1967 C10 Won't shift gears unless truck is moving

[sgraham1]

Good afternoon all!

First time poster here!

I've got a 1967 Chevy C10. First issue is that the truck won't shift gears unless it is rolling. That's not normal right!?

Second issues is that when in neutral or shifting gears, the shifter feels somewhat difficult to move. It's not a smooth shift and feels just kind of...off. Like there's some resistance or something.

The linkages look ok so my next steps will be to try and make the shifter adjustment per another post on this site (putting a 3/16" drill bit between the gear selectors) and to replace the bushings. Are there any other issues I should be looking at?

Thanks all!

lubricate the moving parts especially the shifter oon the column

Check your clutch adjustment. If it won't go into or out of gear unless the truck is moving, it's likely the clutch isn't completely disengaging.

I agree with Cliff....

Problem is the shift tube inside the column, it gets dry and/or the old grease gets stiff. Put the shift lever in neutral and spray some PB Blaster, Liquid Wrench, or something similar (not WD-40) into the steering column, where the shift lever goes in. Don't be afraid to give it a good dousing. After you spray it pull the shift lever up toward you and push it back down toward the dash. The knob should move up and down a couple of inches. Do this 4 or 5 times. This will help free up any sticking in the shift lever tube. The reason the shift lever moves up and down is to engage the two different gates, one for first and reverse and one for second and third.

Also spray the linkage and levers at the bottom of the column and trans linkage under the hood.

truckster makes a good point too.
