Add me to the list. 5th gear grinds at 70MPH+, occasionally up-shift, but mainly downshift. It does limit the fun factor a bit but I am living with it. But we need more support!

Yes you are right, I'm not the skilled mechanic.
So a mechanic should drop the transmission to change the seal?
Edit: I found in the workshop manual how to do that.one more time thanks for help,

possible solution for tranny problem
I had started the thread looking for answers to difficulties going from 1st to 2nd while at high revs and i think we've found the explanation: anyone having this problem, check your motor mounts, it shifted fine when not accelerating but held at 7k revs, but motor and tranny aren't lined up correctly for smooth shift acclerating when motor mount is loose or broken. broken mount could cause other problems over time, check them carefully!

Message to Mazda
Hey guys. I thought yall might get a kick out of my message to Mazda.
----------------------------
Dear Mazda,
I appreciate the new 2010 engine I have received in my 04' Rx8 due to the recall. I am extremely great full but I have a major problem with my shifting. For the last two years my 2nd gear has been ******* me in the ***. Now my 6th gear and reverse gear will not engage. I do not race my car, and there are absolutely no modifications on it. I'm just saying, it's kind of hard to do 'any thing' when I can't even reverse. I used to be able to get the Revs just right to shift into 2nd but I have given that up entirely and shift directly from 1st to 3rd. I have tried transmission flushes and ect. The problem started around 20,000 miles.
In conclusion, I think my complaint should warrant a new transmission or at bare minimum refund half of the cost because you sold me only 3 ******* gears out of the 7 modes that actually work.
Eternally your Customer,
Jacob Lemons :-)
PS: Bring back the Rx7 with more HP.

So I've read a lot of the threads posted here, I can relate to a lot of them. But, I
am still convinced, that my car has a different problem(s).
When I brought it in, I also mentioned that I had been noticing a problem, with my clutch.
Problems:
1) When I step on the accelerator hard, the clutch pedal goes to the floor (by it's self) for example, when merging on to the freeway on third gear.
2)When I shift from 1st to 2nd, past 3500rpm. It grinds and the gear wont go in until I release clutch and try 2 or 3 times.
3)Loud whistle like noise from transmission, when I press clutch it stops.
4)Inside cabin, driverside gets really hot where my right leg leans.
5)This is the worst! This one I cannot live with.
- When the car is driven for more than 10 minutes sometimes less than 2 miles.
The gears, will not go in. It seems as if the clutch becomes useless, even when I press the pedal down, the gears will not go in. (none of them, especially R) It's really frustrating, especially at red lights, hills, traffic... (you get the point)
If I force it in, it grinds.
Today, something different happened.
I was a drive thru, had the car in first gear and when I tried to take it out to put it in neutral, it wouldn't come out! Out of curiosity, I rev up the car to about 3k rpm, guess what!? The clutch engaged (by its self), and the car took off! even when I was holding the clutch pedal to the floor!
So, I am asking if anyone has any suggestions, or past experiences, and how they were solved. Advice as to what I should do.
Last time dealer "checked it" the invoice said: "Customer states a problem with clutch. Road tested, clutch seems fine. Quick engagement."
Also, if you know of another Mazda dealer, who has a better staff / service in bay area let me know ( I don't mind driving a little)

new rx7?
Be sure to check out the May issue of Road and track, in cars of the future... in 2012, Mazda is bringing back the RX7, with 16x renesis, set to go on current Miata platform, so will be small, light, hopefully for same$$range as RX8. The concept artwork is lovely, but ideally they should make the RX8 a true 2 door, 2seat, and put the 16x in that, update the body a bit.. meanwhile, good luck getting your issues taken care of;have your motor mounts checked, could be part of your problem.

I changed a new clutch, a replacement made by exety which is supposed to fit as the original from mazda which is also made b exety. I don't get it why sometimes goes easily into gear, sometime doesn't go at all unless I stop the engine. It is very annyoing. When i'm driving the gears change. When I want to put it into 1st gear it doesn't go all the time, and also same problem with reverse. Might be the syncronizer or flywheel? or just the clutch is not fitting properly? or maybe even worst, the Gear box has problems? thanks in advance for helping me with this

It sounds like the synchro, there is usually alot of fine tuning when it comes to aftermarket parts. The flywheel/clutch assembly may not be meshing the way it needs to with the new tranny. Good luck.

I thought it might be the synchro, I went for a check to mazda as yesterday it failed to start , so I thought it was the starter as I pushed it and the engine was moving, I forced started it to be able to go to the garage, and the checked, seems that my old mechanic was putting the wrong oil which caused the car to overheat ( Thanks to him...) got lucky that i went only 2 k with that oil and the engine did not messed up as it was fully synthetic oil, which is not recomended by mazda. Anyway they discovered now that there is a damage on the flywheel, and that's why I can't start the car, so maybe that's why doesn't go into gears, I must wait 2 weeks with out my 'love' and I'll have to see, I'll let you know, what will happen (if you care =) )

Hey Guys,
I have an '04 manual that makes a mild grinding sound when the clutch is not depressed, the lower part of the shift stock gets rather warm after driving, and shifting from 3rd-4th over 4000rpm's always grinds into gear and is sometimes followed by a burning smell. I also know that there is a mild oil leak in the gearbox, but the fluid was just changed.
Any theories what might be going on?
Thank you!

Tai-Stik- When you press the clutch pedal in does the sound get worse or go away?
How does the engagement point feel? Is it close to the floor or about mid-way up the stroke?
Easiest way to know is press the clutch pedal in, put it in gear, and slowly lift up the pedal and try to gauge when the clutch is engaging (you can hear the slower groaning sound just before the car starts to move).
And you mentioned a mild oil leak... is this from seeing fluid under the car?
When you replaced the fluid did you buy a new crush seal/washer?
I've reused mine a few times without issues, but maybe your seal is bad or the drain plug isn't tightened.

Hello people,
i was telling you about a noise last time at the rear of my car,
well it is the LSD which is almost dead, because of too much track days with no heel/toe help when i was braking.
i do it now since a year, but i guess damage was done already before.
i will try to put a R3 lsd which is 4.77 instead of 4.44, if too expensive here in france i will go OEM for my 2005 Sp model.
here is the noise :

they changed the oil , the air filter, oil filter. Seems that the engine is ok, no damage was made (thank God) . It wasn't starting, so they checked the starter, it was ok. The problem was the flywheel, so it will be replaced sometime today or tomorrow, I waited 1 week to bring it from Belgium :| . But as you know, one problem never comes alone, they said I might need a new clutch, even though I changed it 1 month ago. It wasn't original, it was a aftermarket brand, replacement made also by Exedy, as the original one. I did had hard shifting and sometimes not goin into gear, as mentioned in my other posts. I hope that it would be somethig else, because here in Cyprus the parts are too expensive. Usually I buy from Ebay parts, but they won't accept this . Anyway, I will wait till everything has been replaced, and I hope that my rx8 will run smoothly as it should.

-------> MEI fixed my rx8 yesterday, apparently the aftermarket brand clutch was not good, probably the presure plate, as it caused the flywheel to fall off from it's place. New flywheel, new clutch, oil change, air filter, oil filter, 1325 euro
. It's working smoothly babyyyyyyyyyyyyy. i`m so happy :-) but unfortunately the check engine light is still not good, it's a bad senzor, but i can't change it now 
anyway cheers and drink as I will drink tonight !

every time when i switch 1st to 2nd, 3rd to 4th and 4th to 5th gear on high rpm it's scratching
i gotta step in the clutch and hold for one or two seconds then the rpm fall a little bit and i can shift without any scratching
does anyone could point me to the right direction so i won't have to remove my tranny and ask to someone take it apart to find the problem if sometimes i wouldn't need to
one friend told me that could just be the shifter but i don't know about that
thanks guys

i changed the oil in my tranny about a month ago and i add royal purple to it, so i was talking with a friend today about the grinding and he told me that could be the royal purple the reason, he told me that he already saw lot 8's that had royal purple on the tranny and after that they've been grinding
i will change my oil in the coming week and see how the tranny reacts
