help needed! gearbox/clutch problem!

Why not?
It is a known fact that a short shifter will increase the wear of the transmission. Also it is a known fact that a solid motor mount will transmitt all vibrations and shockloads through the transmission instead disappating it through the chassis.

do you really think a mount and a short shift would to such damage in a very short term?! Comon the guy had is car for like a year and ran in a very specific problem due not to his mods or driving, but to the weak tranny we have.

Brian lost is third with his car, many others did too. I personally literrally exploded a tranny on my 3. That tranny is wicked weak and there is no way all the tranny we see failling are due to ''spirited'' driving! (gun)
 
If he drove "spiritedly" enough to break an axle, then he drove it pretty hard.

Also, I like how you deleted all the stuff that you did to your car in the first post. If you don't think you did anything wrong, why delete it?

Known fact that a short throw shifter will increase wear? How do you figure that.?? (boom07)

You do know that it shortens the throws of the shift by adjusting the linkage on the shifter it self that is attached to a cable!

I just don't see a way the SS will harm a tranny.

I also think that most of the few 3rd gear problems have either been freak defects from the factory or from abuse.
I can definately seeing so slicks destroying a tranny with a bad launch.

From what I read here I'd say it is the latter.

I have about 30 1/4mile runs and alot of sprinted driving and about 3000 miles on the turbo and no problem with the tranny besides a slipping clutch.

The tranny is weak, there are plenty of pepole with no mods that have lost a 3rd gear for no reason either


Read what I wrote. There is little to no proof that it is weak. If so I'm sure I would have needed a tranny along time ago. I have had and dyno'd almost every mod there is as well as others with no problems.

There have only been a few with power that blow it up and most were not the brightest of the bunch.

There has been brian with the turbo and I believe his was a defect as he stated problems before the turbo.

So I think there is more proof that the tranny is not weak then you have that it is.

And I'm not saying it is the strongest out there, just not as weak as you state.
 
WHOA WHOA... guys guys.... calm down everyone.... i dont want to make problem here....

lets sort this thing ok?

3rd gear is usually the one hurt fastest, in pretty much any transmission. Thats like asking why is the sky blue.

s*** man... with all due respect, your're very rude :) not everyone has the same knowledge with you. especially stoopid guy like me.... and if i dont knoe better than you, that doesnt give you the rights to speak rude to me...

let me explain...

i deleted the first post coz i think the analysis was silly.... i mean irrelevant now.... complete has nothing to do with my race, semislick, engine mounts and 10runs...

i can post it up back if you want... :)

i delete everything in my signature, cost i'm putting everything back to stock at the moment... as i need some extra to buy new tranny.... none of anyone business anyway :P

i have nothing to hide.... i came to the dealer with all my mods.... didnt you read? so what are you talking about with me having something to hide...

NOW, my car is back from dealer.... and here is the result... dealer covered worth of $1500 damaged... the noisy CV joint... defected.... and the right hand drive shaft (they said it shouldnt shattered like that), and the engine mount.... which was bent... not ripped... they suspect is the was they put in the screw....

anyway... with the gearbox, they not sure that they gonna cover it, and
i cant wait.... so i better find a wrecked mazda3 with good gearbox....

anyway, i'm sorry if my problem and my thread cause arguments or offend anyone including you in such a way, i dont mean it to be that way.... i just want to share my problem.... if i cant, you could've told me nicely.... i dont see your post being helpful at all... but its ok.... internet sometimes tricky.... its a place where ppl can say anything they want without facing the consequences.... probably thats why some ppl cant be nice....

anyway.... the gearbox opened at the moment, and the mechanic even said its no damage what so ever on the gears... all the gears.... they still trying to figure out whats wrong....


^_^

the mechanic that i know was reading this forum, and he say its irrelevant... that should put stress on the diff... not gearbox....

i only had the rear engine mount for 2 weeks...

have you seen the short shifter in mazda3?

semislick only had it for 2 weeks too....

so i thought i'd delete it....

but let me know if you want it up again... :) i still have a fresh copy in 2 other mazda forums....

FYI its been up there for the world to see for the past few weeks... just ask everyone that have read and give me POSITIVE suggestions and when i'm still trying to figure out what happened to it, i didnt hear anything from you that time... only until now when i'm done, then i hear you talking...

i dont think that helps anything.... but anyway, its ok... you're free to say what ever makes you happy.... i'd just think its rude... :)

and I DONT THINK I DID ANYTHING WRONG... :)

i went to dealer with all the mods, and tell them the same exact things and even show them this very thread... this was few weeks ago when i still have everything up....

remember that no matter how many knowledges you have, you wont be recognise if you dont know how to behave....

respect is not a previlage.... its something that you gotta earn....

cheers

Absolutely. What is the design of a short throw shifter, to shorten the throw of the shifter to decrease the time it takes to shift. What is working between the times of the shift? The synchros, there design is to slow the next gear down enough to engage it without grinding.
By decreasing the time the synchros have to work you are increasing the wear of the snychros and dog teeth on the hub. The synchros don't have the time to slow them down properly. They have the hardest and most abusive job in the transmission already, and decreasing the time they have to work just accelerates their wear.

You really shouldn't be posting on things you have very little knowledge about. It would be best to save the speculation for another time.
You have no proof of this only a theory in your mind! (hah)

If you can't help don't post, you did give many a laugh though! (hah)

uuummm.... You are right, it's just a theory I came up with. Thats why there are Tsb's about it on other vehicles..

How about you tell me how it does not affect the wearing of the synchros.

This is good advise, I would also add to inspect engine mounts. If the tranmission is too far to the front/rear, it may also cause the pop out.

Your clutch is going, thats why the tired gear appears to be slipping. The Gear popping out during deceleration means either main shaft is damaged and/or 3rd gear cog in damaged also. You will have to remove the gear box to inspect this and while this is being done the clutch will have to be replaced. Running slicks on a stock clutch at a drag strip will result on premature clutch wear.

Advice: drain gear box oil and inspect it for metal fragments and chances are you will find quit a bit. .02 Good luck.

Really there are TSB's for aftermarket SS's!
What vehicles are these and one thing to add to your theory is we are talking about a Mazda3 here, not other vehicles that you are specutaling about.

Okay. Again, you are right.
Mazda3's have the only manual transmission in the world that don't depend on synchros to slow the gears down. And since they don't have them, they are not affected by the time frame between neutral and the next gear being engaged. In fact, I heard on the internet you don't even need to use the clutch because the transmission works on a principal called F'n M.

I'm still waiting for your answer to my question.

Common sense is your answer. Read my first post.
You can't just say something is fact yet have no proof. Show me the TBS's for the Mazda3. Actually show me other cars that have problems with SS!
 
I have an idea for you. Search. This is not a crazy off the wall notion. Mazda3 is not unique with this. It is inherent to all SS.

I don't know how to explain it to you further and even if I did I don't think you would understand it. If you are around Albany Ny let me know. Right now I have a Vw Golf's transmission laying on my bench in pieces at work. The reason? Grinding into third gear, why? Because the synchros are worn, and guess what...he had a ss.

Thats a good reason for third gear to go!

So if he didn't have a SS would you have told me that he just shifted too fast.

A perfect example of why service techs know very little and are quick to try to void waranties.

Your right I wont understand you opinion or reasoning so we will leave it at that. (hah)
 
Why not teach me with your great knowledge? Come one, you must be really smart, you bought alot of kits for your car. Teach me, I love to learn.

Lets take it to pm's to stop cluttering this thread.

ok.... here we go...

Gearbox is pulled apart, found the problem:

the 3rd gear chipped, synchro and the hub is broken too...

hope this will clear things up.... my mechanic said there is nothing to do with the Short shifter and the cable movement is the same with stock shifter.

atm, i'm rebuilding it and do treatment on the gears with 'nitride' to make it stronger.... still waiting for the parts from japan...
