So the reverse band is worn out on the transmission. I have a couple of options. There is transmission from a rusted out 2003 ls for with 127,000 miles for 100 bucks and there is one from a salvage yard for 300 with 145,000. Is it worth one or the other or should I get rid of it.Or just rebuild the one in there. Also can the mustang pieces swap out the Lincoln transmission parts. I hear they are better.
