4R70W Modification
Has anyone performed the "J- mod" on their Expedition transmission? Here is info I discovered on it:
The most popular modification for the 4R70W is the "J-mod". It is a shift kit specified by one of the ford engineers that designed the transmission. It offers quicker shifting, smoother operation, and increase service life. All parts can be bought at Ford dealers for less than $60.

Honestly-the best thing you can do is ditch the truck VB,and get ahold of an '01-'03 car VB,and j-mod it.
