Exclamation Misdownshifted from 3rd to 2nd and over the redline

So I just now was going to upshift to 4th, but I misdownshifted to the 2nd at 93-98km/h. The revved just passed the redline like about 7700, 7800rpm...
That that gonna cause a huge damage for the engine and the clutch?

If I rev mine out to the limiter in 2nd I am at 98km/hr indicated. If you truly were doing 93 - 98 when you inadvertently went into second, I don't see how you over revved?

It's totaled. Time to buy another car. I suggest a new Honda Civic in auto.
If you keep driving it, the clutch is going to brake and go through floor board and cut off your manly bits.

Lucky for you I'll gladly take that death trap of a car. I'll even give you $300 for your troubles.

I was just so scared... I cant really remember exactly how fast was that, but I just remember the rev was over the redline like couple hundreds... I'm just currently so worried about the engine and clutch if they are damaged...

nah no damage. If you misshift from 5th to 2nd, now that might be a problem

Couple of hundred is not a big deal. Just don't keep doing it. Odds are if you damaged anything you would already know it. Damage caused by a serious over rev is usually (not always but most of the time) immediate and extreme. I wouldn't be worried at all.

That's called a money shift. Usually after you do that, you end up spending a lot of money to fix it. If it's driving fine, no problems and nothing happened after- you got lucky. Don't do it again

Did you try to press the clutch as soon as you heard it start to over rev?

I did not... cause it just hit like slightly above the redline and then it dropped under the redline right away. I'm just so worried about it.

How do you manage to drop it into 2nd gear, were you aggressively driving? 4th gear from 3rd should be a short downward movement, especially on this car.

Michael.
Without actually checking the ratios, I'd say this speed is reasonable for a slight over-rev with the shorter final drive of the 2017.

Different members mentioned an occasional mis-shift. I haven't heard anyone to have problems afterwards. In fact the chances after a mis-shift are to have an accident (you lose traction), than to have issues with the engine.
