Hi all, when in low rpm (usually after changing gears) i get really bad gearbox vibration, i have to rev past 3k (in first gear) so when i engage the next gear it doesnt vibrate, which you can understand makes baby jesus cry in the morning when the car is cold. it does this with all gears if the rpm is low enough, but as the gears raise the vibration is easier to avoid since raising the rpm to change gears isnt as painfull.
the vibration goes away shortly as i raise the rpm but it is quite bad and even loud through the car.
ive had the same issues with previous skylines, but the vibration was easier to avoid and you didnt have to rev as high to avoid vibration in the next gear.
any ideas what it could be?
