Default Prelude problem.. 5th to 2cd downshift ( oops? )

Posting for a friend :

I did a quick downshift from 5th to 2nd and my revs immediately jumped to around 10k I threw it back to neutral as I saw the needle fly WAY past redline and I heard a huge bang from my motor. The clutch pedal was "stuck" to the ground and I couldn't put it into gear. So I pulled over to the side of the road and manually pulled my clutch pedal back up with my hands and all of the stiffness in the pedal was gone and it wouldn't go into gear. So I had to have my car get tolled home. It was suppose to be a 5th gear to 4th gear downshift, but I did it too quickly and blame my own stupidity for this.

Here are some symptoms that I'm having with my car:
1. Won't go into gear
2. No stiffness in the clutch pedal whatsoever
3. Idle is fine at 700-750
4. When I rev it from 1k-2k, it vibrates the whole motor/frontend
5. Rev past 2k and the vibrating is still there but not as bad as 1k-2k
6. No CEL (check engine light)

Does anyone know what could possibly be wrong with the motor? (headgasket, valvetrain, rods, clutch assembly, flywheel, etc.)

I would say its your clutch assembly. Pull the tranny and look at your clutch/flywheel.

I have done the 4th to 2nd acouple times with my H22a.. Nothing broke thank god.

I think you may have spun a bearing too. I think CHK4TIX had the same issue when he revved up his old motor.

Can anyone confirm this??

Also, I think your clutch is trashed. You over revved it.

I hope I am wrong though.

Good luck!!

If he bent the valves it would not idle normal, and have a hard time starting.

sounds like something in the tranny is loose and the release fork/throw out bearing were knocked out of whack.

There is a reason why they call it, "The Money Shift".

I did it once. I always wondered how people could do it without knowing. Fortunately, I did it at around 60mphs. RPMs shot up to redline and I immediately pushed in the clutch. Now, when I downshift to 4th....I pull the shifter differently.

I don't know how anything could be "loose" in the tranny. If something is loose...that means it broke. I think it is the clutch that is trashed. OEM clutches are not designed to rev that high that quickly.

Let us know how it turns out.

i've misshifted once. shifting from 3-4 and i went into 2nd by accident. only time my h23 has seen 9k+ rpms. it happened for a split second because i also immediately pushed the clutch back in. everything seemed to be okay. *whew*

since the clutch doesn't seem to be engaging, then the clutch disc/pressure plate is screwed up. and the vibrations may be coming from that assembly now possibly being off balanced. there's probably no pedal pressure because the fork isn't engaging/disengaging the throw out bearing.

the spherical bolt that the release fork pivots on has broken in my tranny before and i had to rev-match my shifts to get the car home. i also couldn't come to a complete stop either otherwise i'd have to turn the car off, manually put the car into 1st gear, and crank it back up to get it going again.

i agree that your clutch is probably trashed.

you more than likely destroyed your clutch and there is a strong likelyhood you atleast f'd some valves

dont start it anymore, dont rev it, take it to a mechanic

Sounds to me like you bent the hell out if your shift fork, which inturn might have screwed up your clutch disk/pressure plate. Go look between the engine and the radiator at the slave cylinder, is the metal piece that is coming out of the tranny (that the slave cylinder pushes) loose?

As far as your engine vibrations go, how may miles are on the engine? Also is it just vibration or it there any tapping or knocking noise that you hear?

i did the same thing, except i went into 3rd gear instead of 5th when i was powering downhill on the freeway.

the clutch stayed down stuck like your's did, but i was able to pop it out by slamming on it a couple times. they car seemed to drive fine so i continued on my way. then the next morning when i started her up, i sounded like the engine wanted to die.
i ended up being a loose valve. so that was fixed by a simple valve adjustment.

sounds like the clutch on yours needs to be replaced..mine was fine(that was 30,000miles ago)

It boggles my mind how you can shift from 5th to 2nd. Even if i tried to force 5th into 2nd, it wouldn't budge for me.

Um 3rd to 2nd is easier than 5th to 2nd so dont give me that . Why don't you try going on the freeway and shifting from 5th gear at 60mph+ to 2nd, it's near impossible to move.

actually it's not as hard as it seems. like i said. not paying attention can cause that. hell i've grabbed it out of 5th and accidentally went to 2nd before. when people try to "force" the car into gear very rapidly. mishifting happens frequently.

take it to the mechanic so the car can be evaluated to see what damage actually occured. If you heard a bang you have valvetrain damage.

hopefully the clutch didnt shatter too much and destroy the disk.
