The A4LD transmission used in your truck is the same one they used behind 2.3L 4 banger mustangs. The larger mustang Transmission AODE/4R70W only fits behind 5.0L V8 (302). It will not bolt up to your 4.0L. So whoever is giving you information is interpreting it wrong.
By the way, I had the same problem with my my Fullsize Mustang transmission. (AOD) Was driving down the road in Overdive, and all of sudden I saw fluid and smoke spewing behind my truck........everybody behind me was covered in ATF. When I got out, my whole truck was dripping w/ ATF. I put a couple quarts of spare ATF in there and drove to the nearest town (after I cooled it down) When I got to the repair shop I had five quarts left in the whole tranny max!
This all happened when I had my explorer loaded up, as I was relocating to a different state.
