This brings back horrible memories of when i money shifted my dc2 type r. Engine exploded F1 style (shattered pistons came out the exhaust) i spun out and the car almost caught on fire. I was scared of shifting fast for a good couple years after that ( still am a bit honestly).

Even that Drivetribe article is wrong. It's just the natural resistance. If the manufacturers really wanted to prevent money shifts, it would be EASILY doable now that these cars all have Hall Effect sensors to determine shifter position for rev matching. I suspect there is some failure mode / liability issue that stops them from doing it. It's pretty hard to money shift a BMW with rod shift linkage like you said, but I could see it happening with a cable shifted car. I've noticed they tend to be smoother and give less resistance. My Mazda 3 will let you into anything but first pretty easily at any time. Z4M... not so much. |

Maybe I'm confused about the lock-out's, I thought I had definitely read that about my STi.
But in any case, a shift from 2nd/3rd to 1st should not be possible at certain speeds/rpm's, and should be easy to accomplish. 4th/6th to 3rd might be a bit more difficult. |

I dunno, maybe i just have too much mechanical sympathy but i've always felt perfectly timed (read: not as fast as possible) shifts felt way more satisfying than balls to the wall "how fast can i go" shifts. One of my 24 hours of Lemons teammates always shifts our race car like a crazy person. He looks like a human-DSG out there. That's fine, it's a race car so there's no real excuse not to beat on it, but at the same time, we run the exact same times on the track and i'm double clutching my downshifts AND giving a second for the revs to drop between gears on the upshift. It just doesn't save THAT much time at the end of the day. |

Interesting. My '18 STi definitely did not have a lockout. It was no problem at all downshifting into 1st. But 8+ years in a '09 WRX that was nearly impossible to get into 1st while moving at any speed trained me to not even bother in any manual car I drive. |

SkyDubBlue, were you driving in DSC OFF mode at the fatal moment ?
In the M2 and M2C, except for DSC OFF mode, rev-match 'warns' on downshift about over-rev before clutch release. The unpleasant over-rev noise allows you just the moment of realization to refrain from releasing the clutch - you correct the gear shift without damage. However, in DSC OFF mode you shift into a gearbox death trap: no warning 'over-rev noise' before releasing the clutch. You release the clutch and you hear 'The Expensive Sound'. Many people wonder why rev-match is hard-coded in all modes on the M2 and M2C (no auto blip on/off toggle as on the Cayman GT4), except for DSC OFF mode. IMHO 'money shift' protection is one of the main reasons.

What can i say? i was pushing the car hard and type r Honda gearboxes are known to be easy to money shift. Moral of the story, don't try to shift like a race driver in your street car it's not worth it, although i must say, the insane trail of smoke i left behind was a sight to behold .
In the end honda quoted me about 9000$ for a new engine,clutch, flywheel...etc , i refused and the car still sits at home to this day (it's been about 10 years now). |

Basically it's a highly aggressive down-shift on a MT. Which means you end up wayy over red-line the engine. It's called money shifting because doing that will tend to harm/destroy the engine, and that is money out of your pocket because warranty doesn't cover it.

Your point does hold true though if you attempt to shift at a point that is below redline. |

Agreed. Luckily I never actually overreved the motor, but did get close one time when I was sloppy with the shifter. An audible warning would be awesome for those boneheaded times.
