Hello, I'm having problems with my clutch. The pedal dropped to the floor. The resorvoir was low. Replaced clutch master cylinder and slave cylinder, adjusted pedal, replaced clutch switch, now my cltch will not go into gears when running. it is not engaging or disengaging

 

So we are on the same page,

When you replaced the master and slave cyls, did you bleed all the air out of both?
If you did not,,,,,,,,,,,,,,, we can compress air and if there is any air trapped in that system the force that should be sent to the slave cyl is possibly compressing that trapped air and not transferring the full hydraulic pressure down to the slave cyl.. If that is what is happening , the clutch can't fully release and therefore shifting into gear with the engine running is difficult if not impossible..Before getting into a long winded post, suppose we stop here and see what some of your answers might be, OK ?
