How To Check Transmission Fluid On 2020 Chevy Silverado

As we have said earlier, transmission fluid may become low in quantity if you drive your vehicle frequently. And when it gets low, you may have trouble with gear shifting, unwanted noises when you drive. 

No one wants to face such things when they drive. So, checking the transmission fluid level every once in a while is necessary. If you need some clarification about how to do this correctly, here’s a detailed guide for you. Just follow these steps, and you will have your job done. 

1. Start the Engine 

You can only check the car’s transmission fluid level if your car’s engine is running. So, first, start the car and let the engine warm up decently. 

2. Raise the Temperature to Appropriate Level

The engine should be warm enough after a few minutes of starting the car. Now, check the temperature of the transmission fluid. Go to the driver’s information center just behind the steering wheel, and you will find a knob on the right side. 

Turn the knob to go through different menu items and stop when you find transmission fluid temperature. The temperature should be between 80-90°F to have a correct reading of transmission fluid level. 

If the temperature is way high, idling the vehicle will turn it down. And if it is below 80°F, wait another few minutes for the running engine to warm up the fluid. 

3. Find the Dipstick

Once the fluid is up to the right temperature, pop the hood of your Chevy Silverado and find the dipstick there. In most models, it should be at the right or behind the oil dipstick, towards the car’s windshield. 

4. Insert the Dipstick into The Fluid Chamber 

Remove the dipstick from its place and insert it into the transmission fluid chamber. Remember to wipe the dipstick clean before inserting it into the tube. Keep the dipstick there for a few seconds before bringing it out. 

5. Check the Fluid Level 

The transmission fluid dipstick has several markings. The first lines are called cold marks, and the lines above them are hot marks. After removing the dipstick from the fluid chamber, check at which level the fluid has come up. 

As we are checking the fluid at an 80-90°F temperature level, the liquid on the dipstick should be up to the first lines. 

6. Inspect the Fluid 

Now, after checking the level, wipe the dipstick with a clean cloth or rag and see the color of the transmission fluid. If it gives a pinkish hue, your transmission fluid is all good. But if it is brown, black, or any color different from pink, it becomes dirty. It is time to change the fluid. 

7. Check Again In Warm Temperature

It is better to check transmission fluid on two different temperature levels, cold and hot. We have already checked the fluid at a cold level, which is at 80-90°F. Now, we will check it at the raised temperature. 

Drive the car a little bit around until the transmission fluid temperature rises to 160-200°F. Once the temperature is at the desired level, do the same steps, 4 to 6, to check the fluid level. 

The transmission fluid level should be up to the upper hot marks this time. If it doesn’t come up to this marking, it indicates that the transmission fluid is low, and you should add more fluid.

2020 Silverado Transmission Fluid Check Without Dipstick

A few models of Silverado don’t come with a dipstick. How do you check the transmission fluid level on those vehicles? We will tell you how to do that. 

1. Start the Car

You have to start your car’s engine whenever you are checking the transmission fluid level. It is necessary for the engine to be running to start all the transmissions. 

2. Raise the Temperature 

It is inappropriate to check the transmission fluid level if it is not up to the right temperature. To cold check, wait a few minutes after starting the engine. And for hot check, drive the car at 1st or 2nd gear to raise the temperature. 

3. Open the Inspection Plug

Automobiles with no dipstick to check for transmission fluid are said to have a sealed transmission system. They have an inspection plug at the base of the fluid chamber and a fill-in plug at the upper side to fill it. 

You have to open the inspection plug to check the fluid level. You may need the range to do so. 

4. Check the Fluid

After opening the inspection plug, if nothing comes out, open the fill-in plug and add some fluid inside. When the fluid starts dribbling out, stop and wait for the fluid to stop dribbling. 

Check the fluid with a cloth to see its color. If it’s any other color than a pink hue, it is time to change the fluid. 

How Often Should You Check Transmission Fluid?

It depends on how often you drive. If you drive frequently, almost every day, it is better to check the transmission fluid every once a month. Dirt and debris can accumulate in the transmission fluid and become polluted. And it can slow down your car with slipping gears and other associated problems. That’s the last thing you want, right?

When Should You Change The Transmission Fluid?

When the transmission fluid is low or dirty, you will know it by your vehicle’s performance. It will show some signs like:

  • Slipping gears.
  • Having difficulty in changing gear.
  • Improper acceleration or no acceleration at all.
  • Strange noises.
  • Delayed response when you try to put the car into reverse.

When you see these signs, it is better to check the transmission fluid before considering any other cause. 

Things To Know About Transmission Fluid 

Transmission fluid is an essential part of the vehicle’s internal system. Can you use any fluid in your vehicle? Of course not! The fluid must be compatible with the car. Else it may cause multiple problems. Here are some things that you should know before putting any fluid in your Chevy Silverado. 

  • Every car has a particular transmission fluid mentioned in its manual. It is compatible with the car’s internal system. Other liquids may harm the system. So you should be stuck to using the suggested fluid only. 
  • Too much or too little transmission fluid harms the car’s operation. You have to keep the fluid at a proper level by checking it with the dipstick. 
  • Changing the transmission fluid after every 50,000 to 1,00,000 miles driving is better. 
  • Slow gear changing is the most common sign of insufficient or polluted transmission fluid.
