I've been helping a friend of mine out on his 5th gen 2001 honda prelude sh and he's been having trouble with rough shifts and eventually it would not go into gear whatsoever. He then proceeded to replace the master and slave cylinders. The problem still persists. The lines will not keep pressure as if there is a leak of somekind however upon inspection of every joint and kink possible there is no sign of leakage. After bleeding about a thousand times after going down the road about a mile the clutch just gives out and sinks to the floor. Replacing all of the lines will cost upwards of $188.60 and we are trying to avoid spending money on something that will not fix the problem. Any suggestions?
