these old auto tranies sometimes have adjustable clutch packs. check your service manuals for proper adjustment. It may just need rebuilt. R&R it your self to save $$$! See if a local auto school will rebuild it for you. The cost is a small fee + parts! the bad part is your down 4 to 6 weeks but like most people we have more time than $$$! Gotta love those big fords though. I've got a 69!
