Good Rafa, the transmission of the Wisdstar with V6 engine 3.8 lts 01-03 is perfect as it is the same transmission. Just because windstar has the code AF50N and Freestar 04 with V6 engine 3.9 lts and 4.2 lts uses the code AX4N. Windstar 95-00 with 3.0 l and 3.8 l V6 engine uses the AX4S transmission and is slightly different. I hope the information and luck serve you.
