Hope someone familiar with this can help. We have an annoying rattle in the shifter, especially in 3rd/4th.

Last summer we had our mechanic install the GW shift repair kits, front and rear. Shifting improved, but afterwards started noticing the rattle. Rattle might have been there all along, not sure.

I had the spare tire off so did some looking around. Is there anything missing in these pictures?

I seem to recall a thread where someone used UHMW to fashion some NLA tabs. Is that what we need, and potentially the source of the rattle?
We can make the rattle go away by placing very light hand pressure on the shifter knob.

If so, where would they go, how do they function?

Thanks!

Mine does the same thing. I can get it to go away by adjusting the shift plate from the top (loosen the two bolts, move it around a bit.)

You can try cutting short pieces of rubber tubing to go over the ends of the tabs. That will make your shifter feel tighter but will probably not have an effect on the rattle you're describing. You can always pull them off if it doesn't work for you, easy to experiment with.

I found the thread I was thinking of.

Tabs on ears of our shift rod to appear to be AWOL. Off to Rockler to get a piece of UHMW. Appreciate any helpful hints.

Send some pics when you get rolling on it. Sorting out my shifting problems and adding some new bushings to the shift-fork aka ears is on my top to do!

Thanks for the suggestions. Here is what I did:

Image may have been reduced in size. Click image to view fullscreen.


I decided the UHMW was going to be fussier to machine than I had tools/patience for, will be returning the $25 piece (3/4" x 4" x 24") to Rockler.

I followed the lead of supdave66, and used some tubing. Instead of FI hose, though, I used some pretty firm yet flexible hardware store stuff that I had around. Heated it to make it pliable enough to squash and fit over the shift fork tabs. Tight fit. Used JB Weld for adhesive. (While the rod looks greasy I cleaned the ears very well before the fix).

Shifting is improved and more secure, tighter. Didn't affect the little rattle in 3rd/4th, I may need to just accept it or possibly adjust the shifter base plate from above as suggested by Californio.

A side benefit is I now have a much better understanding of how the shifter gatebox works, I can visualize what is going on as I shift.

Thanks!

Be interesting to know how well that wears compared to UHMW.

My thoughts too. I would bet not as well as UHMW. But it was pretty quick to do. Time will tell if it is good fix.

Have two spare NOS shiftrod. One for 2wd & one for Syncro. Obviously no wear in the plastic pads. PM me. 1st come 1st served.

REVISING to say both shiftrods are spoken for. Have details of various solutions to this from the Australian Syncro Forum with detailed dimensions from me. PM at Syncro (at) gmail (dot) com if you need assistance rehab'ing your shiftrod.
