If only it were that easy...
I've read everything I can find on this site and several others related to the transmission problems associated with the 4.6/4.8is and have yet to find the answer to my problem.

You'll need to post your specific symptoms and any other info for us to try and help.
More than likely you are experiencing a harsh downshift when coming to a stop, have a low speed shudder, clunks or hesitates to go into reverse, or are have a slip between gears (like the rest of us). These are all common issues and well noted here on the forum.
