gear switching being rough at times

now somebody tell me im not the only one with this issue, there are random times where my car goes into gear really smooth and sometimes i have to fight with the shifter to get it in gear, like ill be driving and at a stop if i leave the car in neutral then shift to 1st its a smooth transaction, and within that same trip if i stop again and do the samething its almost like i have to break the damn shifter to get it in 1st gear........ same for reverse when im parking at home

i have a 2001 ae 5speed. I also have this problem. all i can think of is that sometimes the gears just don't line up good causing this. i have a B&M short shifter also. I had my transmission rebuilt last year because the bearings were bad and now my 2nd gear synchro is bad i think because if I try to shift fast then it grinds. annoying.

I've had this happen with the reverse gear in numerous manual cars I've driven including a maxima, pretty sure its normal.

Same here man the ES bushings will give you a tighter snug shift and the sts is a really short shift but more precise and gives a nice confident click when it goes into gear but i have the same problem going into second 5 out of 10 shifts will be perfect and the other 5 will be a little notchy.Idk what anyone says maximma clutches and trannies are absolutly Bottom line

I know that situation, but only when the car isn't warmed up, and even then, it has to be really cold out, like below 40.

Coincidentally, I'm swapping my transmission fluid next week. I ran OEM fluid for 7 years, and Redline MT-90 for the last two. Next week I'm going to try Redline's new mix, MT-85.

Maybe try swapping you gear oil. I just swapped my clutch and filled the trans back up with Amsoil GL-4 . I can't believe how much better the shifter feels an goes into gear . Not as notchy feeling.

Fresh gear oil really helped mine but it can still be notchy at times. Shifter bushings wear and cables dry out inside.

I'm 5 speed but mine does this also. If I go from neutral > 2nd > 1st its always smooth though. So its just a habbit now to do that from a stop now.

Change your fluid to Amsoil, makes an unbelievable difference. Also are your shift cables new? Shifting too hard can cause bent shift cables which usually only makes shifting into 1st and reverse difficult. Worn shifter bushing can do the something also.

Shifting to 3rd seems to be the smoothest transition and oh so randomly it will be difficult to get into 3rd, not extremely like 1st and reverse, the difficulty of gettn to 3rd doesn't bother me much as its probebly only happened once or twice

FML!! guy said i didnt have insurance on the car (and i had proof of insurance), he didnt even wanna see it, got a ticket for that and saying my tags are suspended smmfh!!

That sucks man. Amsoil fixed all my issues, aside from the STS mod. I tried the Redline before, but Amsoil is the winner.

Wow. That sucks, man. Silver lining: Should be easy to fight the ticket with proof of insurance. Now, on to the real problem.

This doesn't sound like a gear oil or shifter bushing problem. It's too pronounced. Check your shifter cables and make sure they're not binding. It would be so easy for them to be damaged before or during the swap. One option to eliminate the tranny as the source of the problem is to disconnect the cables and move the selector lever by hand. It should move between the gears fairly easy. Actually, do this first and report back your findings. We'll eliminate the guessing once piece at a time.

Sounds like your shifting or as you titled it (switching) may need a driver mod!
Check your linkage bushings!

IDK WTF? like now it hardly goes into any gears at all, the clutch feels like nothing but air in it, and i cant blame a leak because the resovior is full, and Cmax its not a driver mod, im sure at a complete stop pushing the clutch as if you are trying to break the firewall should have the car go into gear smooth or not... it just doesnt go into any gears, like to just reverse park i had to cut the car off and put it in reverse, start it back up then back up... it doesnt even want to go into neutral anymore

Look under the hood while some one operates the clutch pedal. Make sure it is moving far enough to properly release the clutch. If it's not you may have a slave cylinder or master that is going bad .
If you verify that the clutch is releasing properly you might want to check the fluid level in the transmission. If it's full you may have a bad trans.

Was you car a auto and you swapped it ?

Also check for damage or missing bushings on both ends of the shifter cables.

Let us know what you find out!

did you check the clutch reservoir to make sure its not empty? i had similar issues with the car not wanting to go into gear, and when i checked it, it was bone dry! filled it, bled it, and its been fine ever since..

Well what I found out is that, when I take the shifter trim off there is 2 cables that goes through the shifter assymbly, one of them have a clip and one don't but I highly doubt that's the reason why it won't go into any gears when the car is turned on... its no like this was a problem all the time it just gotextremely bad today so save the driver mod talk as I doubt most of y'all here ca even drive ur own car... this isn't the 1st time I drove a manual car... this is only the 1st one I've owned, when I worked at carmax I drove manual cars on a daly and I can't recall this... not to mention, why of all the weeks I've had it I'm not making a thread about I never ever going into gear...... anyways on to the real problem... if this also help, when I force the car and I mean using 2 hands to get it in reverse there is a loud bang as if the whole engine trans and headers fell out the damn car lol... I don't get it, hopefully I can get ghostmax301 to swing by to at least use his tools to bleed the clutch and see what ele is going on cause I'm confused... I know the slav cyl is used the master cyl is brand new so idk

If your clutch feels like air, that's your problem. If the clutch line isn't bled properly or even if your clutch pedal isn't adjusted properly it will not disengage the clutch enough for it to go into gear. Could also be your slave cylinder, was that new or used?

So.. Wow. Okay, so I could imitate that problem in my 6-speed by trying to shift without pushing the clutch pedal down?

Oh, GH, when the thing is giving you trouble, were you rev-matching to get it into the next gear? Like, when you go to shift from 1 -> 2, did you increase engine speed after it failed to go in, or were you trying to slam it into gear while your engine was back down to idle speed (which should be 650), when it needed to be at, say, 2000 to match?

I don't know how much experience you have with manual transmissions, but it doesn't help your synchros and whatnot when you try to shift into a gear and your engine speed is way off from where it should be. I guess it applies mostly to downshifting, but I don't see why upshifts would be too different.

Lol I see most ppl are trying to go for that driver mod thing... lemme explain, I'm not driving the car..... all I do is turn the car on and and even try to get it in any gear at all... people, this isn't my 1st time driving a manual transmission car so let's skip past the basics as I'm sure I can tell the difference of the car going in gear easily roughly not at all.... I was driving this car for 2 weeks, I'm sure if it all the sudden don't go into 1st through reverse its past the driver mod..

Is the master cylinder OEM nissan parts? When I did my 5 speed swap, I went through 3 aftermarket ones with the same problem till I decided to pay for OEM and its been fine ever since.

Now I've got a hole in my clutch line


EDIT: this reminds me, I gotta place my order for the steel braided unit..

I believe Essential was on to something earlier. Before you start the car push in the clutch, shift to second, then back up to 1st with the clutch still pushed in. I've driven standards my whole life. It seems at some point placing it in 1st gear while parked is common among manual transmissions(I've never owned a brand new car, but have driven fairly new). This quick little series may reduce your problem. I would still disconnect your shifter cables and manually check your shift linkage on top of the tranny if you're sure the clutch is bled adequately.

Give yourself more room by removing the ground bracket if the s/c bolts are really tight. It only takes a couple extra seconds.

Just follow the negative battery cable down to where the slave sits and you will know what we talking about. I believe its a 12mm bolt.

The 2 slave cylinder bolts are 14mm. If that area of the tranny is anything like the 5speed, the bolt closer to the motor will have to be loosened with a regular (possibly the open end side) wrench. The space is too tight for a socket I know. And if I remember correct, a ratchet wrench is too fat also.

o.k so since the last time since ive post, ive been outside bleeding the clutch... changed the slave cyl so its a brand new slave cyl... OEM that comes in a blue box.... the clutch builds up pressure a tad bit faster than with the old slave, however it doesnt build up enough pressure to get the car in gear smoothly... it gets to 2nd and 4th now, and u gotta fight to get it in gear.... there isnt enough pressure built up to get it in gear, and ive been bleeding the clutch for damn near 3 hours so im sure i eliminate that "you havent blead the system enough" i got the clip from datdudes 5.5 to put on my shifter cables so they arent loose, but i dont know what else to think but adjusting the pedal
