Shifting DOWN into 2nd Gear? Grinding, etc?
#26
yeah i believe you're right it definitely could be the synchros then he'll have to worry about 4th and 6th gear going bad as well! I had a buddy having the same issues and when finally got to shift he'll get a huge kick, almost snapping your neck!

If the problem gets so bad that you can't downshift anymore I say get it fixed under warranty. if they try to say it's abuse I would pull out the bullshit card. How can it be abuse if so many people have the same issue, this will be your defense. If you press the issue with a Mazda regional rep, I'm sure they will cave. It's cheaper than dealing with a lawsuit in which their service records can and will be subpoenaed by the plaintiff's lawyer. This will show that the second gear synchro sucks. Mine is having a similar problem but only when I downshift b/w 50 & 55. If it gets to the point were the up shift to third grinds or I can't down shift to 2nd at all without grinding no matter what rpm off to the dealer I will go.

I don't really trust my mazda dealer as last time I went there for an oil change they didn't rpleace my oil or filter.....and I had to argue with them abou it........they told me I was lying and it was my word against one of thier head mechanics.......unfortunately for him I had etched the oil filter a bit before I went in as it was the first time i had been to this mazda dealer as I had moved........they gave me my money back and I told the mechanic he was a fucling dick.......I don't get my stuff done their anymore.

I have actually found that rev matching with clutch in before engaging into gear DOES help significantly. Usually I will rev a bit higher than needed to allow for better speed match when the clutch is let out. Above it is stated that this should only help with the clutch out? Also, don't underestimate the value of being smooth.
As far as downshifting into 1st, I don't even try unless I'm going under ~8mph, and even then I rev that ***** like hell before engaging the gear.

I've seen a few up-shift problems here on the forums - anyone else have trouble - I mean, sometimes it's IMPOSSIBLE to shift down into 2nd gear above 40mph - going down thru the gears?
My kar 'supposedly' has Royal Purple in the tranny (Can't confirm the dealership actually DID the fluid change - felt NO difference in shifting afterwards), and 30,000 miles.
Thoughts?

Gearbox change
Hi
I bought my RX8 with about 6000 km on the clock. I had the same problem. Luckily i was under motorplan, so they changed the gearbox and clutch for me. The problem stopped for a while but has started again. The mechanics at the garage have told me that the gears are paired to certain ranges of speed that the car is travelling. I have also heard rumours that gear ratios are slightly different depending on which country you live in.

I had the same problem, even after switching to synthetic tranny oil. The problem with yours is either a bent fork or the second gear synchro is **** (as other people have experienced). I had my transmission replaced under warranty for it (my synchro was bad), and I'm about to get the same done for the 4th gear on my new transmission.
Word of advice- if you have a short shifter, remove it before going in. The dealership will do all they can to blame this on your driving rather than admit they put shitty transmissions on our cars.

I'm starting to experience this same issue. If I try and upshift into 2nd gear at high rpm's it grinds as I try and get it into gear.
It doesn't lock me out of the gear, but grinds as it's going in. At first I thought I might have mis-shifted but the clutch is completely in....
sound like 2nd gear synchro?

There seem to be a decent amount of related problems.
Bad/weak synchros, bad clutch pedal, bad shift forks
I have very few shift issues 1-6 but my car doesn't like to go into reverse. It's not hard to get into reverse, but it usually takes a 1-2-5-R shift to get it to go all the way in. Otherwise, it'll engage with the synchro and sit there. When I let out the clutch, it won't grind. It'll just zing - it would grind if I was pushing on it probably. Driving in reverse feels clunky, but all the forward gears are strong.
Anyone have any leads on decent tranny parts? This is something I want to start pursuing for when I destroy a tranny and can't get warrantee coverage.

RX8 and a Truk....
Thread Starter
Do you happen to have your paperwork? Dealerships around seem to tell me ANY PROBLEM I bring in is unique, and they cannot find another SINGLE RX8 with like-issues. If I had something to show them (a scan of your repair order? Repair order number? or something?) at least i'd have 'ammunition', so to speak.
Thanks

I took mine in on Thursday for this issue. The service manager went for a spin with me and sure enough....GRIND!!
I got a call yesterday: A new transmission has been ordered.

The same happens to me. Grinding while upshifting to 2nd at high RPMS.
I really want to bring my car to the dealer, so they can look at it. But I got a novice question, how much does it cost for them to inspect it? Do I need to tell them specifically where to look and what to look for. My car is out of warranty, so whatever problem they find will have to go through my Extended (Third Party) Warranty. So how much is a typical diagonosis at a shop?

my money is on the master cylinder plunger rod at the pedal needing to be adjusted. It takes a 12mm wrench to break the holddown nut, you can then turn the plunger rod by hand to remove most of the free play so that the master cylinder piston gets the full travel from the pedal, which in turn provides maximum pressure plate release. You want to have a small amount of clearance though. Adjust the plunger rod by hand until you feel it start to tighten up, then back off a turn or two and lock the nut down
