Toyota Yaris clutch

Hello friends, I tell you that I have a 2003 yaris, that when I start to start moving the vehicle, I get a little accelerated, or else vibrates as if it wanted to go out and it seems that the wheels would bricar a bit of the ground, in addition to the second or reduce to the second I feel that the lever brings another metal or hits another piece and sometimes second it seems to be stuck and I must have a little more force to climb to third.
Whatever they told me that they could be synchronizers, but I have no idea that they are or have to take the air from the hydraulic mechanism?

I hope I can help you have done a clutch job because if so, it sounds like it was not a well -made job that vibrates you when I want to lift the vehicle sounds like a crooked press of the press
of the problem of the second would have to check the oil level of the box and the viscosity if it does not improve you then if it sounds to me that they are synchronizers but this should see at the time It comes out as with shiny that means that the synchronizers have spent and there if you have no doubt
