      The issue is that the engine and transmission are locked at one speed at that point. All the electronics in the world won't help a drivetrain that can't handle it. The only thing would be a little mechanical lockout, but once it has already occurred, then it's too late.

      They should just make the entire gauge cluster be like a skull and crossbones or something when you select the wrong gear (lol). But even then usually you're shifting fast enough and looking on the road, it probably wouldn't help much.

      There would still have to be some mechanical component (i.e. shift locker-outtie thingy or clutch engage override). There's no way to protect from mechanical overrevs by cutting ignition or fuel or whatever. If he had let the clutch out in that gear + speed while the car was off the outcome would have been the same.

      The car is going to go into gear no matter what if it's a manual transmission. You can cut fuel, you can do whatever you want, but the motor is still going to spin at the same RPM as transmission. It's that simple.

      Just like how the motor keeps spinning, puffing air, and nothing changes when you turn the car off with the clutch engaged while under power.

      For instance, in my 325i.

      If I'm going 50MPH in third gear and I turn off the ignition (just one click, still need to steer), the car cuts fuel, engine still spins, besides friction slowing you down, literally nothing changes, it just feels like you let off the gas. Turn the key back to "ON" position, and the engine starts getting fuel. No starter, etc.

      So with that being said, you could in theory run a car up to the top of third gear on a dyno with the engine off, downshift to second, and blow up the motor. Without the motor running.

      That is why something like rev protection can't save you in a money shift.

      yea exactly and same reason you can jump start a manual car by getting it rolling and dropping it into gear

      Well it could be done by using a couple of systems but good luck engineering this ****:
      1. Non-rotating clutch disk mounted between the block and flywheel. The overrev disk would engage if the ECU senses an incorrect gear selection or a sudden rise in RPM that would indicate a money shift situation. The tough part would be to fine tune the engagement to slow the motor before it overrevs and not lock the motor and shock the rotating mass
      2. Electronically actuated clutch on the output shaft of the trans that immediately disengages if the incorrect gear is selected or a sudden RPM rise like described in the first situation

      Maybe we could get a well-known van based CNC shop to work these plans up.

      There's a really easy fix for this.

      So...turns out this is a crank hub failure AND a money shift.

      Probably an easier implementation would be something that looks like a gated shifter underneath the booth, with solenoids locking out certain gears at certain speeds with a basic microcontroller doing the actuation.

      But why!? It's still your fault. The manufacturer isn't going to cover a damn thing if it's under warranty so why add something that 99.99% of the time isn't needed, and the .01% you don't have to pay for anyway?

      This will never be solved in engineering. Manuals are going away and in the meantime BMW (or anyone) would love to point and laugh while you hand over another 30k.

      Easiest implementation is crappy synchros that won't let the car get into gear. Money shift is nearly impossible on my Alfa

      Some people in this thread are forgetting that seat belts and airbags had to be federally mandated. Car companies are businesses. They won't spend money to prevent you from spending more money after doing something stupid.
