    Important: Transmission fluid level can only be accurately checked when the fluid temperature is between 30-50°C (86-122°F).

  1. Start the engine.
  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.
  3. Raise the vehicle on a hoist. The vehicle must be level with the engine running and the shift lever in the PARK range.
  4. Remove the transmission fluid level hole plug (36). Location is model dependent. See the drawing above for locations.
  5. Important: The transmission fluid may darken with normal use and does not always indicate contamination or oxidation.

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

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

Let the fluid temperature rise until it has reached the specified value. Inspect the fluid level. The level should be even with the bottom of the threaded plug hole.

Is the fluid level low?

30-50°C (86-122°F)

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

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

  1. Drain the fluid by removing the transmission fluid pan drain plug (63).
  2. Remove the transmission fluid pan.

     

  3. Important: A very small amount of material in the bottom of the pan is a normal condition.

  4. Inspect the bottom pan for any excessive debris.

Was excessive debris found?

  1. Repair the transmission, if required.

    Important: If the transmission is overhauled, it may be necessary to flush the transmission fluid cooler and pipes.

  2. Add enough DEXRON®VI automatic transmission fluid to bring the fluid to the fluid level to the bottom of the threaded plug hole.

  3. Start the engine.
  4. 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.
  5. Raise the vehicle on a hoist. The vehicle must be level with the engine running and the shift lever in the PARK range.

     

  6. 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.

  7. Let the AT fluid temperature rise until it has reached the specified value. Remove the transmission plug.
  8. If needed, add DEXRON®VI automatic transmission fluid in increments of 0.5 L (0.5 qt) until the fluid drains from the threaded hole plug.

     

  9. Important: If the level hole plug (36) and O-ring (37) are not damaged, they should be reused.

  10. Allow fluid to finish draining out of the plug hole. Inspect the level hole plug (36) and O-ring (37) for damage. Install the transmission hole plug (36) and tighten to the specified value.
  11. Wipe any excess fluid from the transmission with a rag or shop towel.
