I have a volvo S40 1.6 (S reg) 1998 Manual gears. The problem i have is that the Gearshift jams and is difficult to release. This happens when using 1st to 4th gears. It's getting really hard to release the gearshift at times and gets really frustrating when in traffic. I blead the clutch just to see if there was a problem there and found air that i got rid of. This seemed to cure the problem for a little while but the problem returned. I am wondering if it could possibly be the slave cylinder seals that have gone but not sure. Hope there is someone who has had similar problems with changing gears and can help me.
