I drive a hyundai tiburon gt and my stopped shifting into gear while I was at a stop light. Now it doesn't go into gear at all even when the car is off. The clutch pedal still has pressure when I press it but the shifter won't engage into gear. Can someone please help me?
Either the shifting mechanism has slipped so it needs adjustment or the gearbox has a problem - if the second it will need to come out for repair.
Has the oil level been checked?
Another possibility is that the clutch slave cylinder might have failed.
I don't know Hyundai, but I confirmed it is a master/slave setup. In general the clutch pedal works a master cylinder on the firewall near the brake master cylinder, which uses fluid to activate the slave cylinder which pushes a lever to disengage the clutch plates. If you can trace the fluid line to find the slave, you can have a helper activate the pedal and see if the slave is moving the lever or not.
If it's failed, luckily it's a $20 part...
