I believe that the '00 had revised syncros or some such in the tranny.
Part way into 2000 production (early January 2000 IIRC) the trans was revised. The main change was roller bearing 1-2 shift fork, the best answer to cold shift problems. I don't know what all other changes were made, but the fluid capacity dropped from 2.7 quarts to 2.2 quarts and Ford started installing "Honey" manual trans fluid.
