How to Check Car Automatic Transmission
Introduction
The automatic transmission is a complex system that allows the car to shift gears without the driver having to manually operate a clutch. It is a very convenient feature, but it can also be expensive to repair if it breaks down. Therefore, it is important to know how to check the transmission on your car so that you can catch any problems early and get them fixed before they become major issues.
Checking the Transmission Fluid
The first step in checking the transmission is to check the fluid level. The transmission fluid is a special type of oil that lubricates the gears and other moving parts. It is important to keep the fluid at the correct level, as too much or too little fluid can cause problems.
To check the transmission fluid, you will need a dipstick. The dipstick is usually located near the engine, and it will have a handle that you can pull out. Pull out the dipstick, wipe it clean, and then reinsert it into the transmission. Pull it out again and check the level of the fluid. The fluid level should be between the two marks on the dipstick.
If the fluid level is low, you will need to add some fluid. You can usually find the correct type of fluid for your car at your local auto parts store. To add fluid, simply remove the dipstick and pour the fluid into the dipstick tube. Be careful not to overfill the transmission, as this can also cause problems.
Checking the Transmission Filter
The transmission filter helps to keep the transmission fluid clean. It is a good idea to change the filter every 30,000 to 50,000 miles. To change the filter, you will need to locate the transmission pan. The transmission pan is usually located on the bottom of the transmission, and it is held in place by a few bolts.
Once you have located the transmission pan, remove the bolts and carefully remove the pan. Be careful not to spill any fluid. The transmission filter is usually located inside the pan, and it is held in place by a few bolts. Remove the bolts and remove the filter.
Clean the transmission pan and the new filter with a clean rag, and then reinstall the filter and the pan. Tighten the bolts to the correct torque specifications.
Checking the Transmission Gears
The next step is to check the transmission gears. To do this, start the car and put it in drive. Slowly accelerate and listen for any noises. If you hear any grinding or clunking noises, it is a sign that the transmission gears are worn or damaged.
You can also check the transmission gears by driving the car up a hill. If the car hesitates or struggles to climb the hill, it is a sign that the transmission gears are not working properly.
Checking the Transmission Control Module
The transmission control module is the computer that controls the transmission. It is responsible for shifting gears, and it can also detect problems with the transmission. To check the transmission control module, you will need a scan tool.
Connect the scan tool to the car’s diagnostic port and turn on the ignition. The scan tool will display a list of codes, which are used to diagnose problems with the car. If there are any codes related to the transmission, you will need to take the car to a mechanic to have them diagnosed and repaired.
Conclusion
Checking the transmission on your car is a relatively simple process that can help you catch any problems early and get them fixed before they become major issues. By following these steps, you can help keep your car running smoothly for years to come.
