For 1st, do you have to rev it a little bit when it doesn't go in and then it'll go in but does the slight grinding noise? If so, mine did that and I've actually seen it on a lot of DSM's.

No no grinding noise it more like makes the car jump a little when it pops in gear.

I can better tell the problem if I say the transmission sounds like it has rattling parts inside the smaller section of the tranny. like the opposite end of the bellhousing.

Other than that issue, my car runs smooth..seems to accelerate as it should, gears aren't funky when in gear and car just seems to operate normally other than that...i'm stumped.

Hmmm... I am stumped as well then...

Too bad we never see our DSM guru Kevin around here anymore to solve this one.

I'll record a video of it tomorrow morning with audio.

ok... my assumptions are that you have a heavier clutch (than stock), the transmission isn't completely disconnecting when you push in the clutch...
I'm also assuming the problem with 3rd gear, is that the synchro is wearing out... I'm also gonna assume that there's a possiblity that you have reverse problems (getting into reverse, and a whine when in reverse)

Next time you are in the car, and have trouble getting into 1st, once you have it in 1st, with the clutch pressed, quickly rev the engine, if the car slightly rolls forward, the clutch isn't completely disengaging (clutch release fork bent, clutch fork pivot ball bent, or pressure plate is wearing out)

Also, (on a slightly different note) does your Throwout bearing rattle?
with a heavier clutch, you may want to replace the slave cylinder with an extension rod (or make your own, sry... I don't know the measurements)

I'm gonna think a/b the "rattling" you described... I can almost swear I've experienced something like this... I'm gonna try and see if I can recall what it was...

My buddies 95 GS had sort of a rattle in neutral while it was running and we tore his fucking tranny out twice to try fix it. Once we thought it was a worn TOB and then maybe the clutch fork but it was neither. Then we completely ripped the whole thing apart, put it back together, installed it, and the rattle is still here today. Cannot figure it out.

My TOB and fork went out (had a rattling since install) and busted the bell housing all the way around... (not to say the same thing is/will happen, but that's my experience... I'm trying to think a/b what on the other end of the tranny might rattle)

Mazda, is it full of fluid? Try checking for a loose mounting bracket bolt or something.

Everything is tite as can be. As far as fluids go, I have no friggin clue..all I know is the car was extremely abused before I purchased it and it has only one service record of a mild tune up from the dealership excluding a timing belt and timing belt tensioner. Lol..the car has 175 000 miles on it and it's only a 1999 XD oh well...

Anyways, where would I pop off a inspection bolt to check the fluid level ?

Also here is the video, listen to the raspy sounding rattling after i rev it a little bit. - http://s5.photobucket.com/albums/y18...t=MVI_0807.flv

Ya know what... It almost sounds like the starter gear is grinding in the flywheel... See if it sounds like its coming more from that area...

MazdaX · #26 12-09-2006, 06:55 PM

I pulled the starter off to inspect the gears because if that was the case, running it more = damaging it more lol..starters and flywheel jobs aren't cheap and since I have no garage me no takey tranny out XD

However, the starter gear is in perfect condition with no visible wear signs, I had to replace it when I got the damn car...anywho so I think that eliminates the starter..

The best way to put it is there sounds like a bunch of plastic chip bags inside my tranny being crumbled up..gah..

thats really odd... however, i have heard the same sound on several high milage 420A cas (even Neons) and people have tried tranny rebuilds, new clutchs, flywheels, all with little to no success, however, i'm concered with the way you say "the car jumps when i put it in first" what exactly do you mean by that? Jumps as in starts to roll? if so then your clutch defenatly isn't dis-engaging all the way

Uhh by jumping basically..pop it into gear, goes in very firmly and rough but no gears grind when clutch is fully depressed. From there, once in the shifting motion the car basically jumps about a foot forward and then nuetrals out if I keep the clutch in. It only does that in first gear..hard to explain other than saying it jumps after shifting into first from a dead stop.

Holy shit that sounds horrible, that's definitely not the noise my buddies car made. Check the fluid level in the tranny, it's probably bone dry. Do you have a Haynes or Chiltons manual? It shows how to do it in there, better than I can explain. But you have to pull off the right front wheel and then the splash guard and on the side of the tranny somewhat towards the top there's a rubber plug. If you pull it out and start filling with fluid until it starts to come out the hole, then it's full.

MazdaX · #30 12-11-2006, 09:25 PM

I guess it doesn't matter now..lol The friggin slave cylinder has the shittiest design for a hydrolic clutch system I have ever seen.

stupid flange that bolts up to the mount for the slave broke, the piston jerked sideways and the slave split in half lol..great..Dealership wants 150.00 for a oem replacement and I think thats a bunch of BS for such a simple part..The master was only 80 new...wtf?

So does anyone know where online I can order a slave cylinder for my car ? lol..Engine - 420A. Year - 1999.
