What is the absolute best way to set/adjust the shift linkage on a 67 four speed. Currently it wants to hang up going from reverse into first gear.

Re: C2 shift linkage
My 68 always shifts better after I remove the shifter assembly, take it apart and clean and relube it. Old grease is really sticky. -
Re: C2 shift linkage
MY '63 may be different from a '67 but, per the Shop Manual, I needed to first make this block (the manual describes the dimensions of the block) piece. Then, again per the manual, I made the appropraite adjustments. I could go through the procedure for you here but, it would be better if you had the Shop Manual.
When I was done, the shifter worked very well. Note: The adjustment may not fix your problem but, it needs to be checked to confirm that it isn't your problem.
Good luck,

Re: C2 shift linkage
Make sure that your shift rods are on the lower holes of the gearshift levers
on the transmission itself. The upper holes are utilized for a short throw sequence,but may result in difficult shifting. Also consider 75 weight gear oil
(such as Redline) which Duke recommended in earlier posts. Doing both of these
immediately corrected my shifting problems in my 65 roadster.Comment

George:
The other advice listed here is good. The first thing I would look at would be for slop in your linkage. Make sure all the bushings are in good shape and the holes in the shift arms aren't egg shaped. Also, if this is not too challenging, check the cage around your shift arms. If you have excessive side play or if your linkage is worn, all the adjusting in the world will not make it shift reliably.Comment

Re: C2 shift linkage
Mike,
I remember from "way back" that you can't live with any slop. Reverse rod was excessive and I'm rebushing it and using the proper coiled clip. When you said check the cage, what am I checking for? Also how do you check the line up of the slots with the linkage way up in the tunnel?Comment

Re: C2 shift linkage
George:
What I meant about checking the cage: make sure the shift levers do not have excessive lateral slop in the shift arms actuated by the handle.
As for adjusting the linkage, I didn't fool with a guage like the manual says. I would pull up on the "T" handle and pull the shifter through the gate, right to left to right, alternately putting very slight pressure fore and aft. This way you can "feel" the adjustment in the handle. Then crawl under the car and make the appropriate adjustment to the rod clevises.
For a sloppy shifter/linkage, I found it beneficial to have the reverse arm gate in the shifter slightly out of adjustment to the point that the shifter has to be pulled back toward second gear to get it out of reverse. This eliminates the thing getting hung in 1st and reverse until you get around to rebuilding/refurbishing your linkage and shifter.

Re: C2 shift linkage
George,
-------You start out at a disadvantage with a 67 as the shifter is factory-mounted to the frame,not the trans itself.Check the trans-bracket to frame mount bolts.They are often loose and when they areall kinds of problems arise.Also,adjustment of factory shifters(once re-bushed and tight)can be done much like a Hurst shifter.Instead of using the round alignment dowl you use a flat spade,as mentioned above.You almost have to have the shufter out on the bench to see where and how to accomplish this the first time.After that,however,you will be the king of shifter adjustments.Hope this helps.............Bill SComment
