Mine had a plug in the converter, I just had a friend manually spin the motor until the plug was pointing straight down. I take it the newer models just don't have this plug then?

You are going to need a 10mm socket, lots of newspapers and a large drain pan. I personally went to home depot to get a concrete mixing tub, it was cheap and it’s big enough to get the dribbles from all around the pan.

  • Pull the black cover from under the torque converter (front bellhousing) and spin the engine around till you see the drain plug.
  • Undo the drain plug, and let the torque converter drain out while you are undoing the pan bolts.
  • The OEM pan gasket is re-useable, and at 160K I was still on the OEM transmission filter (it was still very clean). Remove all bolts from pan, and drain oil from pan into container. You can replace the filter if needed.
  • Take a clean cloth or rag and clean the magnet.
  • If you see a rubber plug in the bottom of the pan, don't freak its there from the factory as a seal in the dipstick. Replace the pan and its bolts, DO NOT OVERTIGHTEN, the case is aluminum and will strip.
  • Replace the drain plug till it seats tightly.
  • Pour 5 qts. down the dipstick, start the truck let idle for 30 seconds to pump the fluid into the converter. If you don't do this and pour all the fluid in, it will come out the vent of the transmission.
  • Repeat the 5 qts. and idle again, this time placing into drive and reverse to fill the valve body.
  • Place back into park, and check the fluid level.
  • Add till full (usually about 2 more qts, but I’ve had some that took only 10 to refill)

Are you refering to the drain plug on the torque converter or the drain plug on the transmission.

How dirty was your trans fluid before you replaced it? Did it appear dirty?

Again. Is this the torque converter plug or the trans plug? I think I might be missing something.

Thanks for the advise. I will be doing this soon on a 98 F150 5.4L with 107k.

Default Transmission Maintenance

I am the 2nd owner of 2002 F150 supercrew. I have 90K mile (50someK mine) Is it too late to have the transmission flushed? I assume this will be the first time. Should I change the filter also?

I was concerned about hearing about dirt getting caught in valves or other issues, especially since I pull a camper several times a year. My Ford goes in Friday for rear axle seal leaking, mechanic at work thought it would be a good idea for the transmission maintenance also.
