Toyota Repair: Troubleshooting Toyota pickup clutch issues, minute teeth, clutch cylinder

Question
I have a '87 2WD five speed Toyota pickup (170k) that is becoming harder and harder to get into gear. At this point it's a ten minute, teeth gritting, ordeal to get it going out of the driveway - it just about refuses to go into first. But once it's moving I can usually get it from third and up smoothly but with some force.  The clutch pedal has become increasingly soft to the point were it will now go almost all the way to the floor with very little resistance. The fluid level in the clutch cylinder is good and dose not seam to have dropped even though the soft pedal makes it feel like a hydraulic pressure issue. When I start the truck in gear, even with the clutch pedal pressed to the floor, the transmission is almost fully engaged – causing the engine to stall most of the time. The transmission otherwise feels good…for now.

Answer
There may be a problem with either one or both of the hydraulic cylinders even if they're not leaking, there may be an internal problem which causes the fluid to bypass, check the movement of the slave cylinder on the bellhousing, when depressing the pedal all the way the pushrod on the slave cylinder should push the clutch release arm about an inch and a half, if this doesn't happen replace both the master and slave cylinders.
