J.T.'s 3.2CL

Last night I missed the 3-4 shift. I shifted into second gear accidentally and the revs shot up but I pushed in the clutch as soon as I could. I didn't see how high but it couldn't have been good. I consider myself a decent driver but I just got to anxious and screwed up....Please no flames... The car seemed to be perfectly normal afterward and today. A little while ago the check enging light came on..... I unplugged the battery for about an hour and now it's off but it's possible it may come back on. I know there is probably an over-rev code logged in the computer.....How do I MAKE SURE I get that code outta there incase I need to go to the dealer? I think if something major was wrong there would be some sort of indication (blowing smoke,knocking,etc...) but it's possible the light came on for another reason.

Thanks, J.T.

ur fine, im a new stick driver and went from 2nd to 5th by accident. bogged the engine, but all is well. Also did the same thing u did once.

Crazy Bimmer

he didnt skip a shift, he overreved. Acutally you never know, you may not even overreved and should be fine. I dont think there is a real way to know if you did or not. Just be happy your car is running fine right now.

But it doesnt hurt to get it checked out.

stick noobs....

Amoeba

thats right i am a stick noob

What is the concern...unless of course you have no rev limiter...

Scrib

Rev. limiter won't help on a downshift...

Scrib

And you drive an automatic. Your point???

CCType-S

Sound like you have a bent valve or something.

Slimey

Why do you say that?

Based on the info given, I'd guess this is no biggie. Since the CEL lit, if it were me, I may take it to the dealer for a check. You're going to have to take it in anyway, sooner or later, for the new timing belt tensioner replacement and/or waterpump recall campaign.

Or course you can also get an OBD-II scanner for like $100 and read the code yourself (or go to AutoZone, so I've heard).

civic4982

should be fine... I did that once... dind't let it rev all the way up before pushing the clutch back in so...

First Auto in 15 years...

Scrib

I see..

Once you get to be your age, it becomes a difficult task.

Ah well... I've still got a few years to go.

Your engine should be fine if the overrev was just for a very short perio and the RPMs at third were not near redline.

In many cases the engine just blows as soon as you overrev. You might be lucky this time. I am not sure about the overrev code, but if I were you i will check at any place but an Acura dealer.

Good luck, and careful with those shifts.... coming from third to second at high rpms is very hard though; I dont know how would you engage it hardly... its noticeable.

zamo

I drive stick since I am 14. Where I come from, auto trans cars count maybe as much as 0.15 % of all cars.

Wires

The computer does log the over-rev code. So, if you are concerned about anything, it's worth your while to beg, borrow or steal an OBD-II tool and clear that one before it hits the dealer....

Titand19

hey man how did you do that? normally that over rev happens from 5-2, interesting. must be some good green

synth19

Do you know what the speed you were driving at? Were you at a HIGH RPM range and that's why you were shifting into forth? Or was it kinda like in between 3-4k??? Because if it was the latter, then I doubt you have anything to worry about....probably then just an over rev. Now, if you were near redline before downshifting.... uh oh... but sounds like things are okay.

J.T.'s 3.2CL

Thanks to everyone who responded so far. Is there any other way to clear the over-rev code other than with the ODB II tool? If I get one will I DEFINATELY be able to clear the code myself? Does anyone have a link to the one that would do the job?

I was in a very competitive race got anxious and was shifting too hard I guess... :shakehd: I'll make sure this never happens again. I could use some green....LOL...

J.T.'s 3.2CL

I decided at the last second yesterday to go to the track.....I was right near redline when I shifted. I'm very lucky it didn't blow it up right then.

bullaculla

If I am ever not sure on a shift, I just put the knob in neutral, let go and then pull it straight down. hits fouth every time.
you really have to pull it to the left to hit second. just bring the knob straight back!

BTW, your situation sounds fine tho. if you overrev past redline, and the valves float, it'll just bend a valve and blow your engine.

types1967

if the car runs very rough you bent a few valves and the chk engine light will come back on after a while since you unplugged it.if it doesnt come back on your ok

1killercls

Yea...that's it...sure.

Actually the six speeder was not available when I bought my auto.

I had an over-rev problem, NOT MY FAULT. Here's my post a while back:

If it is running fine you are most likely fine. I have done it before and at the track; watch and listen in the below video (just when I appear to be below the display board).

CL-S6 Blown Shift

I got back on the clutch right away but the revs were over 8000 RPM when I looked down. When I read the code it had 81xx RPM logged with the freeze frame data associated with the code. One good thing is that the type of clutch we have will slip a little so the revs didn't go as high as they could have as quickly. I also did a compression test a few months ago and all cylinders were between 200 - 230 PSI so obviously no damage occurred.

tmk70

Don't stress out...you'll be fine

KissMy_Type_S

Just went to the dealer today for my oil change and FINALLY my check engine light came on while I was there for once. I actually got to talk to the tech and told him he'll find an over-rev code (went to gas cut-off, about 7300, once going into 3rd) he laughed a little and erased it for me said not to worry about it and it wouldnt show up again.

BTW not to hijack your thread or anything but the CEL came on because it read a misfire and the tech said that with the 6spd its common because the computer is very sensitive and if you bog down the engine or something along those lines and the computer senses even the slightest change in speed from a cylinder it'll throw the misfire code, incase anyone is interested. Not sure if thats right or if im explaining it right...

bigman

My friedn over revved his 6 speed and he had misfires, thats why the CEL came on. But when he miss shifted again he had bent rods and shit

zamo

damn, so if your car is fine, what was that noise which apparentrly was loud?

KissMy_Type_S

OK ... someone is gonna have to clear this up for me. I cant even count how many times Ive gotten the revs up to JUST before gas cut off. Exactly how badly are you over-revving and exactly how does that happen to that extent? The one time I did "over-rev" I hit the limiter at 7300. I thought thats what the limiter was there for to prevent any worse.

Scalbert -- How did you get it to 8 grand? did you remover the limiter somehow or am I totatlly missing something here?

No this is different, just cause you hit the rev limter doesn't mean you over rev'd the car. You hit the limter that's in place so you don't over rev, that's why the fuel cuts off. When you over rev, you have to bypass the limter like when you downshift a gear.

Jens H.

Once you unplug the battery from the car the ecu forgets anything and everything .SO the code the history on how you got it is all bye bye
Drive the car and report back if you see the CEL again .Then we will take it to the next step if the light stays off consider it a scary moment you learned a bit about driving stick shift cars .

Jens

scalbert

Don't mistake the bang on the bleachers for the mis-shift and the over rev. He can distinctly hear the engine rev up quickly.

scalbert

The rev limiter just protects the engine from reving too high through acceleration by cutting fuel. If you engage a too low of gear there is nothing the ECU can do to help as this becomes a purely mechanical function.

KissMy_Type_S

AH HA ... Gracias.

bigman

Something should be made for noobies that drive stick so that the clutch will automatically engage, causing the car to cost if it picks up the downshift into to low a gear

bullaculla

...or a slipper clutch.

stejus

I'm no noobie to a stick and I've miss-shifted 5th to 6th and went from 5th to 4th at least 4 times since May 03. I noticed it immediately while letting the clutch out (only partial). As soon as I felt the lunge forward, I buried that clutch. I'm sure I never even came close to hitting 7K on the tach!!

I blame this on the natural pull to the right (your shifting arm) and the height of the stick and armrest. Maybe a shorter shift would help but then the cup holders would be useless (the drinks are always in the way!)

I am RobG

yup same thing happened to me at e-town for acura wars last year. 3rd right back into 2nd as i was slamming 4th, rpms shot up to about 8 then i put my foot on the cluch and my car's still fine

jproy

unless you have apparent damage you should be ok. I used to have a '95 accord 5-speed. one time I was driving from Lafayette la to Destin fl and was on the rev limiter at about 6300 RPM in fourth doing about 115-120 MPH. I was showing off and went to grab 5th and somehow got third. when I made the shift I never pulled the acclerater off the floor and dumped the clutch. the tachometer blasted past the 8000 RPM mark to what I guess must have been something like 8700 RPM before I could get the clutch back in. SCARED THE FUCHING CRAP OUT OF ME!!!! I thought for sure I had blown up the motor. A true testement to Honda-- the car never missed a beat and ran fine for another 80000 miles before I sold it. no check engin light either.

sharing my experiences,

Jim
