A diesel vehicle is often a significant investment, as their fuel contains between 10-15% more energy and can go around 20-35% further on a tank of diesel than a gasoline vehicle (per the EPA). However, they also have problems, such as issues with diesel transmissions that may make your car run roughly. Here are a few symptoms to watch out for when running your high-quality diesel vehicle.
Most diesel vehicles have a manual transmission, making them quite fun and sometimes even challenging to drive. They should shift quite smoothly once you get the hang of it, though. However, if you struggle to shift (particularly in trickier areas), you probably have a problem with your transmission. Slipping gears almost always indicates a significant problem with your transmission.
Your diesel vehicle will make plenty of noises as it drives. That’s nothing too unusual. However, you might notice some unpleasant transmission noises that can be a pretty big sign of issues as you ride. For example, humming, clunking, and whining noises usually indicate a myriad of problems. Usually, they show problems with the fluid pump that may cause diesel transmissions to fail on you.
When you shift your vehicle and drive for a long time, do you notice a rather unpleasant, burning smell? That may be your transmission fluid overheating and breaking down on you. This problem usually occurs if your fluid is old, and you don’t change it regularly enough. Replacing it may help here, though you may have already done too much damage to your transmission and need repairs.
Does your diesel shake or vibrate when you try to change gears? There could be a few things wrong here. The most likely problem is your transmission, as it may cause diesel to run poorly. However, you may also have issues with your suspension. The easiest way to tell is to gauge when the shaking begins. If it occurs when changing gears (and not while otherwise driving), it’s your transmission.
If you experience any of these symptoms with your diesel transmissions, it is essential to talk to a mechanic or repair shop right away to minimize any dangers. These professionals will work with you to help you understand what is happening. Then, if necessary, they’ll replace your transmission and provide you with a stronger and more secure vehicle. Doing so will help to ensure you get the best results possible.
