gearbox burring

  1. General Nissan Skyline Chat
    This is starting to annoy me now. Basically, there's a burrrring noise coming from the gearbox in 4th and 5th gear when off boost or decelerating. Driving on boost is fine with no noise and gear changes are slick and smooth. Gearbox oil was changed at the last service interval. Im also running...
