Transmission Fluid Drain And Refill: Draining

WARNING: This page is about a different car, the 2002 Ford Econoline. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION: Always refer to the instructions supplied with the flush and fill machine.
NOTE: Draining fluid from the transmission by removing only the fluid pan is acceptable for vehicles that do not have a torque converter drain plug, for normal or severe duty fluid maintenance.
NOTE: A new procedure for draining and adding transmission fluid using a suitable transmission flush and fill machine has been added. The following procedure has different methods for draining and refilling the listed vehicles:

Use the method that is applicable to your vehicle.

All vehicles using a suitable flush and fill machine 

  1. Raise the vehicle on a hoist.
  2. Use a suitable flush and fill machine to change the fluid.
  3. When connecting the flush and fill machine, connect the machine to the fluid cooler tube after the fluid cooler on the cooler return line. This will help remove any foreign material trapped in the fluid coolers.

    Refill 

  4. Use only clean automatic transmission fluid.
  5. Once the fluid exchange has been completed, disconnect the flush and fill machine. Reconnect any disconnected fluid cooler tubes.
    6. NOTE: If the vehicle was equipped with a fluid filter, install a new filter (XC3Z-7B155-BA).

  6. Install a new in-line transmission fluid filter.
  7. Lower the vehicle.
  8. 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 cross-hatched area of the fluid level indicator).


Vehicles equipped with a torque converter drain plug 

  1. Raise the vehicle on a hoist.
  2. If the vehicle is equipped with an in-line transmission fluid filter, remove and discard the filter.

  14. Install a new in-line transmission fluid filter.
  15. Lower the vehicle.
    16. CAUTION: The use of any other transmission fluid can result in the transmission failing to operate in a normal manner or transmission failure.
  16. Fill the transmission.
    • Add 4.7 liters (5 qts) of clean automatic transmission fluid to the transmission through the fluid filler tube.
  17. Start the engine. Move the transmission range selector lever through all the gear ranges, checking for engagements.
  18. 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 cross-hatched area of the fluid level indicator).


Vehicles without a torque converter drain plug 

  1. Raise the vehicle on a hoist.
  2. If the vehicle is equipped with an in-line transmission fluid filter, remove and discard the filter.
