Last night I was out driving around and I accidentally ground my gears REALLY bad trying to go into second... I don't want to get into how it happened. For the next twenty minutes I couldn't even get it into first gear and barely into second... I was told I chipped my synchros and driving it around would wear them back into the original shape... I've been driving around and it's getting better however the shifting just still doesn't feel normal. Should I give it more time? should I take it into the dealer? and If I do will that be covered by my warranty?

Thanks.

Double cluch the car the first few times from 1st to 2nd. From there on should have no problems. Good Luck.

3 or 4 people told me driving around would make it better. I'm located in half moon bay about 20 miles south of San Fransisco. Build Date is early 05 I think.... It's an 05 model year.

good news.

that # checks out... and you are not in the bent shift fork club...

relax... from now on make sure that the clutch is to the floor before you try to bang second gear...

food for thought ... slow is smooth, smooth is fast..

So if my car is shifting funny... will it drive off? or should I take it in? and is that warranty work? or out of my pocket?

I don't know if your trying to give me attitude right now I can't tell the tone of your voice online... I appreciate your help but I'm just trying to make sure I know what's going on and I'm not a dumb kid, so please don't treat me like one. Anyway I know how to deal with the dealer and my warrenty, and yes I've owned 2 cars before this one.

your ? is silly... if you have had two other cars... you should know that...

if you can duplicate the sound or grind to the dealer you have nothing to worry about...

i am not trying to harsh you out... if i was you would so know it......

i just answered the? asked.

Swoope - I don't see a TSB on this. Where did you get your information?

Searched and saw some people talking about tranny problems and bent fork related to 1-2 shifts, but nothing terribly specific.

My build date is 6/03 and that seems to put me in just about every problem catagory that's occured yet, but, I've been very lucky - no problems whatever - so far....

Just wanna know what to keep a look out for.

When you do a bad "gear grind", you're not grinding the gears and possibly not the synchros. What are clashing are the "dogs" and "slots" -- these are what engage to determine which gears are transmitting the torque. The actual gears in your gearbox are fully engaged, all the time. And the synchros help get the speeds of the selected gears closely matched so the dogs and slots can engage. So if you get a really bad grind, the synchros haven't really had a chance to do their job. The dogs and slots are fairly beefy features, but they can be damaged. They make a terrible racket any time they clash, so most people back off before there's serious damage. It's possible for a slight bit of damage to them to "get better" by driving, if there are burrs that get pushed off and find their way to the bottom of the case. You may see them next time you change your tranny oil. In severe or repeated cases, the ends of the dogs can "mushroom", and you will be locked out of a particular gear.

i dont think it was a tsb, it was a tech note or something like that.... but mazda was aware of the problem...

do a search for shift fork and you should come across it... you will have to go back a way..

if you cant find it send me a pm and i will help you look..

Oh no problem! It was on page 17 of the tranny faq.
Also got to read a very entertaining thread where you pounded Bart!

There's 20 minutes of my life I'll never get back... :-/

It's a pdf that's on Rosenthal's site, but it isn't linked to by their TSB / recall list....
Applicable VIN range: 100001 - 131251;

for anyone else who cares....

Don't you love that? The search function sends you a list of threads, most of which were started in 2003, are 30+ pages long, and the topic you want is actually a hijack that gets quickly cut off. For people new to this forum and this car, there isn't a lot of efficient help here.

To those whose profession seems to be sitting at home typing the word "search" 20 times a day, why not just stop replying at all?????

OK, /endrant

This is a useful forum, but I have found it to be less welcoming to newcomers than most, and more often than not, questions are answered with "search", suggesting that the only way to get help is to paw over pages and pages of old posts.

RX8Maine - my thoughts exactly.

Nothing against Swoope - unlike Mugatu, he does have a lot of useful information and is pretty good at ferreting out trolls.

I did a cursory search (maybe 10 minutes worth) before my first post in this thread and found nothing. I posted my question to Swoope b/c he seemed to be able to verify tdill8's VIN against the affected range very quickly. This lead me to believe he had the information close at hand, therefore, I asked him for it directly. I guess I was mistaken.

I am not a newcomer - I've been lurking for a long time. I have all the TSB's for the car and the shop manual in both the pdf and html formats. My post count is low, but that's b/c I generally don't post unless I have something useful to say....

Swoope is very helpful, his speech delivery makes him come off as a mean guy, but i think thats because english isnt his first language? Im not sure but anything swoope says is very useful.

Also, as mentioned before, what is the build date of the car, it should be located on the drivers door sill VIN plate. Get back with that information asap and we will be able to further pinpoint the issues you are having.

Swoope's advice made my car blow up and then I got home and found out that my dog was dead (also thanks to Swoope's advice).
