The problem i think some of you guys are talking about is what toyota call JARRA noise. Its a noise in the gearbox caused by backlash of the gears turning which is mostly noticeable during downchanging. i realise that having excessive backlash will cause gear damage and premature failure, but toyota has not acknowledged this as a problem. so relax guys my car does it aswell. so if im not too concerned about it, i dont think you guys should be either. i understand it is so bloody annoying but there is basically nothing to be done about it, its just the way the box is made. thanx for listening, or reading even. ha
