Late model, Chevrolet 6-speed transmissions are notorious for loosing their shifting linkage. This is about the third time I have dealt with this issue on White Horse.
If you are going to put your truck in park or shift to back up and the shifter on the column just runs freely up and down, your shifting cable probably came off the transmission shifting arm. This happened to me last week, which was probably the first time in three years or so. When I crawled under it today, this is what it looked like, about to come off.
The shifting cable has to pivot as its selects gears. The method they use to make all this action happen is a hard rubber grommet.
The first time it happened, I almost had to buy a whole new cable. However, it must happen enough that NAPA just started selling the grommet only.
I should have known something was up when they came in a pack of three.
I've found that a little WD-40 helps the new grommet pop into place.
I think the loop on the outside is there to help pull it into place. Once in, I cut it off.
The real key I have found is to really press the grommet into the recessed part of the arm stud. Seems to set better and last longer.
Giddy up.
On the road again. This is really not a fun situation to have happen. Crawling under a truck to reattach shifting linkage can be a dangerous proposition. If it happens to you, make sure and shut the engine off and set the park brake before shifting any gears from underneath to line the arm up to the cable. Just use your head and you'll be fine. If your shifter isn't shifting, don't panic. It's probably your linkage. If you crawl under to take a looksee or tackle the job, be careful.
Ranch today with an eye on tomorrow.
