In a nutshell, a car's transmission is in charge of transferring power from the engine to the wheels. As the car speeds up or slows down, the transmission permits the gear ratio between the engine and driving wheels to change. Depending on the type of transmission, different processes are used.
The transmission is responsible for severing the engine's connection to the drive wheel when a car comes to a stop. This makes it possible for the car to remain still when the wheels are not moving. A car's transmission enables speedy acceleration from idling. By lowering the engine's RPMs while maintaining or increasing the vehicle's speed, a transmission also aids in reducing the wear and tear on the engine.
Top 4 Transmission Failure Causes
The following are some of the main causes of transmission failure:
1. Insufficient transmission oil
Serious transmission problems including overheating (a genuine transmission killer), difficulty shifting gears, delayed gear engagement, and gear slippage can be brought on by low levels of transmission fluid. Drivetrain or seal problems might lead to a leak.
2. Filter clogged in the transmission
A clogged transmission filter may also cause transmission problems. As a result, the flow of (automatic) transmission fluid will be hampered (ATF). This will cause gear slippage, delayed transmission response, or grinding of the gears. This problem can be avoided by maintaining your transmission according to the factory-recommended timetable.
Issues with the torque converter
Damaged needle bearings are one issue that torque converters can experience occasionally. This may seriously harm the transmission. Strange noises coming from your transmission, such as a grinding or brushing sound, will be audible to you.
4. Solenoids problems
Controlling fluid flow throughout the transmission is the solenoid's job. Solenoid problems can be caused by low fluid levels and other electronic problems. Have the solenoid checked if a car's transmission is slipping but there are no obvious leaks.
Symptoms of Transmission Failure
These are some of the most prominent indications that a transmission is failing. The likelihood of an expensive repair considerably decreases if it is discovered early.
1. The check engine or transmission warning light
The presence of a transmission warning light or check engine light is a primary indicator of transmission failure. Although it's not a guarantee that the transmission is significantly damaged, if you see this, you should get your engine and transmission checked.
2. A burning odor
An automobile emitting a burning odor is never a good sign. This burning scent is frequently caused by a transmission that is overheating or by burning transmission fluid. To prevent further damage, the vehicle needs to be inspected right away if this is found.
3. Transmission fluid leaks
Leaking transmission fluid is one of the most visible symptoms of transmission failure. When a car is parked, this will appear as a sweet-smelling fluid underneath it. Make an appointment with a professional for an inspection if you notice transmission fluid leaking.
4. Slipping gears
This sign should not be taken lightly as it can be highly dangerous while driving. If a car slips in and out of gear while a vehicle is in motion, it should be assessed by a professional auto repair mechanic immediately.
Advice on Preventing Transmission Failure
Failure of the transmission can cause a lot of problems, both monetarily and otherwise. The life of your transmission may be extended easily and effectively with routine maintenance, which also helps avoid unanticipated, expensive repairs.
A key element in preventing gearbox failure is paying close attention to how a car sounds and drives. Early detection of the aforementioned symptoms increases the likelihood that the transmission won't fail.
Finally, a motorist should adopt careful driving techniques to avoid overtaxing the transmission. Your gearbox may wear down sooner if you have bad habits like moving an automatic transmission before the car has completely stopped, changing gears improperly, or parking without using the handbrake.
