Hey guys! I own a JDM Evo 8 and i absolutely love it. Anyway i've had it for a while now with no problems, but the other day when i entered the highway, i couldn't get it into 6th gear. It's like the gear is completely blocked off. All the other gears are working perfectly. I've checked under the bonnet and as far as i can see, everything looks normal. The cables look ok and move freely when being moved by hand. Is this a sychro problem?
