1995 Chevy Cavalier Won't Shift Running
Did you bleed the system?
Run the lines and fitting with you hand to insure you don't have a leak causing it to suck air
IT is possible that you have a bad compoment. Loosen the liine from the master cyl and have someone press or pump the pedal to see if you have fluid comming from the master cyl. If not then it is the master cyl. If you do then it is the slave cyl.
Good luck
Suggested Repair
Bleed the clutch hydraulic system and check lines and fittings by hand for leaks that can draw in air. Loosen the line at the master cylinder and have someone pump the pedal: no fluid points to a bad master cylinder; fluid present points to the slave cylinder even if it was recently replaced.
Conversation Summary
A 1995 Chevrolet Cavalier with a manual transmission shifts through all gears with the engine off but will not shift once running, despite replacement of the shift assembly, clutch master cylinder, disc, pressure plate, cables, and hydraulic release bearing, plus a full bleed. The expert suggested checking the slave cylinder and pumping the pedal. After the owner said a new slave was installed, the expert advised confirming the bleed, inspecting lines for leaks or air, and testing fluid output from the master cylinder to isolate a bad master or slave cylinder.
