Hydrauli Clutch Question/Problem

[larryboz]

Got 88 K5 with 4 speed in it. Well it has been sitting a while so I went to move it and push clutch in started it and the truck moved like the clutch wasn't dis-engaging. Anyway got it started and if I move my foot a little it takes off but can't get it into any gear with it running. Turn it off and it will go into any gear. Checked Master cylinder and it was empty, filled and bled it but still the same. Any thoughts would greatly be appreciated.

You've got to figure out what part was leaking, the master, the line or the slave cylinder, and replace it, then re bleed the system. and when you bleed it, you have to keep the slave cylinder from moving, I cut a block of wood that I wedge between the fork and the trany crossmember. if you try to bleed it without blocking it, you will never get all the air out.
