Question about 1986 Ford Thunderbird
Based on your description, I'd guess you have the AOD transmission. That was a not so common option on our Fox Birds. There is a cable that goes from the throttle linkage down to the transmission to modify the shift points. If that cable comes loose (which really is a common problem), then the shifting issue you're describing will occur. The linkage was connected by a plastic bushing pretty close to the same place the throttle cable connects. That bushing dry-rots, crumbles, falls out, and then the linkage comes loose. Ford sells a modification kit with a bronze bushing to replace the plastic one. I had to make the same repair on my son's 1990 'Bird. I have the older C5 3-speed auto in my '86, so don't have the cable linkage. If I remember correctly, the repair kit was only about $11, however, is ONLY available at Ford dealerships.

Maybe the stick in the transmission is broken.
