What are symptoms and signs of an automatic transmission problem? What are the problems with automatic transmission vehicles and how can they be addressed? What do the letters for automatic transmission vehicles mean?
Because of the increased number of vehicles in our country many people choose automatic transmission vehicles to avoid the hassle of driving. Contrary to popular belief the likelihood of an automatic transmission vehicle malfunctioning is very low. A gearbox that is not used with contempt and the oil change is not interrupted can easily travel 150 – 200 thousand km. Its biggest drawbacks include high fuel costs, high spare parts costs and labor costs when it breaks down.
The complex structure of automatic transmissions makes them difficult to understand. It is difficult to detect malfunctions in these complex devices using normal methods. However, it is possible to find problems while the vehicle is being driven, during repair. Special fault detection devices have been developed for all vehicle makes and models.
It is important to maintain your vehicle’s health and prevent any potential breakdowns. Service maintenance is essential in order to prevent any malfunctions from affecting other parts. Not only will it reduce accidents or leave you stranded but it will also help save you unnecessary money.
What parts are affected by automatic transmissions?
- torque converter
- Oil pump
- Gear clutch groups
- Transmission Housing
- sun gear groups
- Hydraulic valve body
- Electronic control parts
- Transmission seals
Common Causes of Failure
The most significant factor that can cause automatic transmission malfunctions is incorrectly applied oils. Incorrectly used oils can lead to oxidation disorders, damage to the transmission, and even permanent damage. This will prevent any malfunctions. It is important to use the oil specifications in the service booklets and should be checked periodically.
Problems with the transmissions can be caused by frequent sudden braking or sudden departures. The vehicle’s revolutions will automatically pass if there is no sudden braking. Triptonic gear vehicles are more susceptible to automatic transmission malfunctions. It can cause brain damage and reduce vehicle performance by shifting gears too quickly without revving.
Incorrect gear shifting is another reason for problems with automatic transmissions. It is essential that the latch be pressed before shifting. Without pressing the latch, transitions can cause damage to transmission parts and even breakage.
Transmission maintenance is important for people who don’t do it regularly. This can lead to automatic transmission oil leaking and automatic transmission knocking.
What are the Signs and Symptoms of Automatic Transmission Failure?
- When the gear is in the “D”, position, and the brake is released, the vehicle must drive forward on a downhill or flat road.
- The vehicle should remain in the “D” position when the gear lever is moved while the ramp is raised and the brake is removed. It should not reverse, but stand still and resist forward motion.
- If the vehicle is moving and the gear is in “D”, noise, vibration, and knocking should be avoided between gear shifts.
- The shift knob (ratchet), must be functioning properly. The torque converter is connected to the latch. If the latch jams, it means that there is a problem.
- The vehicle should sound stable while in motion.
- This is an indication that your transmission is not working properly.
Repair and maintenance
Expertise is required to repair transmissions, either manual or automated. First, identify the component that is causing the malfunction. Fault detection devices specifically designed for automatic transmissions can be used to identify the problem. Most common faults include problems with the transmission computer and torque converter. This can cause the car to lose traction and make it difficult to shift gears.
Original transmission parts are required for part replacement. Low quality spare parts can cause problems in the future.
What should users pay attention to?
You can use your automatic transmission vehicle for many decades without having to worry about it. Here are some tips.
- It is important to maintain the gearbox. Quality oil should be used for the vehicle.
- You should check the condition and oil of your transmissions regularly. The slightest disturbance in the gearbox can cause the entire gear system to cease working in harmony.
- As much as possible, avoid sudden braking and hard starting.
- Shifting gears requires that the shift lever be pressed. This latch controls the torque converter operation. If you don’t, the transmission gears could be damaged.
- It is not a good idea to use non-original transmission parts.
- When going downhill, the vehicle shouldn’t be in neutral.
- When the vehicle is moving, it must be kept in the “P” and “R” positions. If you do, it will cause serious damage.
- Hitting is not a good idea if the engine is not working.
- If the vehicle is in an accident or breaks down, it should be removed from the roads.
- If the vehicle is moving at a speed greater than 95 km/h, the gear selector should not be manually moved to the “2”, or “L” positions. Driving in the “L” position should not exceed 50 km/h.
- The vehicle should be in the “P” position if it stops for more than one second. If the transmission is not placed in the “P”, it will overload and reduce its lifespan.
The meanings of letters in Automatic Transmission Vehicles
P (Park). After you have stopped your vehicle completely, this is where you need to bring the gear lever. To avoid any damage, it is important to ensure that your vehicle stops completely.
R (Reverse) Similar to R in manual transmission. This is your vehicle’s reverse gear. You must first bring the vehicle to a complete halt before you reverse. Then, return it to its original position.
N (Neutral): In automatic transmission vehicles, it is used to neutralize the vehicle. This gear can be accessed when the vehicle is in a waiting position (e.g. red light, etc.).
D (Drive) This is the best position to use when moving your car. After pressing the power button or releasing the handbrake, you can move the vehicle by keeping your foot on its brake.
S or O (Speed, Overdirive): Sport or quick usage These buttons activate the normal gearshift and rev range of the vehicle. The acceleration and acceleration are increased. Maximize fuel consumption
L : Although it is not present in all vehicles, the general function of this mode is an automatic gear mode that provides different power when the vehicle is going up the ramp.
D1 and 1 The vehicle is forced to shift into 1st gear. You can use the engine compressor to reduce speed in downhill conditions or snowy weather.
D2 and 2: This forces the vehicle into 2nd gear. It can be used in exactly the same circumstances as above. When “2”, combined with “L”, mode on some vehicles, “L”, is used when ramping-up and “2”, when ramping-down.
D3 and 3: The vehicle is forced to keep in 3rd gear. This can be useful for those who require rapid acceleration and high speed.
D4 and D4 : It is not available in all vehicles. This means all gears.
– and +: These markings can be found on new cars, with automatic transmission, or triptronic transmissions that come with automatic transmission. Thanks to these – and + signs, you have the chance to adjust your gear status, such as manual gear. You can activate the mode by moving the lever in the forward and reverse directions.
