I have a 1995 chevy C1500 2WD 5 Speed manual transmission truck and recently its been getting hard to shift. The only time that it's difficult to shift it when im at a dead stop and I try to shift into 1st gear. I have to really force it sometimes to get it to go into gear. It also seems like it's a little bit harder to shift in general. I noticed that if im idling and I pus the clutch in and try to shift into 1st or any other gear its very difficult. But as soon as I shut it off it shifts into all gears easily until I start it again. The clutch is only about 2 years old so I don't think its a bad clutch. It almost seems like the clutch pedal doesn't really do to much until as it used to. Also how would I be able to find out if its a bad master or slave cylinder that's causing the problem. Nothing is leaking and the fluid level is perfect. These are the original cylinders and the truck currently has 225k miles on it. The only reason I think its a hydraulic problem is because yesterday it was perfectly fine and today all of a sudden its giving me problems. It wasn't much of a gradually getting worse thing. Thank you for your time and help all!
