How Do You Know if You Have a Bad Transmission?

A transmission plays an important role in the operation of your car. And if the transmission goes, it can be an expensive problem to fix. Luckily, many cars give off warning signs that it needs repair before it completely dies. Unfortunately, many people have no idea what these warning signs are. If you don't know what the warning signs are, don't feel alone. I was once in the same position and ultimately, it caused me to have to replace the transmission in my car because I missed these signs. I created this website to help others identify when it needs to be repaired. If you notice any signs of a problematic transmission, head to a repair shop quickly to save yourself a lot of money!

Six Tips For Making Used Freightliner Trucks More Efficient

Diane Bishop

If you are buying a used freightliner, you'll save a lot compared to buying a new one, but you may sacrifice a bit of fuel efficiency in some cases. Luckily, the difference is generally marginal, and there's a lot you can do to boost the fuel efficiency of your new-to-you truck. Take a look at these tips and ideas.

1. Trailer Tails

Trailer tails can be retrofitted onto the backs of most trailers. They look almost like sails or fins coming off the rear doors of the trailer. These tails are adjusted in a way that helps the air to stream over the trailer in an aerodynamic fashion. They eliminate the turbulent airflow that is otherwise found at the back of most trailers.

As an added bonus, they also add a crumble zone at the back of your trailer. If there is a multi-car pile up and the car behind you runs into your trailer, these tails can help protect the trailer from damage.

2. High-Flow Exhaust System

To really boost the fuel efficiency of your used freightliner, you may want to put in a new high-flow exhaust system and high-flow air filter. These components can also be bought and installed aftermarket. They allow more air to get to the engine. That helps the motor breathe and leads to greater efficiency.  

3. Tire Pressure Monitoring System

Many used freightliners have a tire pressure monitoring system built right in, and you may want to look for that feature. However, if you've found the perfect freightliner but it doesn't offer that feature, you may want to consider adding an aftermarket monitor.

A tire pressure sensor keeps an electronic eye on the tires. If the pressure is too low, the sensor alerts you. That way you know that you need to add air. Tires with low pressure take more energy to roll along the road than tires that are adequately pumped up. As a result, they have a negative effect on your fuel economy. In addition to putting in a tire pressure monitoring system, you may want to upgrade to the best tires possible.

4. Aerodynamic Wheel Covers

Even the wind running past your wheels can have an impact on fuel economy. If the wheels have lots of ruts and grooves that the wind can go into, it won't run as easily over the tires. That, in turn, creates a small amount of drag. Luckily, there are aerodynamic wheel covers that can help. In most cases, you just connect them directly to your existing wheels.

5. Side Skirts

While you are down there putting on the wheel covers, you may want to think about side skirts. Also called trailer skirts or side panels, these panels affix to the long edges of your trailers, between the wheels. By making the trailer more aerodynamic, they also reduce how much gas you need to use on each journey.

6. Trailer Top Fairing

You may also want to look into fairings for the top of the trailer. These fairings can be put on the top edge of a trailer, and when used with other types of fuel efficiency tools such as side skirts, they can boost efficiency by up to 12%. They are also effective if you haul two trailers at the same time. They help the wind to move over the gap between the two trailers without creating a lot of drag.  

To learn more, contact a used semi salesperson. They can show you the most efficient models in their inventory, and answer all of your other questions as well. Then, before you know it, you can be on the road in the used freightliner.
