I have a 95 ford taurus gl 3.0l with AX4N METRIC Transmission. Its my first attempt to rebuild. Ive bought the Ford AX4N REFERENCE MANUALS volume A&B. Read everything I can find for two months now. Anyways, everything has gone smooth til the piston in the forward clutch assembly had blown out seal. No problem ordered new one part # F4DZ-7A262-AB . Well the seal on this bonded piston is slightly different than the one that came out of it. The one that came out of it is clearly stamped in the rubber seal #F4DP-7L140-AA. BUT, Try to look it up it can't be found until 97 in another transmission an looks nothing like my piston. The one I ordered from the manual looks like it except the bonded seal. And it will not pass the air test before installation. Anyone any advise would be appreciated
