5th Gear Pop-out, I searched already...

[nighthawk355x]

I've been searching and I can't find what I'm looking for. My car pops 5th when you accelerate, it'll go in fine, no grinding at all, it stays in when you're coasting but when you accelerate it pops out.

I've seen a few posts on it when I searched but none had what I was looking for. I realize it may need a rebuild, but I'm not going to just jump in and do it without exploring the simpler options. That said, I heard there's a problem with something coming loose on 5th and all you have to do is pop the trans cover off, tighten it, and you're good. And to me it sounds like something is loose.

Well, that's fine, but does anyone have a link to the steps in doing it or pics of what I need to be looking at? I found a few links but none work anymore.

If u look at the transmission from your passenger side wheel well you have to take them bolts off the transmission case and the big nut is the top nut. It is not the middle one. But if your car is popping out of 5th gear it is more then likely your syncros are going bad like mine were. Replaced and its fixed.

My bad didnt realize u had a 2g n/a my advise does not do any good for you sorry i know nothing of the 2g n/a trans

This is only on turbo cars, unless you have a spyder N/T, then it will work for you, but if you have the 420 engine which it has the motor on the passenger side and transmission on the driver side, this is a totally different transmission.

The Geocities page went DOWN, but fortunately I found it with the way back machine search tool:

This should be added to the Tech section...

When doing this procedure, would putting in Synchromesh fluid be advised when re-filling the tranny with fluid?

Please do not use syncrmesch. Too thin..go with a full synthetic. Gl 4 best imo is redline mt 85

FWIW, here's a picture of said nut (the off-centered synchro is resting on it):

Mine was 3 full turns lose

There wasn't any noticeable damage to the end cap or reverse cone but I'm going to put a new wave spring in there for good measure.

Since I've gone this far, I MIGHT as well throw in a taller 5th: EVOIII 5th Gear Set - Jacks Transmissions LLC

My hands are dirty again so I gotta make this a happy experience!

Hopefully someone can help me. I have a 2g with the 420 engine,the 5th gear was popping out when i first got it. It eventually got to the point to where i couldnt even get it into gear and it would just grind so i stopped trying so i wouldnt mess up my 5th gear to bad. The past couple weeks i have put new syncros and bearings and 5th gear shift fork (mine was badly worn) in my transmission and while doing so, i checked my gears and they all looked good. I have also put new motor mounts in and i have checked the linkage. I am now able to go into 5th gear again but when i accelerate it pops out. This is starting to get frustrating because i have done everything that i have been told to do by other people and although it has helped, it has not fixed it completely. if anyone could give me advice on anything else i could do or look over again that would be great.

I just got my trans back from shep and mine is doing this. The shifter does not move around but it pops out of 5th all the time. i have like 300 mils on the trans. The 36mm nuts are tight. Anything i can look for? besides messing with the shifter cables more.?/
