Well, my problem is when im in 3th gear and i want to shift the 4th gear around 5900 rpm or higher i can't engage the next gear because it's make a kind of wall that don't allow me to pass the 4th gear ,but if i hit the cut off in 1-2-3 for example it doesn't make it, but only on 4th gear and i don't know for the 5th gear because once the 4th is block i can't pass any gear until i slow down.

So what can be my problem. master cylinder?

 

LSJ? Slave cylinder (throw out bearing as'sy) getting weak would be my guess. Not disengaging the clutch far enough.

LNF? Aftermarket clutch that needs the ZZP adjustable rod.

 

yeah sorry i forgot to say that i have an LSJ

Thanks

 

I have the same problem this started to happen after I installed the OTTP stage 2 kit.
sub'd for more info.. I am currently on the stock clutch set up..

 

bent clutch rod? u can look by ur clutch pedal to see if it looks straight or bent....if bent replace with this. get the master cylinder as well dont be cheap! when did a pull threw first to 2nd, 2nd wouldnt let engage. so i bought this and it shifts good now. my rod wasnt bent but i dont think the clutch was engaged all the way. something to check into
Cobalt & Ion ---> ZZ Performance

 

i'm sure it's not the rod because i have the stock clutch and samething for blue.

Me i think it's the master cylinder or the throwout bearing of the clutch
