AODE problems

[daddyo]

Let's see if there is intellgent life out there because Ford seems to have no answers. 1994 auto v-6 with 52K. The problem is my transmission will SOMETIMES shift hard or hang up(free rev) at around 35-45 mph. This happens with O/D on or off. They (Ford)
have replaced the IAC, MAS. After which they determined it was an internal trans problem. I went for a second opinion. Took it to a a good trans shop who cracked open the pan to do a visual and all they found was a dirty filter and fluid. After all this I still have the problem. So I crawled under to see if there was anything obvious that some how has missed. Well i did find a cooked wire harness to the VSS. So I spliced in a harness end off a 94 t-bird and changed the VSS. I am to the point of still not wanting to believe the people at Ford about needing a new trans. No other problems the car runs great other than this. Any ideas out there.
