Did you find a "cure"? I have a 2001 Lincoln LS V8 with 330,000 miles on it. It has been one hell of a car, but after about 315,000 miles the reverse stopped working.

I have an 02 with the 3.9ltr eng over 100,000 mile the reverse went out on it. There was no slipping or intermittent only indication was a couple times when you tried to shift into reverse that you had to use extreme force to get the shifter to move into the reverse position. I took it to 4 trans shops without telling what any of the other shops said and telling them the symptoms. All 4 come to the same diagnosis after using their scan tool, that is the reverse band in the trans had broke. All suggested a complete rebuild although they would do just the repair for couple hundred less. Reason for rebuild is the reverse band is the first band to go in and the last to come out during the fix. The rebuild from all 4 was about $1500 for everything with 6 mo warranty. this was about 2 yrs ago still have not had it fixed wife is still driving without reverse just parks where she doesn't have to back up. All forward gears and shifting works fine except no reverse. Sorry for long post.

Unfortunately, this cut and paste from the service manual is badly formatted. However, it does list several less drastic possibilities for the cause of having no reverse. (It does list band failure as one possibility.)
