I am not quite sure I understand this. What do I need to do to change the fluid in the torque converter? I think I need to pull an inspection cover and it's drain plug. what about filling it? I can't seem to find what I am looking for, and I have a Haynes manual as well as the Factory FSM

 

Drop the pan, dump the fluid, clean the pan. Drain the converter with the plug. Reinstall the pan and plug. Add 6 quarts through the dipstick tube then start the engine. With it running, add a quart at a time till the dipstick registers full. With your foot on the brake, run it through all the gear selections for a few minutes. In Park, add till it's full. Drive it for a few minutes and recheck.

Note: If you change the filter, make sure you get the old o-ring out. However, filter change really isn't necessary,

 

Tip: When you remove plug from torque converter, go have a long lunch/dinner beak, it takes forever to drain. glc has given you great instructions (above), follow them closely. Re-check level again after driving 25+ miles too. I prefer to pour old fluid into gallon bottles so I can put back same amount of what came out. Be SURE to use the correct fluid too, else you will destroy your tranny.

 

Okay, looks pretty straight forward. I will be using Mercon V. Actually I will be using Amsoil ATF as pictured. I will be changing the filter as well

this should end up being about 14 quarts right?

AMSOIL Signature Series Multi-Vehicle Synthetic ATF is recommended for transmissions, hydraulics, power steering systems and other applications that require any of the following specifications:

Ford MERCON*, MERCON* V, ESP-M2C166-H, FNR5, M2C924-A;

 

I always check my owners manual to be 100% sure on fluids. 14 qts. sounds right. Owners manual will also tell you how much fluid. I always added 1/4-1/2 qt. of Lucus tranny treatment when doing changes...the thick gooey stuff. Some don't recommend it but I have always had good luck with it. You did not state year of car/truck....not needed as long as you are sure what you are putting in....change the filter too. I added a tranny plate cooler (BCM 70264) to all my cars/trucks. I install the cooler after the radiator lines. I live in hot Florida and it extends life of fluid and life of tranny by 2-3 times imho.....well worth the extra $100 or so if you plan to keep your car/truck a long time.

 

Truck is an 01 with a 5.4L (L code) engine. Xlt, tow package, all of that, 4x4, 4.56 gears with limited slip, supercab
does have 174k miles on it.

 

Do NOT put any additives in it. They are for sick transmissions to prolong a rebuild.

That Amsoil is the correct fluid. Reuse the pan gasket unless it's damaged.

 

There wont be any additives.
