A "slippery noise"??
What make and model of car?
Does it do it when not at high loadings?
How many kms on the car?
Reading between your vague lines:
If it does it when shifting and not when the clutch is released (I assume, as you have some text missing), then it sounds like you are overtaxing the synchro by shifting too fast. That will give you a noise that sounds like a "slippery noise" which is friction between the synchro driving and driven rings.
Try shifting slower and let the synchro do its job properly.
