Re: 3ott issues?

Is it only whilst the engine is running? Can you run through the gears OK with the engine off?

I had this problem with a car of mine a while ago. Would shift fine when not running, but on the go and I had to use both hands to get in in gear. Problem was a loose bracket.

Not sure how a C10 3OTT is set-up but my old car had a bracket that the linkages attached to, which was bolted to the bellhousing or the frame (can't remember). All it did was keep the linkages aligned properly. The bolt kept coming loose, causing too much slop in the linkage rods. Tightened it up with some loc-tite, and never had the problem again.

Trying to looking my factory assembly manual for a layout to see if it has something similar, but you'll probably have the problem fixed by the time I find anything in that book. What a jumbled mess.

The truck to seems to have issues whether it is running or not. It sure sounds like there is an issue with alignment on my particular truck. Who knows what else that may come up when I start fixing the alignment on the column.

Re: 3ott issues?

As mentioned above the first thing is to make sure you have the rubber bushings on the transmission linkage arms top and bottom and they're not wallowed out or loose (bottom pic from bobschevytrucks.com). Make the column arm adjustments then the link arm adjustment with the tranny in neutral position. Also, make sure the arms are not criss crossed or binding when you shift. Have someone shift while you watch the links. If they're rubbing you can rotate them slightly to get clearance.

These bushings are at the top of the column under the steering wheel, correct?

No, they go on the shift arms in the engine compartment. On a manual three speed you two on the top and there's also two on the transmission shift arms. Years ago I had to make some from metal and rubber tubing I got from hardware store. You can also check in the "vendors" site and call to see if any of them carry them.

Sorry don't have a pic of the shift levers with them installed.

Here's a newer kind on this thread. http://67-72chevytrucks.com/vboard/s...d.php?t=483060

Forgot to add this thread that shows the levers with grommets installed: http://67-72chevytrucks.com/vboard/s...d.php?t=256851

I got it now, took a look at those few threads and a closer look at the truck tonight. Should have it going again by the weekend!
