Chevy vehicles vary by year, model, and transmission type, so the process is not always the same. This guide explains how to check transmission fluid in both older and newer Chevy vehicles, including those without a dipstick.
How to Check Transmission Fluid Chevy
To check transmission fluid in a Chevy, first park the vehicle on level ground and warm the engine to operating temperature, then cycle through all gears before returning to Park; if your Chevy has a transmission dipstick, remove it, wipe it clean, reinsert fully, and check that the fluid level is between the marked range while inspecting the fluid for a clean red or light pink color and no burnt smell.
If your Chevy has a sealed transmission with no dipstick, the fluid must be checked from underneath by removing the transmission check plug with the engine running, where a small steady drip indicates the correct level and no fluid means it is low; manual Chevy transmissions are checked by removing the fill plug and ensuring fluid is level with the bottom of the opening, and in all cases.
Identify Your Chevy Transmission Type
Before checking the fluid, you need to know whether your Chevy has:
- An automatic transmission with a dipstick
- A sealed automatic transmission with no dipstick
- A manual transmission
Most older Chevy models (generally pre-2010) have a transmission dipstick. Many newer models use sealed transmissions that require checking fluid from underneath the vehicle. Manual transmissions use a different checking method altogether.

How to Check Transmission Fluid in a Chevy With a Dipstick
If your Chevy has a dipstick, this is the simplest method.
Step 1: Park on Level Ground
Make sure the vehicle is parked on a flat surface. Set the parking brake firmly.
Step 2: Warm Up the Engine
Start the engine and let it idle for about 5–10 minutes. Transmission fluid expands when warm, and Chevy specifies checking the fluid at operating temperature.
Step 3: Cycle Through the Gears
With your foot on the brake, shift through all gears, Park, Reverse, Neutral, Drive, and Low, then return to Park. This allows fluid to circulate through the transmission.
Step 4: Locate the Transmission Dipstick
Open the hood and locate the transmission dipstick. It is usually marked with a red or yellow handle and labeled “Transmission.”
Step 5: Check the Fluid Level
Pull out the dipstick, wipe it clean with a lint-free cloth, then reinsert it fully. Pull it out again and check the fluid level. The fluid should be between the “Hot” or “Full” markings.
Step 6: Inspect Fluid Condition
Healthy transmission fluid is typically red or light pink and has a clean, fresh smell. Dark brown or black fluid, or a burnt odor, indicates contamination or overheating and may require service.

How to Check Transmission Fluid in a Chevy Without a Dipstick
Many modern Chevy vehicles, including models like Silverado, Equinox, Malibu, and Traverse, have sealed transmissions.
Step 1: Safely Raise the Vehicle
Use a jack, jack stands, or a vehicle lift. Always follow safety procedures before going underneath your Chevy.
Step 2: Warm the Transmission
Start the engine and allow it to reach operating temperature. Some Chevy models require the transmission fluid temperature to be within a specific range for an accurate reading.
Step 3: Locate the Check Plug
Under the vehicle, locate the transmission fluid check plug. It is usually on the side or bottom of the transmission pan.
Step 4: Remove the Plug
With the engine running, carefully remove the check plug. If fluid slowly drips out, the level is correct. If no fluid comes out, the level is low.
Step 5: Reinstall the Plug
Once the check is complete, reinstall and tighten the plug to factory specifications.
Because sealed transmissions require precision and often special tools, many Chevy owners prefer to have this procedure done by a professional.

How to Check Transmission Fluid in a Manual Chevy
Manual transmissions do not use a dipstick.
- Park the vehicle on level ground and turn off the engine.
- Raise the vehicle safely.
- Locate the fill plug on the transmission housing.
- Remove the plug. The fluid should be level with the bottom of the hole.
- If fluid is low, add the correct type until it reaches the opening.
What Fluid Should You Use?
Always use the transmission fluid specified in your Chevy owner’s manual. Common Chevy automatic fluids include Dexron-VI, while manual transmissions often require specific gear oils. Using the wrong fluid can cause shifting problems and internal damage.

How Often Should You Check Transmission Fluid?
For dipstick-equipped Chevy vehicles, checking every 30,000 miles or during oil changes is recommended. Sealed transmissions should still be inspected periodically, especially if you notice shifting issues, fluid leaks, or warning lights.
Signs Your Chevy Needs Transmission Fluid Service
- Delayed or rough shifting
- Slipping gears
- Transmission overheating
- Grinding noises
- Burnt smell
- Fluid leaks under the vehicle
If you notice any of these symptoms, check the fluid immediately or consult a professional.
Final Thoughts
Knowing how to check transmission fluid in your Chevy helps prevent major transmission problems and keeps your vehicle running smoothly. Whether your Chevy has a traditional dipstick or a sealed system, regular inspections and using the correct fluid are key to long-term reliability. If you’re unsure about the process or fluid type, consulting a qualified technician is always the safest option.
