Maintaining the transmission is important. The fluid for it is bright red in color, clear and smells somewhat sweet if everything is working correctly. If this is what you find on your driveway, then all that needs to be fixed is the hole. If the fluid is dark or has a burnt smell then it’s time to get the fluid changed.
Check the fluid
To see if there is low fluid, take your car for a short drive to warm it up and then lift the hood and read the dipstick. Unlike motor oil, transmission fluid is not burned off or consumed by a car so if the level is low then there is a leak somewhere that must be patched. It is recommended to top up the fluid anyway even if the leak still exists to make sure there is enough fluid for the transmission to function properly until you get it fixed.
A car is supposed to run smoothly and without any shaking, or jerking, and without 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 get 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.
Any burning smell coming from your car 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. This 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.
