Common Transmission Problems

If you own a 2007 Nissan Sentra, you may have experienced some transmission problems. The transmission is a crucial component of your vehicle, responsible for shifting gears and transferring power from the engine to the wheels. However, over time, it is common for transmissions to develop issues. In this article, we will discuss some of the most common transmission problems that owners of the 2007 Nissan Sentra may encounter.

Slipping Gears

One of the most frustrating transmission problems is slipping gears. You may notice that your Sentra’s transmission slips out of gear while driving, making it difficult to accelerate or maintain speed. This can be dangerous, as it impairs your ability to control your vehicle. Slipping gears can be caused by worn clutch plates or a faulty transmission solenoid.
