When it’s not working properly, you may notice a change in how the vehicle changes gears. This change can often be described as the transmission slipping. It collects and processes signals from the transmission to ensure gears are shifting consistently and effectively. The TCM controls how the transmission gears shift. ![]() The problem normally pops up when you have an issue with the transmission control module (TCM). You may not be able to find out that your car has a low transmission fluid pressure problem until you run it through a scan tool. You’ll want to have that checked and fixed by a professional. The torque converter uses fluid to send power to the transmission and to prevent the engine from stopping. This is normally a sign that the torque convertor needs a replacement. What you want to look out for are shifts that feel like they are completely out of place.Īt highway speeds of about 60 mph, you may also feel vibrations or hear a heavy-duty droning sound. Slight bumps that are almost unnoticeable are normal. You also want to pay attention to how the vehicle downshifts. You’ll feel the vehicle shift a little weird at slow acceleration, medium acceleration, or fast acceleration. If you feel the transmission slipping or jerking, you should try to diagnose the cause as soon as possible, before the potential repairs become much more expensive.Īs the vehicle moves from one gear to another, listen keenly as you also feel for bumps and jerking. Vibrations and a Jerking TransmissionĪ jerking transmission is one of the most common automatic transmission problems you’ll encounter while driving your car. Simply draining out the fluid and filling it up will not fix the problem. You’ll need to pull out the transmission to see what could be wrong. A burnt smell in the fluid is also a sign that your transmission is overheating or damaged. If it’s low, it will cause a deficiency in the hydraulic pressure needed to shift the gears. You can tell a lot by taking a look at your transmission fluid. To check the fluid, make sure the engine is running at its operating temperature. It can also run low especially if there’s a leak. Like other automotive fluids, it ages and loses its frictional properties. The transmission fluid helps to lubricate moving parts, facilitate gear shifts, and cools the transmission. Below are three of the most common signs that’ll tell you there’s a problem with your automatic transmission. An inspection will help determine whether you’ll need a simple fix or a major repair. When the transmission shifts hard or jerks from one gear to another, it could be a warning that you need to have it checked. Signs You May Have a Problem with Your Transmission
