Weird. Things like this never happen to me.
So anyways, I'm out with a few friends. We are teaching a guy how to ride a dirtbike so we go out to this private property by the side of a road. As we pull up, I see this transmission sitting in the weeds. I walk up and find out it's an F2t transmission that had puked all of its guts out. Somebody just dumped it off. Of course I had to take it, I'm getting all the gears out of it. I'm stoked to have found this. Maybe if the spider gears are good I'll take them in for a nice cryotreating session. I guess the question is, is it the drivers or the transmissions that are the problem in our cars? you decide.

WTF? That is crazy...of all the trannys that could have been, it's an f2t? Impressive. I have a feeling though that it was sitting in the weeds for a reason.......

That is crazy. Nice find Brandon.

I definitley say its the tranny's that suck. I mean, who can argue that Mazda trannys don't suck?

If I go past 4500 rpm @ WOT in 1st gear and attempt to change to 2nd( even extremely slowly and carefully) , I ALWAYS grind into second. Even with a brand new tranny. I'm gonna poly the last mount and hope for the best (despite the fact that its the passenger side mount which controls almost none of the rocking/torqing motion.

And while we're on the subject. Someone go sit in their parked car and push in the clutch. Now jerk your foot off, does it come right up with your foot or does it take a second for the pressure to come push the pedal back up?

EDIT:

One more thing Brandon, take a really good look at how the gears and stuff are placed. And take a good hard look at 2nd gear for me, WHY DOES IT DO THAT?

Anyone else have the feeling that the length from 1 to 2 is a LOT longer than say 3 to 4, or even 5 to R (dont do that lol).

It seems as if our shift pattern is at an angle or something.

That's nuts man. Sweet find though. I wish I could find one just laying around. Mine just got rebuilt though by JayB but I am always looking for a spare to build up better. Probably shot peen the gears and all. My main problem (and JayB's) is 3rd gear. He's broken so many of those things it's not even funny. I broke one on mine and I was babying it at the time it broke.
Shannon: I have an ACT extreme pressure plate and 6-puck, so I am not sure if this will help you or not, but my clutch pedal springs right back up. Maybe it's b/c of the stiff PP I have, I dunno.

Yes, the pedal should come right back up.

Shannon, it sounds like you are having problems with your clutch hydraulic system. I think there is probably air in it and/or your slave cylinder needs replacing. Have you replaced it yet? If you've replaced the slave cylinder, it sounds like it needs to be power-bled or the clutch master cyl is bad.

If the clutch hydraulic system is not working properly you WILL have trouble getting into gears as the clutch fork won't be moving as far as it should be. Get underneath the car and take a look at the slave cylinder while someone pumps the pedal and see if the rod is moving fully. This definitely needs to be checked out before you blame the tranny for these problems.

I really don't think these trannies are that bad. I mean, we have Fallguy running 11's on this tranny and his hasn't grenaded yet. I think part of the reason some of these transaxles are blown is that people don't take the time to change the gear oil or fix their shifter bushings and clutch throwout system, then blame the tranny when everything goes to $hit. Perhaps some of you are a bit rough on them for a 15 year old car.

I can, 195k miles on mine, and it does not grind into any gear, Bushings are perfectly tight and it moves silky smooth.


If I go past 4500 rpm @ WOT in 1st gear and attempt to change to 2nd( even extremely slowly and carefully) , I ALWAYS grind into second. Even with a brand new tranny.


Ever driven a big rig truck? There is this thing called Rev-matching. I suggest you learn it.

And you mean Brand New Used tranny right?

What Magik said.

It has to do with people not driving properly, and wearing the 2nd gear synchro ring out. It has nothing to do with the gear itself.


Anyone else have the feeling that the length from 1 to 2 is a LOT longer than say 3 to 4, or even 5 to R (dont do that lol).


Feels the same to me, how are your bushings?

Or maybe its time you cracked the case and put some locking washers on the shift gate. Sounds like your "new" tranny has a few screws missing.

P.S. Nothing in this post is meant to offend, so if you get offended you read it wrong.

EDIT: Damn it stop acting like a 13 year old.

Yeah I still can't believe I found this thing. It's a good example of the old saying "one man's junk, another one's treasure."
I think the person that had it was doing a burnout or somethin and caught traction. I pulled off the 5th gear cover and found a bunch of metal shards everywhere of course, but surprisingly the gears, syncros, and forks all look good in there. Once I get some more time I'm tearing it completely down.

Funny how you bring up the shift angle comment shannon. I agree, it feels like our shift pattern is slightly angled. My friend even said that out of the blue one day when he was sitting in my car shifting. My shift gate will not come loose anymore either, I've got lockwashers, locktite, and overtorqued those bolts.

Mine does the same thing with the pedal not coming up RIGHT away, but it shifts fine anyway...

"or even 5 to R (dont do that lol)".. good luck trying.. once you go into 5th, you CANT go into R until you put the shifter back into its at rest position between 3 and 4... there is a lock on it, so that people cant do that. you can go in your driveway and test it out if you'd like ;)

yeah i think my bushings are COMPLETELY shot. I've gotten used to the feeling of it tho so it doesnt bother me, but when im in any gear i can move it around as if it is in neutral lol.

Mazda trannies suck, plain and simple. Is this not common knowledge? I'm really happy yours is still working.

"Rev-Matching" huh? Lol. It's ok, my REBUILT transmission's syncros are fine so I don't need to "Rev-match" or double clutch.
It's prolly to blame on my clutch hydraulics.

Since I obviously can't "drive properly" maybe you should tell me and the other members on this board with the same problem how you drive? Pretty please?

My bushings are brand new.

Why would I crack the case? The tranny was rebuilt 13k ago. The shift gate is fine, I'd know if it was loose.

If you were really worried about offending me, you wouldn't talk to me like I'm a dumbass.

And, yes, we have had problems with you, and on a personal note, you really frustrate me sometimes. Now if you would like to discuss why I closed that thread you just quoted me from, I'd be glad to discuss this in a PM, or if you want Scooby involved we can do it public in the Feedback forums. Your call.

Ok, I'm done now, feel free to cut this post into pieces and rudely comment on each sentence.

Yes, I'm aware of this 'reverse gate'. Keep in mind its a tiny piece of meteal about the width of a pencil. If it's as strong as the rest of our tranny well, nevermind.

What's the end clearance between the 1-2 shift fork and the 1-2 synchro hub?

Not productive. Define "brand new". Were blocker rings, keys, key tensioner springs, shift forks and synchro hubs replaced?

Returns faster than I can pull my foot up. Sounds like you've got a hydraulic cylinder problem.

Ofttimes people (not you, or course) who incompletely understand the workings of their transaxle develop a habit of resting their right ('cept for Oz and UK) hand on their nifty knob on the end of their nifty STS.

This habit will, of course, cause wear on the shift fork/synchro hub resulting in increased clearance and more slop & vagueness before any meaningfull motion occurs at the hub (same as sloppy bushings in the shifter linkage). Also can result in there being insufficient travel of the hub to properly engage a gear before the nifty STS runs out of travel itself. While the keystone shape of the synchronizers will help complete the engagement (albeit noisily) , continued use will likely grenade the transaxle, leading the user to comment that the machinery sucks (couldn't possibly be the fault of the operator, right?).

Were shift forks and synchronizer hubs replaced during the rebuild?

Just as I thought.

I think if the tranny can handle some 350 p/ft of torque it´s a great tranny, thing is that some wear parameters make it fail for very different reasons. Mainly the worned shifter bushings, and burnouts.
If you make some 190 pound/ft of torque bone stock, and you boost it up to some 240 like I do, and it doesn’t blow due to torque…well, that´s a very good tranny, but if you change your turbo and push it to some 400, 500, or 600 pound/ft of torque - ask Jay B - and it doesn’t blow, or eventually blows the third…well that´s an astonishing tranny.

my tranny is o.k. with 150.000 miles, I´m in the middle of nowhere, and it doesn’t bother me at all. It eventually grinds when shifting hard into second gear but I just found out I have a shot motor mount, all motor mounts are new BUT the one under the VAF. So, there´s my grind.

And yes, all front transmissions need an angle to shift, just that ours seems to be a very narrow angle variation.

Taking what you've learned from something, and using it for your profit later is far more benefitial than just giving up.

P.S. You better lock this thread now, because its not going your way.
