I have a 1974 that is experiencing shifting problems. The shifter will not easily slide into first. It will go into all other gears easily, but seems "blocked" from slotting into first. There is no gear grinding. If I shift into reverse first and then pull down it will go into 1st normally most the time. However, if I am trying to downshift from 2nd or above, the 1st gear position is blocked and the shift goes to 3rd gear. I am trying to understand if the problem is with the linkage, simple transmission mx like changing the gear oil or is it time for a rebuild. Thanks in advance for your insights.

Rebushing the entire linkage and using brand new set screws is step #2. I have a couple of shifter assems that makes me wonder how they ever got in to 1/R. Filthy springs with little give. Plates where the hardened edge is dished big in the middle. Levers with wear gouges at the plate contact point. Cheaper than a transmission.

I will take review the linkage and post my findings. I tried to add a few photos but exceeded size. Will reduce and add a few pics to the post. I rebuild the pedal assembly a few months ago and the clutch improved significantly. So I am hopeful for a linkage refurbishment. |

A shift linkage bushing kit and 6 hours of effort got me all shifts crisp and back to normal. At first I did not think the linkage was too sloppy. I realized after that the set screws were not fully seated and the new bushings did tighten up the linkage. Virtually no play from hand to trans. Thanks so much for the spot on info.
