Check transmission fluid levels
Checking your transmission fluid levels is an important part of car maintenance. It can help prevent unexpected breakdowns and costly repairs. Here’s a detailed guide on how to check the transmission fluid levels in your automatic transmission car:
Locate the Dipstick:
The transmission fluid dipstick is usually located near the oil dipstick. In front-wheel-drive vehicles, it’s often found to the right of the oil dipstick, while in rear-wheel-drive vehicles, it’s typically near the rear of the engine. Refer to your car’s owner’s manual if you need help locating it.
Prepare the Car:
Park your car on a level surface and turn on the engine. Let the engine run for a few minutes to warm up. This is important because transmission fluid expands with heat, and checking the level under normal operating conditions will give you accurate results.
Check the Fluid Level:
Once the engine is warmed up, leave the car idling in park. Locate the transmission fluid dipstick, and before removing it, wipe around the dipstick area with a clean cloth to prevent dirt from entering the gearbox. Now, remove the dipstick and wipe it clean with a non-fluffy cloth. Reinsert the dipstick gently, and then withdraw it immediately to check the fluid level.
Inspect the Fluid:
Check the transmission fluid on the dipstick for its level, color, and condition. The fluid level should be between the “‘full'” and “‘low'” or “‘fill'” marks on the dipstick. The color of the fluid can also indicate its health. Most new transmission fluids are bright red or have a pink hue. If the fluid is dark red, light brown, or black, it may be time for a change. Additionally, look for specks of dirt or metal in the fluid, as these indicate wear and may require expert attention.
Top Up Fluid if Necessary:
If the fluid level is low, you can top it up through the dipstick tube, using a small funnel. Add a little fluid at a time and check the level frequently to avoid overfilling. Always use the type of transmission fluid recommended in your car’s handbook or service manual.
It’s important to note that some newer cars may not have a transmission dipstick, making it impossible to check the fluid level at home. In such cases, an automotive repair professional will need to check the fluid level. Additionally, remember to clean the sump pan and cooling grille regularly to prevent them from being heavily coated with mud or road dirt, which can cause issues.

Check for faulty transmission position sensor
The transmission position sensor, also known as the transmission range sensor, is an electronic sensor that provides a position input to the Powertrain Control Module (PCM). This allows the PCM to control the transmission according to the position commanded by the sensor.
A failing transmission position sensor may no longer send the right signals to the PCM. Without signals from the position sensor, the PCM will not know when to shift the transmission’s gears. This can result in the car failing to move out of park or neutral, or the transmission shifting into the wrong gear.
To check for a faulty transmission position sensor, you can perform the following steps:
- Park your vehicle on a flat, hard surface and secure the wheels with chocks. Ensure the transmission is in park mode and engage the parking brake.
- (Optional) Install a nine-volt battery saver into your cigarette lighter to keep your computer live during the process.
- Disconnect the car’s battery. Open the vehicle’s hood and disconnect the battery.
- Locate the transmission position sensor. It is usually located on the car’s automatic transmission. You may need to go under the vehicle and use a flashlight to find it.
- Place the shifter into a gear and attempt to start the engine. If the engine starts with the transmission in gear, then the sensor has likely failed.
- If the sensor is faulty, you will need to replace it. This typically involves removing the harness and mounting bolts securing the sensor to the transmission, cleaning the harness connector, and installing a new sensor.
It is important to note that a failing transmission position sensor can cause serious problems with your vehicle’s transmission and may require professional repair or replacement. Some modern vehicles are equipped with failsafe devices that prevent the transmission from shifting gears if a problem is detected, which can help protect your car from further damage. If you are unsure or uncomfortable performing these checks and repairs yourself, it is recommended to consult a mechanic or automotive technician for assistance.

Check for dirty transmission fluid
Checking for dirty transmission fluid is an important aspect of car maintenance. While it is true that transmission fluid does not need to be changed as frequently as engine oil or brake fluid, neglecting it can result in costly repairs. Here are some detailed steps and information to help you check for dirty transmission fluid in your automatic transmission car:
Firstly, it is important to understand the role of transmission fluid. Transmission fluid is responsible for lubricating the numerous moving metal parts in the transmission system, reducing friction and preventing wear and tear. It also assists in cooling the system by regulating temperature and acts as a hydraulic fluid, making gear changes smoother.
Now, to identify if your transmission fluid is dirty, there are several warning signs to look out for. One of the most common signs is difficulty shifting gears. If your car hesitates or takes a second too long to engage when shifting into drive or reverse, it could be an indication of low or dirty transmission fluid. Additionally, if your vehicle randomly lunges or surges forward, it could be a sign that your transmission fluid is contaminated or dirty. Contaminants can block the fluid flow, impacting the transmission’s performance.
Another sign to listen out for is unusual noises. If you hear any unnerving or unusual grinding noises, it could be an indication that your transmission fluid has degraded and needs to be changed. These noises occur when the fluid loses its lubricating properties, causing the metal parts to grind against each other. Additionally, any foul or burning smells coming from your car could be a sign of overheated transmission fluid, which may be due to low fluid levels.
Finally, it is important to maintain your transmission fluid properly. Unlike motor oil, transmission fluid levels should remain consistent throughout the lifespan of the car. However, it is still essential to have it flushed and replaced regularly as part of your car’s maintenance schedule. Driving on old, contaminated fluid can be harmful to your vehicle and lead to more serious issues.
