transmission issues to keep your car performing at its best.


How a Healthy Transmission Affects Vehicle Performance

Your car’s transmission is essential for optimizing fuel efficiency, providing smooth acceleration, and ensuring that your engine runs at an ideal speed. When the transmission is in good condition, you’ll notice smoother shifts, better fuel economy, and an overall improved driving experience. However, when problems arise, your vehicle can experience sluggish acceleration, jerky gear shifts, or even complete failure to shift.


One of the most significant impacts of a malfunctioning transmission is reduced performance. If you’ve ever had your car struggle to shift gears or experienced strange noises when accelerating, you’ve probably encountered signs of transmission issues. It’s critical to address these concerns before they turn into a bigger problem, as unresolved transmission issues can lead to expensive repairs or even the need for a full transmission replacement.


Common Signs of Transmission Problems

At Mary Street Garage, we want to help you identify the warning signs of transmission issues early on to prevent major breakdowns. Here are some common signs that your vehicle may be experiencing transmission problems:


  • Delayed or Sluggish Shifting: If it takes longer than usual for your car to change gears, or if it shifts roughly, your transmission may be slipping.
  • Unusual Sounds: Grinding, whining, or clunking noises while driving can indicate issues with your transmission.
  • Warning Lights: If your "check engine" or "transmission" light comes on, it’s time to bring your car in for a diagnostic test.
  • Fluid Leaks: Transmission fluid is vital for the operation of your vehicle. If you notice red or brown spots under your car, you may have a leak.
  • Burning Smell: A burnt smell could indicate overheated transmission fluid, which can lead to serious issues if not addressed promptly.


If you’re experiencing any of these signs, don’t wait—bring your vehicle to Mary Street Garage for an expert evaluation. Our ASE-certified technicians can quickly identify the root cause of the problem and recommend the best course of action.

Why Regular Transmission Maintenance is Essential

Transmission problems often arise from neglecting basic maintenance tasks. Just like any other major component of your vehicle, your transmission needs regular care to function properly. Here’s why it’s crucial to stay on top of transmission maintenance:


  • Fluid Check and Replacement: Transmission fluid lubricates and cools the transmission. Over time, it can become dirty or low, which can lead to overheating and damage. Regularly changing your transmission fluid helps maintain smooth gear transitions and prevents damage.
  • Filter Replacement: The transmission filter helps remove debris from the fluid, ensuring that the fluid remains clean and effective. A clogged filter can restrict fluid flow and cause major transmission issues.
  • Diagnostic Checks: Periodic diagnostic tests can help detect potential problems before they cause significant damage. At Mary Street Garage, we use the latest diagnostic tools to thoroughly check your transmission for any signs of wear or malfunction.


By keeping up with routine transmission maintenance, you’ll extend the life of your vehicle, improve fuel efficiency, and ensure a smoother driving experience.
