If your transmission is producing a lot of heat and behaves as if it has little or no fluid despite having an adequate amount of fluid, the clutch inside of the torque convertor may be jammed. The torque convertor is what enables an automatic transmission to change gears. When a jam occurs, it causes the starter to lock and the transmission fluid cannot be properly calculated. This problem causes the transmission to behave as if it is low on fluid. Symptoms include shaking, excess heat and decreased engine power.
Excess varnish and gum can build up on the transmission and cause the valves to fail. Car owners can combat this by getting their transmission flushed once every three years. There are also come cleaners that can be used to remove gum and varnish from the transmission’s surface.
Low fluid is another common cause of transmission problems. When your transmission is running on low fluid, it can decrease the fluid pressure that it needs to perform basic operations. Weak fluid pressure can cause the transmission to fail or stop working completely.
A transmission can also malfunction or fail if there is a lack of cooling. Transmissions work best when they are at a temperature of about 175 degrees. Transmissions generate heat while they are in operation, so if there is a lack of cooling, it can overheat. You can decrease the risk of your transmission overheating by installing an external oil cooler. An external oil cooler works by using cool air from outside to cool the transmission fluid.
Sometimes the radiator in your car can leak, which causes radiator coolant to leak into the transmission fluid. When this occurs, the car fails to shift normally. It is important to always check your car’s radiator for leaks.
Using the wrong transmission fluid can cause severe damage to your car’s transmission. If you are not sure what kind of fluid your transmission requires, always have your car serviced by a professional. The wrong transmission fluid can cause you to need an entirely new transmission.
Transmission slipping is another common issue. When a transmission slips, it means that the power from the transmission is not being transmitted to the wheels. Slipping can occur if your transmission is dirty, has malfunctioning parts or a bad clutch.
The transmission filter is responsible for keeping debris out of the transmission fluid. A clogged or defective filter can cause your transmission to work improperly.
These are just a few of the causes of transmission problems. As always, take your car to a knowledgeable mechanic to find the real cause of your transmission problem and have it repaired as soon as possible.
