i was riding with my friend in his mustang one day when he did the same thing, shifted into 2nd instead of 4th. except it didn't hurt his motor, his back wheels locked up and and the car went into a slide. i'm just glad my friend had good car control because there was a like a steep hill in the side of the road with trees and we were doing like 80-90mph. it was one of the scariest things ever.
 
for real though why were you doing 100 mph in 3rd! it sux that you miss shifted and didnt catch it before your car became royally screwed, i hope its just bad timing, even though bad timing is bad its a helluva lot beter than bent valves and having to buy a new head or rebuild the one you have now.
 
Dude, a head rebuild is not hard. All you have to do is make your own, take off the head. Make you're own ghetto tool.

Hey bro the same thing happened to me, for some reason my wheels locked or i couldnt brake and my car just slid like hell, i had to reach for the parking brake to avoid a collision. But ill tell u what, if your friend in the mustang does it anymore, he can say bye bye to his engine. Having bent valves is not a good thing.

Yeah bro 4th gear seems very hard to shift into sometimes..i never meant to shift in 2nd, but it just happened. The car just made a big roar sound (over reving) but as soon as it did that i took it out of 2nd and just put it in neutral, and was kinda hoping everything was alright..too bad the car just shut off. I really do hope is just bad timing, the mechanic who checked on it said it sounds like bad timing and misfiring, he thinks itll be just a bad timing but he said just incase your valves are bent, i better be looking for a new engine. So i hope for the best, i dont think i will ever shift into 4th gear at high speeds ever again! I regret every second of that terrifying boosting trip. Had i just stayed home and watched some porn id be better off.

Edit: Hey laserspeeddemon, thanx for the pictures, i think i might need these if i decide to this on my own. 1 question though, was it hard for you or was it a piece of cake?

Mustang engines are non-interference aren't they?
 
Timing errors in these cars are bastards. More then likely its bent valves. Take a loan out and swap it for a 6 bolt. Then youve got yourself a fresh engine and a basically brand new car.

On a side note, i went 4th to 2nd before, but my foot was hovering over the clutch and engaged it in a split second. Gotta be careful bro.
 
The reason you car seemed like it could not brake is because our brake boosters work on vacuum. Try slamming the brakes right after you boost. It seems like we lose all power brakes for a second. Then the boost goes away and we get the vacuum and our brake boosters activate. This is true for 1g's, I dunno about 2g's....

Anyway, if the engine is not turning, then there is no vacuum.

As much as i would like a 6 bolt, im still hoping my engine turns out ok, and be only a timing problem. However, chances are the valves are probably bent but according to the mechanic who took a peek at the problem, he said its most likely ill just need a new timing belt, if the car still doesnt start..shaking his head he said "buddy if your valves are bent your gonna need a new engine".So im gonna have to wait and see when he actually gets his hands dirty.

And laserspeeddemon your right about that, thats why the car wouldnt brake no matter how hard i pressed, it seemed like the brakes were done, i had to pull the parking brake to avoid running on to the sidewalk and possibly wrecking my bumpers or some other damage. So my friend who was with me told me to put into neutral and pull in the neighborhood to our left..we had to wait for the cars to not appear at all so i can make the move since the car would only move like 2 MPh when i put it in neutral, from there we had to get an extra person to help us push the car up the hill, it was kinda funny the guy was like "man this car is light..you both watch out i got it..than all of a sudden car goes flying back like 7 mph and hes like oh shit stop! PULL THE PARKING BRAKE!!!"..we actually had a little kick out of it..but that didnt last for long cause i had to go home with the burden that my car is dead.

yeah, they are. i wish dsms were non-interference since the timing belts are known to go quite often.

yeah i heard alot of bad stuff in terms of "reliability" about DSM's, but i never really bought all that

Me either. I owned a 1990 GSX for 3.5 years, lightly modded, with 90k miles in 1998 and never had one problem. Hell I didn't even change the oil more than once! This 1996 GST hasn't had any maintainance issues outside of ordinary wear and tear through the two previous owners, and is decently modded at 58k miles. My girlfriend has a N/A 1997 GS and it's also never had any maintainance issues beyond a clutch going out at 70k miles.

Anything will break if you abuse the shit out of it. When I rent cars I tear them up taking sharp turns at high speeds to tail slide, run all speed bumps at high speed, launch railroad tracks and small hills at 90 mph to get air, etc. Never could break one of them either. Of course I'd never buy a former rental either!

Um what the hell were you doing going 95-100 in 3rd gear? thats like right at the redline isn't it? Unless the 2g's are geared deferently. And as far as I know, there not.


But holy crap 2nd at redline YEA, um your valves were proably floating better than a well i duno what, but you get the idea.

Your REALLY lucky you didn't end up with a connecting rod sticking out of the block, or knowing for a fact that you just trashed your valves & pistons. Which you still may have.
 
like i said before, i was testing my GST, i was redlining every gear, and yes when i tried to shift in 4th it fell in 2nd..and car shut off. It could be anything, in terms of timing, bend valves, or even something else. But as far as my mechanic is concerned, it seems like my timing went bad, and that i will have to replace. But who knows, i wont find out till tuesday or wednesday..cause i still gotta get the car towed to the mechanics house so he can do it over there for me since he is not gonna charge me that much..he cant do it in his shop.

So heres the breakdown:

If im lucky itll be timing issues
If not, i guess were looking at a brand new engine..:cry:
 
yea wel if the car stalled out immediately when you hit second you probbably just jumped timing. but still you said you were shifting into fourth so you were actually at 100 mph in 3rd wow! still miss shifts happen but im pretty sure you were already redlining if you were doing 100 in 3rd!

Edit: sorry about posting it again but i still cant believe the 100 in 3rd i test drove a 1g and the max i got up to was 60-75 before it reached like 6k rpms and i shifted
 
i've noticed everyone that is suprised that he was doing 100 in 3rd has an awd. isn't the gearing higher on the fwds? i thought i heard that before. his speedo could possibly be off too. mine is off by like 10 mph at higher speeds.
 
Wow this is amazing. I did the exact same thing this weekend at the track. It would not go into 4th for some reason at all. It did however go into second very easy? This was at around 90 or so. I pulled the head off and I have one bent valve. Thats right only one. The roller rocker popped off on that cylinder, and hit the piston. I don't know how at this point how the other exhaust vale isn't bent. I took the head to a local machine shop for a new valve. I will need to get that replaced and I should be good. Should have this running before the end of the week.
 
Whoa now i feel like an idiot because everyone is surprised i was doing 100 MPH in 3rd..I was redlining every single gear and i can almost swear to got i saw the speedometer go to 100 MPH. But then again i could be wrong, i was probably doing 90-95 mph...i know its definitely not any less than this. I still keep my word, i was doing 100 MPH in 3rd, but than again i could be very wrong, after what i had to go through when i stalled, maybe it has left afteraffects in my brain that im begining to see things in my head..any ideas?? I appreciate your guys help soo much..maybe i was doin 95 MPH? Can anyone clarify if it is possible to do 100 MPH with me shifting to 4th (or atleast trying to) at 7500-8000 RPM in 3rd gear (cant remember when i shifted but it was definitely redlining).

FWD's do have longer gears. 100 in 3rd doesn't sound to hard to believe.

Yeah this just happened to me on Saturday. Its like it wouldnt go into 4th for some reason at all and instead it easily went into 2nd and than made a loud roar of the car overreving..ofcourse i instantly put the car in neutral as soon as it went into 2nd...it was over..I had to lift the parking brake to avoid colliding with something and push the car off the road. My car just flat out shut off on me. Im still praying its only my timing..but the truth is from what i keep hearing..one or more of my valves are probably bent. I guess ill find out for sure. Sucks that happened to you too..i hope it all goes well for you.

i said i dont believe you did it unless you were redlining thankyou for confirming you were indeeed redlining and it is possible because i was at like 70 at 6k rpms so 2k more rpms is a big diff.

You my friend are part of the reliability problem. I imagine the GSX has died already or will die some day soon. These cars last fine if you take care of them.

Why would you go 3,5 years with only 1 oil change????

To the original poster: You may want to think of a different mechanic. He is going to charge you to put on a new timing belt to see if the valves are bent of if it skipped time. I can tell you if it skipped time for like 20 buck at most. In addition to wasting your money he says you will need a new engine for bent valves????

Take the car some place else (home if you like) and we can help you check the cam timing and if need be pull the head. It isn't that hard and you can't really hurt anything pulling the head....just gotta line everything up when you put it back on.

Well, my GSX drank quarts of oil on a regular basis. I once drove 700 miles and had to bring a case of oil with me because I went through 8 quarts along the way. It seemed some of the oil was being expelled through my exhaust according to somebody that was driving behind me...there were no visible leaks and when parked no oil was left on the ground. I figured since I always was putting new oil in the car, why bother changing the filter.

As for why I didn't get the oil consumption looked at? I confess, pure laziness.
