93 Z28 with an M6 and today it started to become very difficult to shift into any gear, especially 1st and reverse. I had to jam it pretty hard to get it into gear and drive it home. When I got there I checked the slave cylinder reservoir and it was completely empty. I'm assuming this would indicate a leak somewhere??? I filled it back up with fluid - don't see any drips - but shifts are still very difficult. Any ideas? Thanks.

 

Have you checked the tranny fluid level? Also did you bleed the clutch system? You may still have air in the lines. I am using a 93 tranny and I had similar problems...

Good luck.

If both of those arn't the case you may want to replace the Master/Slave assm. Pretty easy R/R

 

After letting the car sit for several days it is shifting OK now. Strange...only thing I did was fill up the fluid reservoir with DOT3 and let it sit.
