Did a search, read dozens of threads, could not find the answer. It's actually a rather simple question: In fifth, when I step on the gas the stick actually moves back a bit in my hand...but it never pops out of gear. I'm just wondering how worried I should be.

not very, that just tells you that your motor mounts are weak... anything done to the mounts?? i have 3 mounts that are done and the shifter still moves.

I don't know if the last owner ( I just got the car on Saturday) ever did anything with the motor mounts....I guess I can check those out. Is there a good place to get replacement ones, or aftermarket ones that reduce engine vibration?

i thought that leaving bad motor mounts can actually cause the 5th gear popout after a while.

you may want to check the tightness of the rear motor mount bolts(acctually bolt to the tranny) mine were loose and the shifter moved! hope this helps!
if this doesnt help, then try getting the ES motor mount inserts from:
http://www.suspension.com/nissancars.htm you'll only want the "torque mount" inserts. let me know if you need advice to put these in.

I agree, check those bolts. You have to get under the car and then torque them around 35lbs, but those bleedin things fall out anyway so hit them with a bit of liquid Lock-Tite. I would say motor mounts also. The trany is not too hard to work on so if you have the time and your sure it's the original trany, then drop it and replace the 5th gear snap ring (or buy a used one. $500). Too many people wait until the gear starts poping out and then you have loose metal bits. The truth is, the 5th gear pop out is NOT caused souly by a gear design flaw, it's because the snap ring was thinner on the earlier tranys and that's one of the changes to the updated input shaft. more space for a thicker snap ring.

I just got thru the same ordeal Morpheus. Here is the key question I have for you:

Does the shfiter do this in ANY other gear besides 5th?

If yes, time to open tranny. I know what it is!

If no, which is saying that the shifter moves quite a bit in the other gears in the same fashion... then its the mounts.

One other question Morpheus:

Did it start this behavior in 5th literally overnight? Mine did. I went from no problem one morning (0-60k miles no problem) to riding in my car that same afternoon with a friend, getting up to speed on the highway, set cruise, (hand still on the shifter) and *boom* shifter movement? WTF is that?!?!? (I said to James next to me)

Even if your mounts are ok your shifters gona move a little bit since we dont have any of those crap cable shifters and the stock motor mounts of course have play in them.

As in previous posts motor mounts do nothing to prevent 5th gear popout. I own JWT solid motor mounts and they do noting for that. I work on se-r's and nx2000's daily. In oder to fix the 5th gear pop out all you need to do is take the tranny out and flip 5th gear over. In the tranny only half of the teeth on that gear make contact. What happens is the teeth on the gear go bad causing 5th gear pop out. So take out the tranny and flip the gear now you have a practically new gear, and no need for a new tanny or a new 5th gear.OUT OF POCKET EXPENSE IS 0, ALL IT COST YOU WAS YOUR HARD WORK AND ELBOW GREASE. If anyone needs tech support feel free to email me. Also for all you new racers out there that are new to the SR20DE scene remember not to do BURN OUTS till you weld your tranny. Because wheel hop from the burnout causes the tranny to crack where the drivers side CV shaft goes into the tranny.

I'm sorry Mel but I have to respond to this in saying that it is just plain incorrect information and bad advice. You may have the best intentions and I'm certainly not trying to be negative or flame you but from someone who just got through completely disassembling his own tranny and repairing it successfully I know it to be wrong first hand.

'Fifth gear' itself can NOT be flipped over. You may be referring to the synchro hub which ALSO has a correct orientation EVEN though it appears that it can be easily flipped. Anyone and I repeat this ANYONE who thinks that they can go inside a tranny and repair 5th gear without measuring, checking, and inspecting parts as the FSM prescribes is taking an enormous risk of having it fail immediately or in short order thereafter. (I'm not the first to say this) It's a lot of work to go in there, why not fix it correctly?

There are several on this forum and the mailing list who have had their 5th gear problem repaired in a cheap unthorough manner and it has come back to haunt them 'weeks' later. I would hate to see it happen to someone in the future because if it does, it will cost them more in the end in terms of money and down time.

Good luck.

I have done this on my 1991 nx2000 and on many other sr20de's. I did this about 10 months ago and have had no problems since then. Not sure what you mean that 5th gear can not be flipped over. Done it in my tranny. SO as a stated before and will state again. This is what needs to be done to have no out of pocket expense. I GUESS YOU ARE GOING TO TELL ME NEXT THAT YOU DONT NEED TO REINFORCE THE TRANNY DO TO WHEEL HOP. Im just hear to give advice and help others out. Thankyou. I work on SR20DE'S AND SR20DET'S DAILY. FROM INSTALLING GTI-R MOTORS ORDERED FROM JAPAN IN SER'S AND NX2000'S AND WHAT EVER ELSE YOU CAN NAME.

Bullshit.

What we have here is 5th gear. As you can see nothing to FLIP here: http://www.talley-stroud.com/thomas/MVC-671F.JPG


Now here in this pic we have the synchro hub. This only uses one side and despite that it is made to go in the the tranny a certain way. Jay Stewart for example put a brand new one of these in his tranny and when he went to shift it after he had the tranny back in the car, it wouldn't go into 5th. He took apart and realized EVEN THOUGH it only uses one side it has a machined ORIENTATION. He had it in backwards.

If this above is what you are talking about, my friend that is NOT the reason why 5th pops out.

Sit down for a few minutes and read this page: http://www.se-r-list.org/fifth.gear.phtml
Larry practically documented this stuff YEARS ago. Look particularly at the newly designed 5th gear.

No I never said anything about that part. Do NOT put words in my mouth. My own tranny case here:
