In automatic transmission cars, there is no need to shift the gears manually. During car operation, the transmission automatically increases and decreases vehicle speeds as it delivers the power of the engine to the wheels. The performance of an automatic transmission system influences the overall performance of the entire vehicle greatly. Hence, even the slightest transmission issues can lead to major repairs being required if left unattended for a long time.
If you have an automatic car, watching out for signs of a compromise in your transmission operations can help to keep vehicle repair costs at a minimum. The following signs indicate there may be faults in your transmission's operation.
You Transmission Is Noisier Than Usual
Quiet transmission operation is an indication of a normally functioning transmission. If you hear unusual noises coming from your auto transmission system when the vehicle is moving, don't ignore the noises – they're a sign that your transmission is in trouble!
There are a variety of transmission noises that you may notice, but some tend to be more common than others. Some of the typical noises that your transmission can make include humming, grinding, clunking, and whining.
Grinding noises coming from your transmission may be an indication of moving parts rubbing against each other due to poor lubrication, for example. If the problem is ignored, it may accelerate wear, thus leading to premature parts-replacement.
Your Transmission Is Running Too Hot
Does your transmission have a burning smell? If so, this is an indication that your automatic transmission is overheating, and the transmission fluid is the most likely culprit.
Automatic transmission fluid is the motor fluid used to lubricate your transmission system and help keep it cool. Over time, the fluid degrades and loses its lubricating and cooling abilities. When this happens, it will no longer be effective at its job of preventing internal friction between all the moving parts. This, in turn, causes transmission overheating.
If you notice a burning smell or excessive heat coming from under your car, you should take action before it's too late. Check your transmission fluid level. If it's lower than normal, you might have leaks that need to be sealed before the fluid level can be replenished. If your fluid level seems normal, the fluid might be contaminated and only needs to be changed.
As it is an integral system in your vehicle, the automatic transmission should be kept healthy at all times. Be sure to seek out an auto transmission repair technician whenever you suspect that your transmission operations are compromised.
