I had ford change the filte and relace the atf fluid . It a seal trans , so they are the only ones that can do it . Do u think it could be a val cover problem are a computer problem ? This same problem has happen with other onwer's, They have had this same problem with ford 's downshifting problem too . A lot of them have had a patch install to correct the problem, for some it work and for others it didn't work. Any other ideals ?
