A vehicle's transmission transfers power from the engine to the wheels, making it one of the most important components. Whether you have an automatic or manual model, understanding when you need transmission repairs helps you avoid large-scale problems that can cause the component to break completely, which is expensive to replace. Below are several indications that your transmission needs professional attention.

When Should You Schedule a Transmission Inspection?

1. Strange Smells

When driving, your engine should not put off any odors. While you may smell the exhaust when outside the vehicle, these fumes shouldn't get inside the cabin. If you do notice a strange smell while driving, head to an auto repair shop. If it smells like a chemical is burning, this signals that a part is overheating, such as the transmission. When this happens, the fluid inside will burn, preventing it from working properly. This can lead to total engine failure without prompt attention.

2. Leaking Fluid

The transmission uses a specialized fluid to ensure parts move smoothly and transfer power efficiently. If something damages the fluid reservoir or gasket, this liquid can leak from the vehicle, which could cause the transmission to seize and stop working. To spot this issue, look for a red liquid beneath the vehicle after you park (transmission fluid is generally red for most automatic transmissions, however it is a greenish/brown color in most European applications as well as most CVT transmissions). If you notice leaking fluid, avoid driving the vehicle until you can get transmission repairs. Trying to drive with this problem can cause the component to break completely, which requires you to replace it.

3. Problems Changing Gears

When a transmission starts to fail, the car will not shift to the next gear easily. If you have an automatic transmission, it might feel like the engine stalls briefly or has trouble accelerating. It may also shake as you increase your speed. With a manual transmission, you need to repair it if the gears grind, clunk, or hesitate when you try to shift. You might also notice the transmission "slipping" gears, which is when the proper gear doesn't engage fully. This is more common with a manual transmission, and it means that the car suddenly shifts into neutral.
