Popping out of third gear?

[Pyr0TeK]

I am guessing this is a tranny issue. Sometimes my car will pop out of third gear, even under regular driving load and not hammering on it. Will grind a little if I shift into third too fast also without giving the clutch time. Thoughts? (help)

It's been a long time since I've been inside a G-series trans. I'll be pulling mine apart in the next few days. If you want to take a look at it yourself I have the factory supplemental transmission service manual.

Thanks... I'm just not sure where to even start ya know? I know nothing about clutches/trannys so I figured I'd ask the best, YOU! Maybe I should start saving for a new tranny and clutch. How hard is it to swap? Is it a total engine pull sort of deal? I am not financially ready to move on this but would you be interested in taking the job if/when I do later on? I would rather a knowledgebale Mazda gearhead like yourself do the work rather than someone I don't know etc etc etc.

It's actually easier to pull the whole motor/trans together. I wouldn't mind taking a look at it. I might be able to source the parts you need out of my broken transmission if needed. I haven't torn it down yet to see what let go.

Cool bro... just keep me in mind when you start tearing it down and put a box together for me and we'll get together sometime in the future. Y0sky and I can head up for a weekend. I'll keep my eyes open for a clutch tranny in the meantime...

I pulled mine apart today. Everything in it is fine except for the diff. We can take the diff out of yours and put into my trans. It would be an easy swap.

I would say check the engine mounts... I had this same problem and once i changed out my rear and pas side mount it hasnt happened again. I even tried the same quick shifting from 2 to 3 to see if it would grind.

Oh yea...forgot about that being an issue as well. You might want to look into replacing the mounts first. If you've never done it I can almost assure you they are torn. I've had solid mounts for so long that I forgot how crappy the stock ones were.

[martispeed]

yea the totally blow!!! But man that rear one is a PITA!!!

[JCell]

take the intake manifold off and its much easier

I Window Weld'ed my passenger side mount but I have not touched the others yet. I know I looked at the front one and it is torn so I'll fill it too. I might as well just Window Weld them all... I just hate the inside rattling to hell and back. Think it would help doing the 3 and leaving the rear or would it be the main culprit?

[martispeed]

truly, i think the rear is the main culprit. I know it sucks... I currently have SLS front, updated side mount and awr rear. The Vibes do suck at times but its good to know that im not grinding third any more, cuz i hated it. I would have to pause to shift into third and sometimes that wouldnt help either. But now all is well, even when its cold outside smooth as butter...

[xelderx]

The rear is the main problem. The motor pivots toward the back under load. The rear one needs to be the most sturdy. I've changed a rear mount with the motor/intake mani in the car before. It's not easy, but it is possible. It would be more efficient to just get a new rear mount and fill it. Then swap it out. Pulling the old out and having to wait for the silicone to cure would take too long for my liking.

Wonder if I can connect a flexible tube to the Window Weld tube and fill it without taking it out? Seems possible but I have not looked at it close enough to see if I can get to it in order to squeeze it in.

...and as stated, you are right about the pivot... I held pressure on it in third gear this morning and hit the gas back and forth and you can feel it bigtime try to move the shifter back...

[xelderx]

It would be very hard to fill it while it's still in the car. Trying to squeeze window weld thrugh a long tube would suck and I'm not sure you could get it in all the holes of the mount with it bolted into the bracket on the transmission.

Yeah you're probably right... that stuff is very tar-like.

This one get torn normally also?

The first link isn't the right design for your car. I think that fits the earlier 3rd Gen 1.8L cars. The second link is the correct style mount. I have no feedback on the quality.

So this is the only answer? just that the engine is pulling on the shift linkage? It has nothing to do with any internals?

I mean it makes sense since this only happens when I am under hard acceleration in a tough corner at the track and I am sure to have plenty of body flex and even though I did DIY the mounts I still see the rear has quite a bit of play, but I cant hold on to the shifter at ever corner. That would be a pain in the back! Not to mention I just replaced the shift forks because I was doing that to keep it in last time it was popping out of third.

Can it be some internal thing like the syncros? I have no problem getting in and out of all gears. and the gears themselves looked great. But not the syncros, they might need to be replaced at some point in the future. but would that have anything to do with this? maybe trans case flex? Bent shift linkage?

any help or input would be great. I am no longer high speed autocrossing, I am now W2W racing and finding stuff like this to be scary at speeds with other cars around me going through corners. BUT I really really dont want to throw parts at this.

[iracemine]

wow thanks for all the feed back. does anyone even own a protege anymore? I try and do searches with google and all it does is bring me back to this swell place.

for others like me in the future; I filled every mount solid, and found that the third gear only still pops out even just driving normally (like track touring) not even acceleration. I can feel the gear catch and toss it out. Soooo I called mazda motorsports development and they said it might be one of two things inside the trans and not the linkages or mounts or any of that. So I am now about to pull the trans out for the second time but with the motor as a whole on a earlier suggestion. Ill post back up with some photos of what did indeed go wrong.

[boostedprotege]

i'm having the same issue as we speak.. but with 2nd gear.. sometimes it'll pop out as soon as i release the clutch but usually as soon as i give it a lil gas.. i was thinkin its the synchros but not to sure.. does anyone have the tranny manuall i can downloan from them?? and anyone know of a good place to source the tranny parts??

[iracemine]

pulling the motor and trans makes it sooooo much easier. of course I don't have any accessorys so that also makes it much quicker. But I found out that I wore out the engagement teeth on third gear and the syncro sleeve teeth, not the syncros. that was fine. I looked at them last time they where out and I could not properly gauge how bad they where, but when the new third gear came in it was abundantly clear they where fucked. so fucked I busted about 75% of the teeth off of the sleeve. put in a new 2/3 hub assembly, third gear, bearing, but held on to the third gear syncro because the new one did not have the carbon friction contact area and the teeth had no wear on them. Also with the mazda motorsports development discount I got some awr front and rear motor mounts for cheaper than you can buy just one of them.

I hope this helps someone, but I will not be able to test this till next season. but even with the motor out I still had to buy a deep well extractor socket from matco to get the nuts off for the rear m/m. damn near pulled the car of the jackstands before they let go!!!!
