I don't think it's the seals, but a friend who was once an engineer on
the P71 Crown Vic (police) program at Ford once told me that auto trans
life is very simple: drain and fill the transmission pan every 50K.
Don't worry about the torque converter or the filter, just drain and
fill, then do it again the next 50K. You can drop the pan and do the
filter every so often, but don't obsess about how much you get out or
how you do it, just get new fluid in there regularly.
That's kinda been my model since.
John.
