Commercial Truck Transmission Repair: What You Need to Know

Commercial Truck Transmission Repair: What You Need to Know

Your commercial truck’s transmission could be going out, and you don’t even know it. Just one mechanical error in your transmission could cause your engine to shut down completely. It’s essential to follow the signs your commercial truck is telling you so that you do not further the damage to your vehicle and can have transmission repair before it becomes catastrophic. Transmission problems escalate in complexity the longer they are left unattended, so you’ll need to fix them as soon as possible. Find out what you need to know below or call our truck repair shop to schedule an inspection for your vehicle!

What Does the Transmission Do?

The transmission in your commercial truck ensures that the correct amount of power goes to your wheels at a given speed. This means that your transmission plays a vital role in controlling and handling your vehicle.

It works by shifting gears depending on the speed you are going. For instance:

  • The transmission uses a lower gear ratio (which provides more torque at lower RPMs) to provide enough power to get your commercial vehicle going.
  • Using a higher ratio ensures your truck can move at higher speeds while maintaining lower RPMs.

The transmission also helps increase fuel economy by maximizing the engine’s efficiency.

Signs of Transmission Problems

Several indicators could show you your commercial truck is having transmission problems. You should be aware of these and bring in your truck for an inspection if you notice any of the following:

  • Difficulty shifting gears
  • Grinding and other noises
  • Transmission fluid leak
  • Dragging or slipping clutch
  • Low power when accelerating

Transmission repair may be needed if you are experiencing any of the above symptoms. These issues do not go away on their own and could lead to long-term damage if left unattended.

Proper Transmission Maintenance

Your transmission in your commercial truck needs to be maintained correctly to avoid transmission repair. Scheduling routine preventative maintenance with our shop will ensure the longevity of your commercial truck’s transmission.

Transmission fluid flushes are a great way to ensure that no old fluid remains in your commercial truck. Typically, just draining the transmission will only remove about half of the old fluid, so it’s a good idea to have your transmission flushed and refilled with new transmission fluid.

Regular maintenance for your commercial truck’s transmission will:

  • Boost its life
  • Improve fuel efficiency
  • Ensure your truck has as smooth a ride as possible
