I just bought an '07 with 33k miles. I am having problems with reverse. It does not want to go into reverse and even after it does when I start backing up the clutch or tranny, not sure which, starts clicking. When shifting back into 1st from reverse there seems to be a pop and then no problems. I am not having any problems with any other gears.
That problem is most probably ur clutch or flywheel is worn out....

i recently wrecked my A4 and picked up an RX8, how funny. My friend sold me his 2005 RX8 M/T with 30k miles, called MazdaUSA and got the warranty transferred over, so the motor is covered until Sept 2013 or 100,000 miles same with the trans and the clutch pedal (that was a curious one for me, never heard of a clutch pedal being covered).

thank you! I got it for a steal, it had some of the typical problems that i've already fixed like re-soldering the temperature ****. The clutch pedal squeaks so i'm gonna have the dealer fix it, and i need to have them flash the PCM and take a look at the motor mounts since the idle is rough. Also i think i might have a bad wheel bearing in the passenger rear but i can live with it for now.

Lately my car has been making a slight grinding noise while in reverse and when I let off the gas pedal in any gear. It also slightly grinds while letting out the clutch from 1st to 2nd gear. I took it into get it checked out and they looked at the clutch and said its in great shape so they think its the transmission. They are tearing the transmission apart today to see if they can find the problem.. My car is a MT 2004 with 53,000 miles. Unbelievable that the transmission is going bad already.

New tranny oil seems to have helped a lot. My car used to grind hard when shifting third to 4th, but it has been progressively getting smoother, and now almost shifts without a hitch. It did take nearly a year for it to change, but I feel much better about it.

Props to Red Line MT-90
Just posting a quick note to forum with positive feedback on Red Line MT-90 75W90 GL-4 Gear Oil. With over 100K on the clock of my 03 build MT, I have had a chance to experiment with a few different products when changing tranny fluid.
I just put Red Line MT-90 in for the first time last week and I am amazed. It has DRAMATICALLY reduced the amount of gear whine I have grown so used to over the years - at times so loud in lower gears that it was an even more dominant sound in the driver's cabin than my hi-flow Mazdaspeed dual exhaust setup.
Literally surprised me so much my innate first reaction was to assume something was wrong with the car.
So far I have tried it a couple of mornings with temps just below freezing and as high as 60 degrees F and have found no problems with notchy shifting or any other concerns whatsoever.
It gets a big thumbs up from me - well worth the cost!

I just bought a 2005 RX-8 with 58k miles on it about a week ago no warrenty that I know of. It sounds like the gears are grinding or something? When I shift above 6rpm from first to second it grinds same with third to fourth but it never does it below 6 rpm. Anyone know what would cause this? I really do not want to have to replace the tranny seeing how it will most likely be out of pocket..

It will probably eventually be replaced. You can try replacing the tranny fluid with Redline MT90 and see if that helps. I recently had to replace mine after reverse went and then 1st was going.

just get and OBD tool to check what code is it running....
most rotary workshops would be able to help u diagnose...
anyways, i thinkz this a thread for transmission issues though...

I have read through this entire thread (mind you it took a couple of hours), and I just can't believe all the tranny problems other people have... with that in mind, I'm a little relieved but also very enraged that a problem of this magnitude hasn't really been fully addressed by mazda. Thankfully I've had a very good Mazda service rep that actually tries to help out and relieve alot of costs on me.
When my 8 is at operating temp, I can't shift from 1 to 2nd gear above 5k rpm due to grinding and resistance. I've done testing to where I try to force the shifter into 2nd gear at 6k rpm and as the RPM's start to come down past 5k rpm, the shifter will then allow me to put the car in 2nd gear. I have also shifted slowly and paid attention to pushing the clutch all the way down. I realize that there are posts about grinding of 2nd gear but only when it's cold. This is happening when I'm at operating temp and been trying for hours. I am also unable to downshift to 2nd gear from 3rd or from 4th until my speed comes down to around 30mph (tested). This makes me believe it's an issue with 2nd gear alone. I've recently had my clutch, input shaft, and throwout bearings replaced. This repair was done because the pin had exploded and apparently there was some melted metal also taken out no doubt from the bearings. I've read that it might be either the synchos or motor mount out of alignment but I'm not sure what the motor mount is? Is it the component that mounts the transmission to the flywheel? The Mazda rep said the something about the transmission input shaft was off alignment by 0.002. but there's no mazda spec on it. so he said it was fine.
I'll be updating the poll in the other thread but wanted to see if anyone had a solution for my problem. I'm driving my 8 as of right now with no problems due to the fact that I'm shifting from 1-2 under 5k rpm. Note: Shifting of any of the other gears I have no problems with. My manufacture date is 05/03 with about 105k mi. Also has a brand new engine that was installed recently. Any help would be appreciated. I'll post some more info in a couple of days when I take the car in.
