Changing your 2017 Chevy Traverse transmission fluid can improve performance and extend the life of your transmission. This guide provides a step-by-step walkthrough of a partial fluid change, perfect for DIY maintenance. While this process doesn’t replace all the fluid, it refreshes a significant portion and is easier to perform than a full flush.
Partial Fluid Change Procedure
This process focuses on draining and replacing approximately 5 quarts of transmission fluid. Remember, this is a partial change, as some fluid remains in the torque converter, cooler lines, and other components.
Materials Needed
Before you begin, gather the following:
- Dexron VI Transmission Fluid: Approximately 5-6 quarts.
- Drain Pan: A large container (at least 5 quarts) to collect the old fluid.
- Wrench or Socket: 7/16″ to remove the drain plug.
- Funnel: A long-necked funnel to easily pour new fluid into the transmission.
- Plastic Sheeting and Cardboard: To protect your work area and make cleanup easier.
- Shop Rags or Paper Towels: For cleaning up spills.
- Gloves: To protect your hands.
Step-by-Step Instructions
- Prepare Your Vehicle: Park your Traverse on a level surface, engage the parking brake, and allow the engine to cool down slightly. Warm fluid drains more easily, but avoid working with excessively hot fluid.
Preparing for the transmission fluid change
-
Locate the Drain Plug: The transmission drain plug is typically located on the bottom of the transmission pan. Refer to your owner’s manual for the exact location. Place your drain pan beneath the plug.
-
Drain the Fluid: Carefully remove the drain plug using a 7/16″ wrench or socket. Allow the fluid to drain completely. This may take some time. You can also remove the transmission dipstick to allow for faster draining. Observe the old fluid for any metal shavings or debris, which could indicate more serious transmission problems.
-
Inspect the Drain Plug: Check the condition of the drain plug and its gasket.
-
Replace the Drain Plug: Once the fluid has finished draining, reinstall the drain plug. Tighten it to the manufacturer’s specified torque (consult your owner’s manual).
-
Add New Fluid: Using the funnel, carefully pour the correct amount of new Dexron VI transmission fluid into the transmission dipstick tube. The owner’s manual will specify the correct amount for a drain and fill.
-
Check the Fluid Level: With the engine running and the transmission in park, check the fluid level using the dipstick. Add more fluid if necessary to reach the “full” mark on the dipstick.
-
Dispose of Old Fluid Properly: Take the used transmission fluid to a local auto parts store or recycling center for proper disposal.
Important Considerations
- Fluid Capacity: Consult your 2017 Chevy Traverse owner’s manual for the precise fluid capacity and recommended fluid type.
- Fluid Color and Smell: Pay attention to the color and smell of the old fluid. Dark brown or burnt-smelling fluid could indicate the need for a more extensive transmission service.
- Regular Maintenance: Performing a partial transmission fluid change every 30,000-60,000 miles, depending on your driving conditions, can significantly extend the life of your transmission. Severe driving conditions, such as frequent stop-and-go traffic, may require more frequent changes.
This guide provides a general overview. Always consult your owner’s manual for specific instructions and recommendations for your 2017 Chevy Traverse. If you’re unsure about any step, consult a qualified mechanic.
