Transmission Fluid Drain & Refill: Draining

WARNING: This page is about a different car, the 2004 Ford Pickup, 2004 Ford F550 Super Duty, 2004 Ford F450 Super Duty, 2004 Ford Excursion, and 2004 Ford Cab & Chassis. 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, and 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 vehicle types:

Use the method that is applicable to your vehicle.

All vehicles using a suitable flush and fill machine 

  1. With the vehicle in NEUTRAL position it on a hoist. Refer to Jacking & Lifting .
  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.


Vehicles equipped with a fluid pan and torque converter drain plug 

  1. With the vehicle in NEUTRAL position it on a hoist. Refer to Jacking & Lifting .
  2. Remove the drain plug and allow the fluid to drain.
