  1. Start the engine and allow the engine to idle until the transmission fluid temperature has reached the value specified.
  2. Depress the brake pedal and move the shift lever through the gear ranges, pausing a few seconds in each range. Return the shift lever to the PARK range.

    Notice: Refer to Transmission Fluid Vent Cap Removal Notice in the Preface section.

  3. Remove the fluid vent cap.
  4. Raise the vehicle on a hoist. The vehicle must be level, with the engine running and the shift lever in the PARK range. Refer to Lifting and Jacking the Vehicle.

    Caution: The engine must be running when the transmission fluid fill plug is removed, or excessive fluid loss will occur. Transmission fluid may be hot. Since the actual fluid level is unknown, stand clear when removing the fill plug. Have a container ready to capture any lost fluid. Do not turn the engine off with the fill plug removed, as you can be injured by hot transmission fluid being expelled out of the oil fill opening.

  5. Remove the transmission oil level control plug (65). See drawing above.

    Important: The transmission fluid may darken with normal use and does not always indicate contamination or oxidation.

  6. Check the fluid color. If necessary, use a small screwdriver as a dipstick.

Is the fluid color clear red or light brown with no burnt odor?

At least 40°C (104°F)

Add DEXRON®VI automatic transmission fluid in increments of 0.5 L (0.5 qt) until the fluid drains from the plug hole.

Did you add more than 1.5 L (1.6 qt) to the transmission?

  1. Repair the transmission if required. In some cases, overhaul may be required.
  2. Flush the transmission oil cooler and pipes and check flow. Refer to Transmission Fluid Cooler Flushing and Flow Test.

    Notice: Refer to Transmission Fluid Vent Cap Removal Notice in the Preface section.

  3. Remove the fluid vent cap.
  4. Add enough DEXRON®VI automatic transmission fluid to bring the fluid level to the bottom of the threaded plug hole.
  5. Start the engine and allow the engine to idle until the transmission fluid temperature has reached the value specified.
  6. Depress the brake pedal and move the shift lever through the gear ranges, pausing a few seconds in each range. Return the shift lever to the PARK range.
  7. Raise the vehicle on a hoist. The vehicle must be level, with the engine running and the shift lever in the PARK range. Refer to Lifting and Jacking the Vehicle.

    Caution: The engine must be running when the transmission fluid fill plug is removed, or excessive fluid loss will occur. Transmission fluid may be hot. Since the actual fluid level is unknown, stand clear when removing the fill plug. Have a container ready to capture any lost fluid. Do not turn the engine off with the fill plug removed, as you can be injured by hot transmission fluid being expelled out of the oil fill opening.

  8. Remove the transmission plug.
  9. If needed, add DEXRON®VI automatic transmission fluid in increments of 0.5 L (0.5 qt) until the fluid drains from the threaded plug hole.

    Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

    Important: Before installing the fill plug, apply GM P/N 12345382 (Canadian P/N 10953489) to the thread of the line pressure plug.

  10. Allow fluid to finish draining out of the plug hole. Install the plug and tighten to specified value.
  11. Wipe any excess fluid from the transmission with a rag or shop towel.
  12. Install the fluid vent cap.
