Automatic Transmission Linkage
« on: November 18, 2023, 15:58:09 »
The Shifter suddenly became very sloppy. I ordered and replaced all the bushings. This of course, removed the excess play.

The issue is that I cannot adjust the linkage rod perfectly. In most cars there is a barrel type adjuster to finely align components.  The closest I can get is one entire turn of a thread.

I also suspect the rod was installed backwards at one time by a mechanic.

There is also no access panel present on the center tunnel.

I own the autopress repair manual and am perplexed.

Any help or suggestions are appreciated.

Regards,

Brion

you can get access via the gearstick, you need to remove the chrome surround (four screws I seem to recall) which comes away and you can see the linkage, that might help.

Let me add some photos of the linkage. As stated before, it appears it was installed incorrectly. The issue I am having is wherethe adjustment of the rod occurs. The clevas can adjust; but never is able to connect in the correct position and orientation. There is also play where internally threaded barrel attaches to the rod. Is this normal?

There's a small rubber bushing inside of the barrel. Once that thing falls apart you will have all kinds of play in the linkage. That small part is replaceable PN  113 267 01 83

Thank you.

My co-worker and I discussed the possibility of there being a rubber bushing within.

Wow!

How do you access the nut on the linkage bar? I worked on the car on Sunday. The linkage was reversed. Once it was turned around I was able to dial in the shifters position. I just do not see how to tighten that nut.

Better to adjust by loosening the two screws that hold the lever to the transmission and moving the lever (it pivots).  When you think you have the correct adjustment, tighten the bottom screw and see if the linkage moves correctly through the gate.  When you have it right, tighten the upper screw.  Two 10 mm wrenches needed.

I know this is an old topic, but is there a bushing on the left-most eye of the arm that connects to the transmission? And, where can a guy order one?

Perhaps the equivalent of #28 on the diagram further up the thread.  Only i need the bushing for the end opposite of the one where it shows #28.

Yes, there is a bushing in the ring at the end of the arm where the latter connects to the lever at the side of the transmission box.  The bushing is made of nylon. It is actually a ring that must be pushed  over the pin on the lever.
