Common Errors Made by Drivers in Automatic Transmission Cars
Common Errors made by drivers in Automatic Transmission Cars
Automatic transmission is no doubt a boon for the car industry, creating unimaginable convenience for drivers – professional or amateur. Especially advantageous for Indian driving and traffic conditions, AT cars are becoming more and more popular and affordable. However, those who are recent converts to AT vehicles commit some common mistakes and then have a hefty repair bill on their hands. Here is our list of the 5 biggest mistakes people make in automatic gearbox cars:
1.Driving down a slope in Neutral Mode – Generally neutral is opted to save fuel but switching to ‘N’ while driving down a slope is precarious for the gearbox. It might result in cutting down the oil supply and preventing the transmission from acquiring decent lubrication, which might damage the gearbox. This might also hamper the driver’s ability to control the vehicle.
2.Sticking to Neutral at Traffic lights – This is done frequently by drivers to save fuel and shield the gearbox from damage. Shifting frequently between N and D is bad for the gearbox, hence it is wiser to apply brakes and maintain the transmission in Drive mode if the waiting time is less than 2 minutes.
3. Launch control – Unlike manual transmission cars which enable the driver to have control over starting the car, automatic transmission cars are furnished with a launch control component. Usually, people newer to auto gears ignite the engine before changing the gear to ‘D’ mode causing shaky launch and damage to the engine as well as the gearbox. So, the driver should initiate an automatic transmission car by keeping the mode in Drive, lowering the brake pedal, accumulating speed and then moving up from the pedal when ready to launch.
4. Changing gears without stopping from D to R, R to D and P – Auto transmission technique utilises transmission band and clutches to shift gears. That’s why changing the direction mode from ‘D’ to ‘R’ or ‘R’ to ‘D’ needs to be considered after reaching to a halt or else one should be ready to face the consequence.
5. In parking mode of auto transmission – The car comes to a halt and is debarred from moving backward or forward if the gear is changed to ‘P’. So, one should be careful not to shift the gear while the car is in motion to avoid any unwanted outcome. It is always better to change the gear to ‘P’ mode when the car is static.
TOP 8 REASONS WHY YOUR TRANSMISSION MAY BE FAILING
You know your vehicle. So when it starts acting differently, you take notice. Are you currently hearing strange sounds or is there a peculiar smell coming from your vehicle? Is it handling differently than normal on the road? The most important thing is properly diagnosing the root cause of your vehicle’s issue. Below are the tops reasons or signs that you may require transmission repair:
COMMON REASONS FOR TRANSMISSION PROBLEMS
The top signs why your transmission may be failing:
You may be experiencing a problem with your transmission if your vehicle is exhibiting any of the following symptoms below:
1.Transmission won’t engage or stay in gear
If when you put your vehicle into gear and it won’t move, this may be a problem with low transmission fluid due to a leak, the shifter, shifter cable, or it could even be a problem in the valve body of your automatic transmission. Newer vehicles depend on the computer to tell the transmission when to go into gear based on your selection and you may need to have the computer system checked for trouble codes.
2.Shifts are delayed or missing gears
If your transmission takes a while to go into gear, you may have a low transmission fluid condition because of a leak or contamination due to lack of maintenance or even water intrusion during off road or flooding conditions. While this may not sound serious, but this can also create an overheating condition that can damage internal transmission parts. Other possibilities could be an engine related problem that will cause the computer to not allow the transmission to shift into higher gears.
3.Transmission slipping or engine is revving high
This condition can also be caused by low transmission fluid, contamination due to lack of maintenance or water intrusion, or internal wear and tear on the transmission parts inside the transmission. A high revving engine is a typical sign that you have worn clutches or other parts inside the transmission going bad.
4.Transmission fluid is leaking
A red fluid under the vehicle is a sign that you probably have a transmission fluid leak from one of the cooler lines, a gasket or a seal. This is not only bad for the transmission but is also dangerous if the fluid leaks on a hot pipe or other surface. Check your dipstick for proper fluid level and condition. Note: not all transmission fluid is red and not all levels can be verified with a dipstick method, but require specials tools.
5.If there’s a burning smell
A burning smell is typically caused by a fluid leak or in some cases by low fluid causing a burning clutch smell. If you catch the fluid leak quickly you might be able to save the transmission from damage. Check your transmission dipstick as per the manufacturer’s direction for level and condition.
6.If there is buzzing, clunking, humming noise
A buzzing, clicking, humming, roaring noise from inside the transmission is usually a symptom of a bad bearing, planetary gears damage, or other internal problem. A buzzing could also come from a bad internal sealing surface, a seal, or low transmission fluid due to a leak.
7.Car has no power
If the vehicle has no or little power and the engine is running correctly, this could be from internal transmission problems, brakes that are dragging due to a faulty caliper or brake hose, or your computer in the vehicle is limiting power because of a problem it has detected in order to protect the engine. Have the vehicle checked for trouble codes to isolate the problem.
8.Check Engine Light or Over Drive Light is on
A check engine light is not dedicated to the engine only. A check engine light can also tell you that you have problems with the transmission including overheating, solenoid problems, speed sensors, slipping transmission, and many other problems. Have the trouble codes retrieved to see what systems and circuits are indicating a problem. While not all sensor related codes mean the sensor is bad or will repair the issue, it will give you a starting point for the concern.
