Transmission Fluid Drain and Refill: Refill

  1. Use only clean automatic transmission fluid.
  2. Once the fluid exchange has been completed, disconnect the flush and fill machine. Reconnect any disconnected fluid cooler tubes.
  3. With the 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 0.24-liter (0.5-pint) until the correct level is achieved (fluid should be in the crosshatched area of the fluid level indicator).


  1. Position the magnet into the transmission fluid pan.

  4. CAUTION: The use of any other transmission fluid can result in the transmission failing to operate in a normal manner or transmission failure.
  5. Fill the transmission.
    • Add 4.7 liters (5 qts) of clean automatic transmission fluid to the transmission through the fluid filler tube.
  6. Start the engine. Move the transmission range selector lever through all the gear ranges, checking for engagements.
  7. With the 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 0.24-liter (0.5-pint) until the correct level is achieved (fluid should be in the crosshatched area of the fluid level indicator).
