Lots out there about floppy shifters and the like, not a lot about linkage to the shifter. Instead of creating a new thread figure better to revive this one and include some details.
See photos for some details that can help in the floppy shifter discussions or other edumacation for the curious at heart.
In the end my problem was that the transmission linkage cable had come off of the shifter. After removing the assembly from inside the console, found the plastic bushing remnants in the bottom. (It wasn't necessary to remove it, I was just curious how far I'd go and what all I could find).
Toyota does not and would not sell the retainer bushing-- it's part of the entire cable assembly for $280! Automotive stores have some general ones and the guy told me to come on in and we'd see what may or may not fit... but almost all of them were for American vehicles. I had no problem doing that, but it was a couple days til I could go. Zip-tied together in the meantime...
THEN :lightbulb: even simpler idea. I swung into ACE and sampled both tooth lock washers and push-washers.
In the end I used a 3/8 starlock/push washer, and if that comes free, I'd switch to a spring washer next time.
My symptoms: Car was in 3rd for some reason (an automatic) and indicated so on the dash. Put it in neutral, still in 3rd... put it in reverse, still in 3rd... put it in park....still able to move in the parking lot.
Here's the dumb part... I decided to turn it off to see if it would reset!

If you don't catch it, I did as SOON as I turned it off.... The vehicle won't start unless it's in P or N!!!!!!!! DAMN!
I've had alittle tranny hiccup for a while, and really thought, Oh fudge, this is it... Panic call to my motorhead buddy and we went straight to agreement.
My son and I sitting in the parking lot tried all kinds of fuse items and unplugging harnesses to see if we could get the vehicle to "not see" the transmission and be willing to turn on so I could drive the 2 miles home in 3rd.... no luck (duh).
After an hour and a half, including rocking the car to see if I could get some solenoids to let go, getting my wife to bring my tools and giving some swift bangs along the tranny case (I'm sure it laughed well at the idiotic attempt), I decided to get it towed and let it cool down and maybe just cooling would allow a stuck solenoid to release.... IF indeed that was the problem (the better of problems than the transmission).
While waiting for the tow truck I thought, uh, let me see if I can figure anything out in the shifter.... Having never been inside one before. After wrestling with the console for 20 minutes figuring out where the releases were, pulled it off and within seconds noticed the arm end of the cable just flopped down. How ecstatic I was!!!! (I hoped).....
Sure enough, that was the issue.
Hooked it back on, drove home, and for a day kept reattaching it til I considered zip-tying it.... and now 68 cents later, it's all done!
I hope this helps somebody in some fashion, whether this problem or any other where the pictures answer some questions!
(not quite sure how to embed images between text.... or I'd explain them better)
