Hey guys. My manual disco has decided to play up changing gears. Now with the car off I can select any gear. With the car off I can put it in any gear, start the car and release the clutch and the clutch works and the car moves. With the car on if I try and select a gear it won’t even let it try and engage it’s like it’s blocked from going into gear. You can push as hard on the gear stick as you like nd it just won’t go in on any gear. I did luckily manage to get into first and reverse yesterday just to move the car out of the way but it wasn’t easy. Any suggestions on what to start looking at? I’m assuming the clutch is fine as it still engages and bites when I can get it in gear so don’t know enough about discos to fault find on my own.

Cheers
