Causes of Automatic Car Transmission that Cannot Shift Gears
The inability of an automatic car's transmission to shift gears is a sign that there is damage to the transmission system and can cause the gear lever to get stuck. The most noticeable impact is that the automatic transmission lever becomes difficult to shift from parking or neutral mode to other positions.
Perhaps by trying a few times, the problem can be resolved and the automatic car can run as usual. However, this condition should not be taken lightly. You need to realize it immediately to avoid more extensive damage.
So what makes the automatic car's gear lever difficult to shift? Here is a more detailed explanation.
Problems with the brake switch
The inability of the automatic car to shift gears is caused by issues with the brake switch. When the brake pedal is pressed, the brake switch does not get activated.
This condition prevents the transmission lever from shifting even if the brake pedal is fully pressed. The easiest sign to identify this condition is the brake light not illuminating when the pedal is pressed.
In fact, damage to the brake switch is a form of prevention to avoid accidents while driving. Once you know the source of the problem, you need to analyze and replace the faulty part.
Does the brake switch need to be replaced or just readjusted? Here are the steps to check the problematic brake switch.
1. Open the fuse box located in the engine compartment. Then look behind the fuse box cover for the code indicating the tail lamp fuse. Check the fuse to see if it is blown or not. Do this by removing the fuse and checking if the conductor is still connected or broken. If it is broken, replace it with a suitable size.
2. This condition may be caused by a loose socket. You just need to tighten the socket until it clicks, and the brake switch function returns to normal.
3. If the two problems above are not found, it may be that the adjustment is not correct. Sometimes the brake switch does not function if the switch adjustment is too far away. Use a 12 mm wrench to readjust, turning it left or right until it functions normally again.
4. The last step is to replace the brake switch if the three methods above do not work.
Dirty brake switch
Still regarding the brake switch, the symptom of the automatic car's transmission not being able to shift gears can be caused by a dirty brake switch due to dust, dirt, or even accumulated lubricant residue. As a result, the brake switch cannot send signals, making it impossible to shift the transmission lever.
This condition usually occurs when the car engine is cold. When warmed up, the dirt can dissolve, making it easier to shift the transmission. So don't ignore this issue, even though it can be resolved without action. Sometimes the age of use and the condition of the dirty brake switch can hinder the driver's mobility.
If the brake switch is worn out, it's better to replace it with a new one. The price of a brake switch is also quite affordable. You just need to find a brake switch that matches your car type.
Damage to the gearbox
Another symptom of damage to the automatic car's transmission can be felt when the gear lever successfully shifts, but when accelerating, it feels heavy. This can indicate a failure in gear shifting.
This problem arises due to damage to the gearbox cable, either broken or possibly frayed. As a result, even though the lever has been operated, the gear shifting does not occur. Immediately take your beloved car to your trusted workshop for further inspection.
The most important thing for automatic car owners is to perform regular maintenance. Problems will become more complicated if the car owner does not carry out routine maintenance. The vehicle's performance can become suboptimal and may even lead to more extensive damage.
