Your car's transmission is a complicated system with numerous parts. It is a transmission's job to transfer engine power to the wheels. It controls an automobile greatly and accomplishes this by changing gears.
There are a few potential causes of the issue if the automatic transmission in your car isn't shifting gears. Most likely, you'll need to visit a mechanic so they can correctly identify the problem and fix it. There are numerous causes for transmission to fail to engage a gear. See a few key explanations on CarsBite.com below.
In an automatic transmission, the torque converter performs the same function as the clutch mechanism. Among the parts of the torque converter are a turbine, a stator, and a pump. Any of these components may develop a flaw, which would result in slippage as your transmission changes gears. Additionally, it can prevent the transmission from shifting at all. The torque converter may be repairable, but if the damage is severe, your mechanic may suggest replacing the torque converter with a new one.
Transmission fluid is necessary for automatic transmissions to function properly. ATF is the name of the automatic transmission fluid. The fluid characteristics of the transmission fluid can be impacted over time by the accumulation of dirt, debris, and other minute particles. When you try to shift gears because of this, the car can stop working.
The lifespan of the transmission will be increased by replacing contaminated transmission fluid in accordance with the suggested maintenance schedule for your car. We advise using the same transmission fluid the automaker suggests.
An automated transmission is composed of three systems: mechanical, hydraulic, and electrical. For the transmission to function successfully, these systems must cooperate. The electrical system keeps an eye on the throttle position, gear selection, and speed. The Electronic Control Module (ECM), a car's internal computer that aids in automatic gearshifting, is a part of this system. You could face transmission issues if the ECU sustains some form of damage or bug. You might wish to get the ECU reset or changed by a skilled OEM technician if the transmission is acting strangely.
Automatic gearbox vehicles typically have a shift lock mechanism that prevents you from unintentionally shifting out of Park while your car is parked. If you don't apply the brakes first, you can't shift into Neutral or Reverse. Because of this crucial safety feature, the car won't roll if a curious child or careless passenger accidentally bumps the gearshift. However, if this solenoid is faulty, it might not detect when you apply the brakes.
An automatic transmission's shift lock override is standard. To learn more about how yours functions, consult the owner's manual. It usually has a slot in the console. Some vehicles, such as Toyotas, have a button to manually unlock the shifter.
