Default Misshifted from 3rd to 2nd

Alright tonight driving im doing about 85 in third gear and i go to shift into 4th. I have only had the car for about 3 weekes so im still getting use to it. I accidently shifted into second, but i hadn't let the clutch all the way out yet. As soon as i realized what i did i put the clutch all the way back in. I know my car reved high but i dont know how high. There is NO check engine light. It drives fine, but i think it is making a slight humming noise now when i get above 4 thousand rpms. I might just be being paranoid though. Do i have anything to worry about if there is no light?

Might want to get it checked out just to be safe. If you had a clutch delay, I'd think you'd be in better shape, but since you seem to have a 2000, get it checked. Even with the clutch delay, this is a pretty serious thing, so get it checked!

Get it checked. Check. Get it?

edit: Oh, make a better title for this thread. That way, when people check the thread title, they will get it.

Did you take it above redline? Was the redline blinking at anytime? If the answer to the second question is no, then it's also no for the first one and you're Ok. Since you didn't come fully off the clutch, you might be Ok but if you've got any doubts, get the engine checked. If you didn't overrev, the money spent will just be peace of mind. If you did overrev, you'll save yourself some repair dollars by getting it taken care of before any additional damage is done.

Bboy AJ, having a delay valve in the slave cylinder won't make any difference in this case. It slows the clutch engagement down enough for some slippage when the engine is running at full throttle and trying to accelerate a 2800+ lb car down the road. When the power is going the other way in a mechanical overrev, the engine is a lot easier to accelerate than the whole weight of the car would be. Hence, virtually no slippage in this case and the engine is toast with or without a delay valve!

Drive Safe,
Steve R.

The question is, did the rpms get over 9000 or not? If yes, then get it checked out, if no, then don't worry about it.

To be 100% honest i do not know. When i looked at it i know it was high, but i dont know how high. As soon as i realized i hit the wrong gear i shifted in neutral, and the revs droped very quickly. So im not sure exactly how high they got before i noticed i missed 4th.

Then I'd get it checked out. You may have cracked a couple of retainers, which would eventually drop the valves on your piston, and then you're looking at a valvetrain rebuild. Just spend a few hundred dollars now and get the retainers checked out, and then you won't have that problem in the future.

Buy one of these for next time, so you can recall highest rpm achieved. I have one and love it. It's great for track events, so I don't have to watch the tach when I'm shifting near the rev limiter.

since you are unsure how high the rpms went, i'd fork over the $150 or so to get your retainers checked. the car could crack a retainer, and drive with zero issues or CELs for months, then suddenly, WHAM valve to piston contact, and you are now looking to spend several grand for a new engine.


how long were you in the wrong gear? did you let the clutch out fully? realize it only takes a matter of less than a second to for the engine over 9000rpm. it all depends on how far out you let the clutch out. even the tach wouldn't necessarily have shown it since in such a case, the tach is going to be somewhat behind what's actually going on.


also, in the future, to prevent this from happening, do not use what's called a "death grip" on the shifter. when you are in 3rd gear, don't grip the shifter with your palm on the side of the shifter. this is what causes you to "pull" the shifter not only down but also towards you. instead, place your hand over the top of the shifter and pull it straight back.


watch my video here. notice when I shift to 3rd, at first my hand placement is EXACTLY what it SHOULD BE for a 3-4 shift. (however, once I go to actually shift, i move my hand to the death grip position, which is what you SHOULD NOT do) i'll make another video like this, and use proper hand placement next time.

I was in the wrong grear for less than a second, and i would say that at most the clutch was 3/4's of the way out.

it's honestly hard to say. since you are unsure of how high the rpms got, it's going to be a crap shoot. $150 now, or the possibility of several grand later?

FWIW you could do a valve adjustment as well since they'd be going in there anyways.
