How to Check Transmission Fluid on a 2020 Silverado
The 2020 Chevy Silverado’s 8-speed and 10-speed automatic transmissions are sealed units with no dipstick — checking the fluid requires a lift, the fluid at a specific temperature, and a check plug, which is why GM recommends this be done by a dealer or professional rather than as a driveway DIY task. — see our related guide, Can I Take My Chevy to Any Dealer for Service?.
There’s no dipstick to locate on this transmission — looking for one near the engine bay will come up empty. Instead, GM says there’s normally no reason to check ATF level on the 8-speed or 10-speed automatic unless there’s an evident leak. If a leak is suspected, checking the level correctly requires the truck on a lift and level, the fluid warmed to a specific temperature, and a check plug removed — fluid should just barely dribble out if the level is correct.
Because of the temperature and lift requirements, this is genuinely a job best left to a dealer or qualified mechanic rather than a home dipstick check. Regularly having the transmission fluid inspected ensures optimal performance and longevity of the vehicle’s transmission system.
Step-by-step Guide: How To Check Transmission Fluid On A 2020 Chevy Silverado
Welcome to our step-by-step guide on how to check transmission fluid on a 2020 Chevy Silverado. Regularly checking your transmission fluid is essential to maintaining the performance and longevity of your vehicle’s transmission. This simple process can help you identify any potential issues early on and avoid costly repairs in the future. So let’s get started and ensure your Silverado’s transmission is in top shape!
Step 1: Park The Vehicle On Level Ground
The first step in checking your transmission fluid is to park your 2020 Chevy Silverado on a level surface. This is important to ensure an accurate reading of the fluid level. Find a flat area like a driveway or parking lot where the vehicle will remain steady throughout the process.
Step 2: Turn Off The Engine And Let It Cool
Next, make sure the engine is turned off and allow it to cool down. It is crucial to check the transmission fluid when the engine is cool to prevent any burns or injuries. Wait for at least 10 minutes to ensure the engine has cooled down before proceeding to the next step.
Step 3: Confirm There Is No Dipstick
Before doing anything else, confirm what you’re working with: the 2020 Silverado’s 8-speed and 10-speed automatics are sealed transmissions, so there’s genuinely no dipstick handle to find under the hood. If you’ve been searching the engine bay without success, that’s expected — move on to understanding the real check procedure below rather than continuing to look for one.
Step 4: Warm the Fluid to the Correct Temperature
Instead of wiping a dipstick, the real procedure starts by warming the transmission fluid to the correct temperature range — typically done by driving the truck — since the check plug method only gives an accurate reading within a specific temperature window. This is one of the reasons GM recommends leaving this to a professional with the right equipment to verify fluid temperature accurately.
Step 5: Have the Check Plug Removed on a Lift
With the fluid at the correct temperature and the truck level on a lift, a technician removes the check plug on the transmission itself. This is the step where a lift genuinely matters — the truck needs to be level and raised enough to safely access the plug, which isn’t practical in a home driveway. This confirms the actual transmission fluid level far more precisely than a dipstick reading ever could.
Step 6: Watch for Fluid at the Check Hole
With the check plug removed, a properly filled transmission will let a small amount of fluid dribble out of the hole — that’s the sign the level is correct. If nothing comes out, the level is low and fluid needs to be added; if fluid pours out steadily rather than dribbling, the transmission may be overfilled. There are no marks to read the way there would be on a traditional dipstick — the dribble itself is the indicator.
Step 7: Add Or Replace Fluid If Necessary
Finally, based on whether fluid dribbled from the check hole in the previous step, determine if the fluid level is within the acceptable range. If the fluid level is low or below the minimum mark, you’ll need to add transmission fluid. On the other hand, if the fluid is dark, discolored, or smells burnt, it may indicate a need for fluid replacement. In such cases, it’s recommended to consult your vehicle’s owner’s manual or a qualified mechanic for further guidance.
Congratulations! You’ve successfully checked the transmission fluid on your 2020 Chevy Silverado. Regularly performing this simple task will help prolong the life of your transmission and ensure optimal performance. Remember, if you’re unsure about any step or have concerns about your transmission’s condition, it’s always best to seek professional assistance.

Tips And Precautions
Here’s how to check the transmission fluid on your 2020 Chevy Silverado. Follow these easy steps to ensure your vehicle runs smoothly and efficiently.
Understanding Fluid Level Indicators |
When it comes to keeping your 2020 Chevy Silverado in top shape, checking the transmission fluid regularly is essential. Transmission fluid acts as a lubricant, ensuring smooth gear changes and preventing overheating. In this section, we will provide you with valuable tips and precautions to help you check the transmission fluid effectively and keep your vehicle running smoothly.
Signs Of Low Or Contaminated Transmission Fluid |
Before diving into the actual process of checking transmission fluid, it’s crucial to understand the signs of low or contaminated fluid. Ignoring these signs can lead to significant transmission problems down the road. Keep an eye out for the following warning signals:
- Difficulty shifting gears or delayed engagement
- Burnt smell or discoloration of the fluid
- Leaking fluid underneath the vehicle
- Whining or humming noise during gear changes
If you observe any of these signs, it’s recommended to bring your Chevy Silverado to a professional mechanic for a proper diagnosis and potential fluid replacement.
Common Mistakes To Avoid When Checking Transmission Fluid |
While checking the transmission fluid may seem like a simple task, there are a few common mistakes that many people make. Avoid these pitfalls to ensure an accurate assessment:
- Assuming all transmission fluid is the same: Every vehicle has specific transmission fluid requirements, so it’s essential to use the recommended type and grade for your Chevy Silverado.
- Checking fluid levels in cold conditions: Transmission fluid expands and contracts with temperature changes. To get an accurate reading, ensure the engine is warm and running.
- Not consulting the owner’s manual: Each vehicle has its own way of checking transmission fluid. Always refer to the owner’s manual for the correct procedure.
- Overfilling or underfilling fluid: It’s crucial to achieve the correct fluid level. Overfilling can lead to foam and inadequate lubrication, while underfilling can result in excessive heat.
- Ignoring regular fluid maintenance: Checking fluid levels is just a part of transmission maintenance. Regular fluid changes, as recommended by the manufacturer, will help extend the life of your transmission.
Conclusion
To sum up, checking the transmission fluid on your 2020 Chevy Silverado is a straightforward task that ensures your vehicle performs optimally. By following the steps provided in this guide, you can easily maintain the proper fluid level and prevent potential transmission issues down the road.
Regularly checking your transmission fluid is a crucial part of vehicle maintenance, allowing you to extend the lifespan of your Silverado and enjoy a smooth driving experience. Keep your transmission running smoothly by staying on top of your fluid levels.
