Nissan Sentra cold transmission failure

Good evening, I have a Nissan Sentra Model 92, my problem is that in the morning the changes do not enter normally and what I do is put the change off so that I can move forward, after a while pulling they re -enter normally, about 4 months ago they changed the new clutch, pasta, collar and press, I just lack rectifying the steering wheel, but before they do not make this problem in perfect condition problem, I thought the clutch had been mismant but not the adjustment is fine, check oil level and okay .., and there they told me that I check my clutch may not be I turned off the engine is that everything was fine ... which I did and if the car went out ...

I do not know if that engine is straight or cash on the side but look at the lever to the box if we carry some gear selection cables and the tires that take the shift levers are bad and that's why they have a game and scratch march. If that were not the synchronizers inside the box are bad and over time it will be time to open and change them or scratch box.

I go to put some photos but I don't know what exhausts that I don't put them on and they don't see me, if someone reads this and makes the fabor to explicate how I can put photos in the forum, which I look for the file and it does not come out.

Friend changes the oil from the box (75W90) End of the problem.

Thank you very much to those who answered my question:
the solution was:
(change the clutch kit)
because Clutch's paste, one of the springs was broken, which after heating no longer wanted to enter the changes in a normal way ...
