  5. Install the transmission fluid filter, pan gasket and pan. For additional information, refer to Fluid Pan, Gasket and Filter  in this article.
  6. CAUTION: The use of any other transmission fluid than specified can result in the transmission failing to operate in a normal manner or transmission failure.
  7. Fill the transmission.
    • Add 7.0L (7.5 qt) of clean automatic transmission fluid to the transmission through the fluid filler tube.
  8. Start the engine. Move the transmission range selector lever through all the gear ranges, checking for engagements.
  9. With the vehicle in NEUTRAL, engine running and the transmission at normal operating temperature 66-77°C (150-170°F), check and adjust the transmission fluid level, and check for any leaks. If fluid is needed, add fluid in increments of 0.24L (0.5 pint) until the correct level is achieved (fluid should be in the hot range cross-hatched area of the fluid level indicator).
