What are the signs of an automatic transmission failure?
2 Answers
There are several signs that indicate an automatic transmission may be failing: 1. Abnormal shift timing: Automatic transmissions typically have specific shift points based on engine speed and vehicle speed. If you notice that the shift timing suddenly becomes too long or too short, it suggests that the transmission's gear ratio is out of proportion. You may also feel that the engine is revving excessively, and in severe cases, the transmission may stop shifting altogether, indicating a problem. 2. Transmission fluid leaks: If you see fluid leaking from the transmission housing or oil pan, it could be due to aging seals causing poor sealing or manufacturing defects leading to porosity in the housing. 3. Transmission slipping, poor acceleration, or water ingress: While driving, if you hear the engine revving without a corresponding increase in speed, or the car feels sluggish, it's often caused by burnt clutch plates. Water entering the transmission due to external factors, such as coolant mixing with transmission fluid or water entering through the transmission vent, can also cause abnormal operation. 4. Unusual odors from the transmission: The transmission relies on hydraulic fluid to function. If the fluid temperature becomes too high, it can cause burning, emitting a noticeable odor, which indicates that certain components inside the transmission are not working properly.
Hey, I once experienced signs of a failing transmission while driving an automatic car, and it was truly awful. The car would suddenly jerk violently during gear shifts, as if something was stuck, turning the normally smooth upshifts into rough jolts—several times it nearly caused an accident. Then strange noises started appearing, like humming or odd clicking sounds, especially noticeable on the highway, and they were quite loud. Later, the transmission fluid level was low, and I smelled burning, which made me realize the problem was serious. Delayed shifting was also common—when accelerating, the car would take several seconds to respond, with unstable power output. Ignoring these warning signs can easily lead to slipping or a complete breakdown, and repairs can be costly. If you notice similar symptoms, I recommend going to a 4S shop immediately to check the fluid level and maintenance, so a small issue doesn’t turn into a big one.
