i just bought 99 se with MT. my gears are shifting notchy.. specially when i am trying to sport shift.. or racing..? any solution please let me know..?/ thank u

 

I felt the same way when I got my I30t 5 speed...I was able to drive any other stick shift perfectly but this one I couldn't shift smoothly...It took me about 3 months to be able to drive it normally, so all I can say is give it time.

 

Mine has shifted notchy since day one. Even after I had a new tranny put in it still shifts a bit notchy. I think my linkage might be a little messed up cause every now and then I have trouble getting it into first at a dead stop. It will only go half way into gear until I push the clutch in twice then it goes in. It's fine in every other gear but both the trannys I had did this. It seems a lot of people complain about having a notchy tranny but I guess that's just the way maximas and I30s are. But i've never had a problem shifting while racing. You just have to get used to it.

 

My '99 gives me trouble once in awhile. I owned a '97 maxima before this one and it never seemed to fight back like this one. I heard that redline MT-90 is a nice synthetic gear lube. I'm looking into getting some to help with this problem.

 

Several potential reasons:
1) worn shifter bushings
2) you can't shift, you're not holding the clutch in long enough, or (bad case) the clutch isn't disengaging properly). The vast majority of those who think they're 'race shifting' are really, really bad at it, and synchromesh transmissions don't last long under that kind of abuse.
3) the synchros and/or gear dogs are damaged
4) the wrong oil is in the gearbox. GL-5s are everywhere, but their extra-low friction can prevent the synchros from properly stopping the gears. Switching to a true GL-4 like Redline MT-90 can solve this problem.

The tranny in ours cars is obviously nothing like a Mazda or Honda tranny where theirs are just silky smooth and precise.

I have encountered the problem NYC sees every once in a while. Where I try to put it in 1st at a light and it won't go unless I release the clutch and push it in again.

One thing that definetly helps the notchiness though is some different gear lube. I put Amsoil GL-4 in the tranny about 2 months ago. I love the way it feels. It glides right in a lot less notchy. I suggest a fluid change!

 

so u guyz recommands changing a gear oil.. which one should i go with with red line or amsoil...let me know thank u

 

Both are good - choose your poison. Make sure it's the GL-4 version, both brands sell multiple varieties.

I also have amsoil. I noticed a slight improvement when I put it in. Theres someone in the group deal forums offering %25 off on all amsoil products. I got mine from him.

 

myoilshop.com sells redline, I have bought from them twice. Amsoil and redline are both good.
