Shift / linkage problem

I have an 88 tbird Sport with AOD and a floor shifter. Apparently my shift  stopped functioning correctly so I had to remove it which looks stupid now. I can shift with my thumb by manually pressing down on the white button that engages the shifter, but the  itself will no longer do this. Is the linkage worn out or could it be the  itself? How can this be fixed ?

This is what I'm dealing with:

Thank you for any info or help! :bowdown:

I have an AOD shifter from my 91 Mustang LX that I won't be needing.  If I can dig it out and you decide you want to replace it, let me know.

Not sure if that will fit correctly...or will it ?

It should.

Usually the white nylon rod inside breaks...first I've really heard of the button or spring inside going bad.

You should be able to pull the white part out and check if it broke. It looks like a string of beads. I fixed one with a plastic ball added one time, like from fake bead jewelry.

Okay I was afraid to pull that rod out but I think that is the problem..the  and button / spring seem to be fine. How far out did you pull it ?

All the way out.

I can still shift the car manually by pressing the white rod down with my thumb, which is what I'm currently doing. WHy wouldn't the  and button do this though ? Is the white rod not sticking up far enough ?

When the string of beads breaks it lets it compress in the broken area so the shifter button doesn't press it down far enough.  I was lucky enough to find another shifter in the junkyard and pull the intact piece from it but you should be able to come up with a creative fix for it.  I think I've heard of people using ball bearings for the area under the break and retaining the upper part of the string.

Here is mine from when it broke.

I replaced my broken "string of beads" by cutting off a piece of an old toy hand held windmill on a plastic stick that my daughter wasn't using any more.  You can probably buy one at Walmart or dollar store.  Just cut the right length, lube it up and slide it in.  The plastic handle on those windmills are tough and very flexible.  Good for going through the s-shaped shifter tube.  3 years later still working mint!

Were you able to get the old broken piece out ? If so how did you do it ? Also how did you know the correct length of the piece so the shift  fits correctly ?

I used a small piece of 2-sided tape on the upper broken piece and fished it back down with needle nose pliers and grabbed it that way.  Took some time but eventually got it.  If I had to do it again I might have tried one of the "flexible claw pick up tools" which would have worked even better I think and they are usually less than $10.  For length I just laid out all the broken pieces together to figure out the right length.  After I had the right length I rounded the edges and greased them up so they wouldn't damage the contact points especially the shifter  button.
