6 Ways to Fix a Broken Automatic Car Transmission

Is your automatic car transmission broken? Don't worry, how to fix an automatic car transmission is very easy. Check out the guide below.

Recently, automatic cars in Indonesia have been in demand by many people because they are considered easier to operate, especially for women and those who are still learning to drive.

Although they are considered to make driving easier, automatic cars often experience problems with their transmission.

There are several factors and causes for automatic car transmissions to frequently jerk, break, and become damaged. For example, neglecting to change transmission oil, to mistakes made while operating the car's transmission.

So, how can you tell if your automatic car transmission is damaged? And how can you properly address it? Follow the complete information below.

Signs of a Damaged Automatic Car Transmission

Before discussing how to fix it, you should first check the signs of problematic car transmission. This is so you can understand how severe the damage is and know how to handle it correctly.

1. Producing Strange Noises When Shifting the Transmission Lever

When you shift the transmission lever from P to R or from N to D, it should normally not produce a "crack" or "crunching" sound.

If it starts making strange noises when shifting the transmission lever, it indicates that there is damage to the automatic transmission system.

2. Hesitation and Heavier Acceleration

When you press the gas pedal and release the brake pedal, if there is a slight jolt or the engine vibrates, it is likely that there is damage to the TCM speed sensor or electric automatic transmission pressure solenoid.

It could also be caused by an oil leak in the engine affecting the conventional automatic transmission, making the car feel sluggish or the acceleration heavier.

3. Vibrating While Driving

If you feel unusual vibrations while driving your car, this could also be a sign that your automatic car transmission is damaged.

4. Increased Fuel Consumption

If you feel that your car is consuming more fuel than before, it could be because the engine's torque is unable to deliver energy to the wheels optimally.

This causes the engine to work harder to produce revolutions, resulting in higher fuel consumption.

How to Fix a Broken Automatic Car Transmission

After you know the signs that your automatic car transmission is about to break, here are some steps you can take to address the problematic automatic car transmission:

1. Reset the ECU

The first step you can take is to reset the ECU. If you are not familiar with what the ECU is and how to reset it, you can check our previous post here Understanding the Electronic Control Unit (ECU) in Cars.

2. Clean the Car's Valve Body

The next way to fix a damaged automatic car transmission is to clean the car's valve body. If you have reset the ECU but did not get results, you can clean the car's valve body.

3. Change the Automatic Car Oil

Next, if the valve body has been thoroughly cleaned, you can proceed to change the oil. Make sure to choose the best automatic car oil that meets the specifications recommended for your automatic car.

4. Drain the Automatic Transmission Oil

If the previous steps have been taken but did not work, you can drain the automatic transmission oil until it is clean. You can ask for help from a professional technician to assist in the draining process to ensure the transmission system is free from dirt deposits.

5. Remove Transmission Components

You can remove the front cover of the transmission one by one slowly, starting from the planetary gear, clutch, to the brake unit.

6. Clean the Transmission Components

Clean all transmission components. First, observe all the transmission components thoroughly before disassembly. Then overhaul to find the cause of the transmission damage.

These are the steps you can take. Make sure to also perform regular car maintenance to avoid such issues.

You can periodically change the transmission oil; if the engine oil has changed color to a darker shade, immediately proceed with the replacement.

Ensure that the oil is not leaking. You can also visit an official Daihatsu workshop for professional car maintenance to prevent more severe damage. Hopefully, the methods for fixing automatic car transmissions above will be beneficial.
