Late model Chevrolet 6-speed automatic transmissions are notorious for loosing the shifting linkage. I've dealt with the issue on White Horse before. Now it came back around.
Not a fun situation to run into. If the shifter on your column goes haywire when you try to put it in park or reverse, she probably came undone underneath. It's been about three years since I've had this happen on White Horse. But last week, she came undone. When I crawled underneath it today to address the issue, this is what I found, almost off.
This is what you usually find when if comes undone, just no communication to the transmission. Be darn sure you have your wits together before you crawl under a vehicle in this situation. Make sure the engine is off and the park brake is set!
The first time it happened I almost bought a whole new cable. However, beings it's happened enough, NAPA just started selling the grommet that holds it in place.
I should have known something was up when they came in a pack of three.
I've found that a little WD-40 helps it pop into place.
The little loop I think is only there to help with instillation. Once in place, I cut it off.
Here's the key I've found to help keep it together. Really press the grommet into the recessed part of the linkage pin.
Giddy up.
On the road again. Anytime you crawl under a vehicle to address a shifting situation, be careful! There are many variables that can be at play. That being said, you can handle this issue. If your shifter isn't shifting, it's probably the linkage. If crawl under to take a looksee or tackle the problem, use your head. Make sure precautions are in place, such as the engine off, setting on level ground, and the park brake is set. We ranch today with an eye on tomorrow.
Funny you have this on transmissions. I just had my annual fit about automatic transmissions.
ReplyDeleteI've owned three new trucks since leaving university 36 years ago. All three have been standard transmission trucks. My last one is a 2006 Dodge 3500. I now really can't replace that as it would require me to own a truck with that horrible abomination called an automatic transmission.
I've had two automatic transmission trucks in my life as well, both 1974 models. I'm not going back, although my 1/2 Dodge was a pretty good truck.
I've even looked into how hard it would be to drop a manual into a newer truck. Suffice it to say, if they're newer than 2019, when society collapsed by there no longer being a manual option, it's pretty tough. Computerization is actually the reason why. The computer on the engine would look for the automatic transmission, but find the manual, and come back crying.
I realize none of this relates to what you posted.
I had a car once, a 1954 Chevrolet sedan, in which the linkage popped out all the time. Apparently it was common to that model. Fortunately, it was easy to pop back in, and you could do it from above with the hood open.
