Everything seems to be fine except when I get to around 2000 rpm and I am in the throttle pretty good the rooms will jump up about 500 and it feels like the transmission is slipping. I have check the clutch fluid reservoir and it is full just checked the transmission fluid it is nice and red still and full. It just started doing it 2days ago. Any suggestions what might be causing it? A friend said the slave cylinder might be going out but not sure. I can grab the slave cylinder and it wiggles pretty good. Is that normal are should it be tight? Thanks Gavin

There is no adjustment to this, the clutch may be going bad or you can take the slave off and pump the rod by hand a few times to get air out. Then reinstall if no clutch pedal then press it to the floor a few times to get it back.

Should you be able to wiggle the slave cylinder when installed are should it be tight with little movement by grabbing it and wiggling it with your hand?

Because of age and mileage it is going to move some new it would not, but I do not think that would do much. Try what I had suggested in first reply if that does not work then it is most likely a clutch problem.
