Hi! I have a g60 Corrado with 020. Because the tunnels are little bit different (Golf mk2 vs Corrado), gear linkage is little bit higher on the shifter stick side than engine side. Did the linkage alignment with homemade tool. Engine off, straight gears go in really smoothly. Reverse not so much. When engine is on, straight gears are okai, not so smooth than engine off and reverse go in only with clunk which is pretty loud. Even the car will jump a little bit. Switching to first, then second and after that to reverse don't change much. Also tried to tension clutch cable as much as I can didn't help. What could be the issue? It can't be clutch cable and I don't believe it is linkage. Something inside gearbox? Oil level too low?
