A vehicle is supposed to run smoothly and without any shaking, or jerking, and there is not supposed to be any grinding sounds. These all suggest that there is a problem with the gears. Manual transmissions commonly indicate problems by making a grinding noise or feeling when you shift into a gear. If the grinding occurs after engaging the clutch and shifting, this can be sign that the clutch may need to be replaced or adjusted. Automatic transmissions act a little differently. Instead of making a grinding noise, you will likely feel it take some time to wiggle into gear at first instead of the typical smooth transitions. As the problem gets worse, the transitions into the next gear become more jarring and involve more shaking. There are a few other reasons for grinding or shaking, but the appropriate course of action is still to have it inspected and serviced.
If the vehicle will not shift after engaging the clutch and trying to move the stick, take a look at the fluid to make sure that it is at the right level. Other causes include using the incorrect thickness of fluid and the clutch linkage or shift cables needing adjustment. The source of the problem could also be the vehicle’s computer system.
A burning smell coming from your vehicle is a cause for concern. Overheating transmission fluid is one of the causes of a burning smell. Transmission fluid helps keep the parts lubricated and cooled so that they don’t get worn out and damaged. If the fluid breaks down, the system runs too hot which it results in increased friction and corrosive activity as well as the build up of additional sludge and debris. If this is not taken care of, the transmission will eventually damage itself enough to break down completely. The end result is an expensive replacement. Common causes include low fluid level or using the incorrect brand or type of fluid.
The check engine light located on the dashboard is a great early indicator that something is about to go wrong with your vehicle, and in particular with your transmission. There are sensors placed in many areas of the engine that alert the computer if it senses unusual activity coming from a particular process. The sensors on a transmission can pick up on the slightest jerks and vibrations than you are not able to see or feel. When you notice an issue with the vehicle, make sure to bring it in as soon as possible.
