see this thread: Changing ATF Fluid in a E4OD and 4R100 transmission .: Articles

and never use Lucas oil in Anything - if you like your truck. Do not use Mercon V either. And someone will chime in with what oil is thought highly of around here. I think it is the Mobil 1 syn. Good luck.

Use MERCON V. Ford has discontinued MERCON and changed MERCON V to be compatible with the 4R100. The article could use some updating.

The other tip is to warm up the trans before starting the flush. It works better on a warm trans.
