Gather the Required Materials

Before you begin, it’s important to gather all the necessary materials and tools. Here are the items you will need:

  • Transmission fluid: Check your vehicle’s owner’s manual to determine the type and quantity of transmission fluid required.
  • Drain pan: A drain pan will be used to collect the old transmission fluid.
  • Ratchet and socket set: You will need a ratchet and socket set to remove the transmission fluid pan.
  • Gasket or sealant: Depending on your vehicle, you may need a new gasket or sealant for the transmission fluid pan.
  • Torque wrench: A torque wrench will be needed to tighten the transmission fluid pan bolts to the specified torque.
  • Funnel: A funnel will help you pour the new transmission fluid into the transmission.
  • Disposable gloves and safety glasses: It’s important to protect yourself by wearing disposable gloves and safety glasses throughout the process.

Locate the Transmission Fluid Pan

To access the transmission fluid pan, you will need to raise your Chevy Silverado 1500 using a jack and secure it with jack stands. Once the vehicle is safely elevated, locate the transmission fluid pan, which is typically located underneath the vehicle towards the rear.

Drain the Old Transmission Fluid

Place the drain pan underneath the transmission fluid pan to catch the old fluid. Use a ratchet and socket to remove the bolts securing the transmission fluid pan. Slowly lower the pan, allowing the old fluid to drain into the drain pan. Once the fluid has drained, remove the gasket or clean off the old sealant from the pan and transmission.

Replace the Transmission Fluid Filter (if applicable)

Some Chevy Silverado 1500 models have a transmission fluid filter that needs to be replaced during a fluid change. If your vehicle is equipped with a filter, carefully remove it and replace it with a new one. Be sure to follow the manufacturer’s instructions for proper installation.

Clean the Transmission Fluid Pan

Thoroughly clean the transmission fluid pan using a suitable cleaner to remove any residue or debris. Inspect the pan for any signs of damage or excessive wear. If necessary, replace the pan to ensure a proper seal.

Install the Transmission Fluid Pan

Apply a new gasket or sealant to the transmission fluid pan, ensuring proper alignment. Carefully lift the pan back into place and hand-tighten the bolts. Use a torque wrench to tighten the bolts to the specified torque as per the manufacturer’s recommendations.

Refill with New Transmission Fluid

Using a funnel, pour the recommended amount of new transmission fluid into the transmission through the transmission fluid dipstick tube. Be sure to use the correct type of fluid as specified in your vehicle’s owner’s manual. It’s important to pour the fluid slowly to avoid overfilling.

Check the Transmission Fluid Level

Start the engine and let it idle for a few minutes to allow the transmission fluid to circulate. With the engine still running, check the transmission fluid level using the dipstick. Add more fluid if necessary to bring it to the appropriate level. Be cautious not to overfill.

Dispose of the Old Fluid

Properly dispose of the old transmission fluid in accordance with local regulations. Many auto parts stores and service centers accept used fluids for recycling.


Changing the transmission fluid in your Chevy Silverado 1500 is a relatively straightforward process that can be done with basic tools and materials. By following the steps outlined in this article, you can ensure the proper maintenance of your vehicle’s transmission system, promoting its longevity and smooth operation.
